# NTLM Implementation for Go
This is a native implementation of NTLM for Go that was implemented using the Microsoft MS-NLMP documentation available at http://msdn.microsoft.com/en-us/library/cc236621.aspx.
The library is currently in use and has been tested with connectionless NTLMv1 and v2 with and without extended session security.
## Usage Notes
Currently the implementation only supports connectionless (datagram) oriented NTLM. We did not need connection oriented NTLM for our usage
and so it is not implemented. However it should be extremely straightforward to implement connection oriented NTLM as all
the operations required are present in the library. The major missing piece is the negotiation of capabilities between
the client and the server, for our use we hardcoded a supported set of negotiation flags.
## Sample Usage as NTLM Client
```go
import "github.com/ThomsonReutersEikon/go-ntlm/ntlm"
session, err = ntlm.CreateClientSession(ntlm.Version2, ntlm.ConnectionlessMode)
session.SetUserInfo("someuser","somepassword","somedomain")
negotiate := session.GenerateNegotiateMessage()
<send negotiate to server>
challenge, err := ntlm.ParseChallengeMessage(challengeBytes)
session.ProcessChallengeMessage(challenge)
authenticate := session.GenerateAuthenticateMessage()
<send authenticate message to server>
```
## Sample Usage as NTLM Server
```go
session, err := ntlm.CreateServerSession(ntlm.Version1, ntlm.ConnectionlessMode)
session.SetUserInfo("someuser","somepassword","somedomain")
challenge := session.GenerateChallengeMessage()
<send challenge to client>
<receive authentication bytes>
auth, err := ntlm.ParseAuthenticateMessage(authenticateBytes)
session.ProcessAuthenticateMessage(auth)
```
## Generating a message MAC
Once a session is created you can generate the Mac for a message using:
```go
message := "this is some message to sign"
sequenceNumber := 100
signature, err := session.Mac([]byte(message), sequenceNumber)
```

=======
[![Build Status](https://travis-ci.org/davecgh/go-spew.png?branch=master)]
(https://travis-ci.org/davecgh/go-spew) [![Coverage Status]
(https://coveralls.io/repos/davecgh/go-spew/badge.png?branch=master)]
(https://coveralls.io/r/davecgh/go-spew?branch=master)
Go-spew implements a deep pretty printer for Go data structures to aid in
debugging. A comprehensive suite of tests with 100% test coverage is provided
to ensure proper functionality. See `test_coverage.txt` for the gocov coverage
report. Go-spew is licensed under the liberal ISC license, so it may be used in
open source or commercial projects.
If you're interested in reading about how this package came to life and some
of the challenges involved in providing a deep pretty printer, there is a blog
post about it
[here](https://blog.cyphertite.com/go-spew-a-journey-into-dumping-go-data-structures/).
## Documentation
[![GoDoc](https://godoc.org/github.com/davecgh/go-spew/spew?status.png)]
(http://godoc.org/github.com/davecgh/go-spew/spew)
Full `go doc` style documentation for the project can be viewed online without
installing this package by using the excellent GoDoc site here:
http://godoc.org/github.com/davecgh/go-spew/spew
You can also view the documentation locally once the package is installed with
the `godoc` tool by running `godoc -http=":6060"` and pointing your browser to
http://localhost:6060/pkg/github.com/davecgh/go-spew/spew
## Installation
```bash
$ go get -u github.com/davecgh/go-spew/spew
```
## Quick Start
Add this import line to the file you're working in:
```Go
import "github.com/davecgh/go-spew/spew"
```
To dump a variable with full newlines, indentation, type, and pointer
information use Dump, Fdump, or Sdump:
```Go
spew.Dump(myVar1, myVar2, ...)
spew.Fdump(someWriter, myVar1, myVar2, ...)
str := spew.Sdump(myVar1, myVar2, ...)
```
Alternatively, if you would prefer to use format strings with a compacted inline
printing style, use the convenience wrappers Printf, Fprintf, etc with %v (most
compact), %+v (adds pointer addresses), %#v (adds types), or %#+v (adds types
and pointer addresses):
```Go
spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
```
## Debugging a Web Application Example
Here is an example of how you can use `spew.Sdump()` to help debug a web application. Please be sure to wrap your output using the `html.EscapeString()` function for safety reasons. You should also only use this debugging technique in a development environment, never in production.
```Go
package main
import (
"fmt"
"html"
"net/http"
"github.com/davecgh/go-spew/spew"
)
func handler(w http.ResponseWriter, r *http.Request) {
w.Header().Set("Content-Type", "text/html")
fmt.Fprintf(w, "Hi there, %s!", r.URL.Path[1:])
fmt.Fprintf(w, "<!--\n" + html.EscapeString(spew.Sdump(w)) + "\n-->")
}
func main() {
http.HandleFunc("/", handler)
http.ListenAndServe(":8080", nil)
}
```
## Sample Dump Output
```
(main.Foo) {
unexportedField: (*main.Bar)(0xf84002e210)({
flag: (main.Flag) flagTwo,
data: (uintptr) <nil>
}),
ExportedField: (map[interface {}]interface {}) {
(string) "one": (bool) true
}
}
([]uint8) {
00000000 11 12 13 14 15 16 17 18 19 1a 1b 1c 1d 1e 1f 20 |............... |
00000010 21 22 23 24 25 26 27 28 29 2a 2b 2c 2d 2e 2f 30 |!"#$%&'()*+,-./0|
00000020 31 32 |12|
}
```
## Sample Formatter Output
Double pointer to a uint8:
```
%v: <**>5
%+v: <**>(0xf8400420d0->0xf8400420c8)5
%#v: (**uint8)5
%#+v: (**uint8)(0xf8400420d0->0xf8400420c8)5
```
Pointer to circular struct with a uint8 field and a pointer to itself:
```
%v: <*>{1 <*><shown>}
%+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)<shown>}
%#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)<shown>}
%#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)<shown>}
```
## Configuration Options
Configuration of spew is handled by fields in the ConfigState type. For
convenience, all of the top-level functions use a global state available via the
spew.Config global.
It is also possible to create a ConfigState instance that provides methods
equivalent to the top-level functions. This allows concurrent configuration
options. See the ConfigState documentation for more details.
```
* Indent
String to use for each indentation level for Dump functions.
It is a single space by default. A popular alternative is "\t".
* MaxDepth
Maximum number of levels to descend into nested data structures.
There is no limit by default.
* DisableMethods
Disables invocation of error and Stringer interface methods.
Method invocation is enabled by default.
* DisablePointerMethods
Disables invocation of error and Stringer interface methods on types
which only accept pointer receivers from non-pointer variables. This option
relies on access to the unsafe package, so it will not have any effect when
running in environments without access to the unsafe package such as Google
App Engine or with the "disableunsafe" build tag specified.
Pointer method invocation is enabled by default.
* ContinueOnMethod
Enables recursion into types after invoking error and Stringer interface
methods. Recursion after method invocation is disabled by default.
* SortKeys
Specifies map keys should be sorted before being printed. Use
this to have a more deterministic, diffable output. Note that
only native types (bool, int, uint, floats, uintptr and string)
and types which implement error or Stringer interfaces are supported,
with other types sorted according to the reflect.Value.String() output
which guarantees display stability. Natural map order is used by
default.
* SpewKeys
SpewKeys specifies that, as a last resort attempt, map keys should be
spewed to strings and sorted by those strings. This is only considered
if SortKeys is true.
```
## Unsafe Package Dependency
This package relies on the unsafe package to perform some of the more advanced
features, however it also supports a "limited" mode which allows it to work in
environments where the unsafe package is not available. By default, it will
operate in this mode on Google App Engine. The "disableunsafe" build tag may
also be specified to force the package to build without using the unsafe
package.

printing functions. The formatter is useful for inline printing of smaller data
types similar to the standard %v format specifier.
The custom formatter only responds to the %v (most compact), %+v (adds pointer
addresses), %#v (adds types), and %#+v (adds types and pointer addresses) verb
combinations. Any other verbs such as %x and %q will be sent to the the
standard fmt package for formatting. In addition, the custom formatter ignores
the width and precision arguments (however they will still work on the format
specifiers not handled by the custom formatter).
Typically this function shouldn't be called directly. It is much easier to make

Package spew implements a deep pretty printer for Go data structures to aid in
debugging.
A quick overview of the additional features spew provides over the built-in
printing facilities for Go data types are as follows:
* Pointers are dereferenced and followed
* Circular data structures are detected and handled properly
* Custom Stringer/error interfaces are optionally invoked, including
on unexported types
* Custom types which only implement the Stringer/error interfaces via
a pointer receiver are optionally invoked when passing non-pointer
variables
* Byte arrays and slices are dumped like the hexdump -C command which
includes offsets, byte values in hex, and ASCII output (only when using
Dump style)
There are two different approaches spew allows for dumping Go data structures:
* Dump style which prints with newlines, customizable indentation,
and additional debug information such as types and all pointer addresses
used to indirect to the final value
* A custom Formatter interface that integrates cleanly with the standard fmt
package and replaces %v, %+v, %#v, and %#+v to provide inline printing
similar to the default %v while providing the additional functionality
outlined above and passing unsupported format verbs such as %x and %q
along to fmt
Quick Start
This section demonstrates how to quickly get started with spew. See the
sections below for further details on formatting and configuration options.
To dump a variable with full newlines, indentation, type, and pointer
information use Dump, Fdump, or Sdump:
spew.Dump(myVar1, myVar2, ...)
spew.Fdump(someWriter, myVar1, myVar2, ...)
str := spew.Sdump(myVar1, myVar2, ...)
Alternatively, if you would prefer to use format strings with a compacted inline
printing style, use the convenience wrappers Printf, Fprintf, etc with
%v (most compact), %+v (adds pointer addresses), %#v (adds types), or
%#+v (adds types and pointer addresses):
spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
Configuration Options
Configuration of spew is handled by fields in the ConfigState type. For
convenience, all of the top-level functions use a global state available
via the spew.Config global.
It is also possible to create a ConfigState instance that provides methods
equivalent to the top-level functions. This allows concurrent configuration
options. See the ConfigState documentation for more details.
The following configuration options are available:
* Indent
String to use for each indentation level for Dump functions.
It is a single space by default. A popular alternative is "\t".
* MaxDepth
Maximum number of levels to descend into nested data structures.
There is no limit by default.
* DisableMethods
Disables invocation of error and Stringer interface methods.
Method invocation is enabled by default.
* DisablePointerMethods
Disables invocation of error and Stringer interface methods on types
which only accept pointer receivers from non-pointer variables.
Pointer method invocation is enabled by default.
* ContinueOnMethod
Enables recursion into types after invoking error and Stringer interface
methods. Recursion after method invocation is disabled by default.
* SortKeys
Specifies map keys should be sorted before being printed. Use
this to have a more deterministic, diffable output. Note that
only native types (bool, int, uint, floats, uintptr and string)
and types which implement error or Stringer interfaces are
supported with other types sorted according to the
reflect.Value.String() output which guarantees display
stability. Natural map order is used by default.
* SpewKeys
Specifies that, as a last resort attempt, map keys should be
spewed to strings and sorted by those strings. This is only
considered if SortKeys is true.
Dump Usage
Simply call spew.Dump with a list of variables you want to dump:
spew.Dump(myVar1, myVar2, ...)
You may also call spew.Fdump if you would prefer to output to an arbitrary
io.Writer. For example, to dump to standard error:
spew.Fdump(os.Stderr, myVar1, myVar2, ...)
A third option is to call spew.Sdump to get the formatted output as a string:
str := spew.Sdump(myVar1, myVar2, ...)
Sample Dump Output
See the Dump example for details on the setup of the types and variables being
shown here.
(main.Foo) {
unexportedField: (*main.Bar)(0xf84002e210)({
flag: (main.Flag) flagTwo,
data: (uintptr) <nil>
}),
ExportedField: (map[interface {}]interface {}) (len=1) {
(string) (len=3) "one": (bool) true
}
}
Byte (and uint8) arrays and slices are displayed uniquely like the hexdump -C
command as shown.
([]uint8) (len=32 cap=32) {
00000000 11 12 13 14 15 16 17 18 19 1a 1b 1c 1d 1e 1f 20 |............... |
00000010 21 22 23 24 25 26 27 28 29 2a 2b 2c 2d 2e 2f 30 |!"#$%&'()*+,-./0|
00000020 31 32 |12|
}
Custom Formatter
Spew provides a custom formatter that implements the fmt.Formatter interface
so that it integrates cleanly with standard fmt package printing functions. The
formatter is useful for inline printing of smaller data types similar to the
standard %v format specifier.
The custom formatter only responds to the %v (most compact), %+v (adds pointer
addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb
combinations. Any other verbs such as %x and %q will be sent to the the
standard fmt package for formatting. In addition, the custom formatter ignores
the width and precision arguments (however they will still work on the format
specifiers not handled by the custom formatter).
Custom Formatter Usage
The simplest way to make use of the spew custom formatter is to call one of the
convenience functions such as spew.Printf, spew.Println, or spew.Printf. The
functions have syntax you are most likely already familiar with:
spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
spew.Println(myVar, myVar2)
spew.Fprintf(os.Stderr, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
spew.Fprintf(os.Stderr, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
See the Index for the full list convenience functions.
Sample Formatter Output
Double pointer to a uint8:
%v: <**>5
%+v: <**>(0xf8400420d0->0xf8400420c8)5
%#v: (**uint8)5
%#+v: (**uint8)(0xf8400420d0->0xf8400420c8)5
Pointer to circular struct with a uint8 field and a pointer to itself:
%v: <*>{1 <*><shown>}
%+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)<shown>}
%#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)<shown>}
%#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)<shown>}
See the Printf example for details on the setup of variables being shown
here.
Errors
Since it is possible for custom Stringer/error interfaces to panic, spew
detects them and handles them internally by printing the panic information
inline with the output. Since spew is intended to provide deep pretty printing
capabilities on structures, it intentionally does not return any errors.

Dump displays the passed parameters to standard out with newlines, customizable

following features over the built-in printing facilities provided by the fmt
package:
* Pointers are dereferenced and followed
* Circular data structures are detected and handled properly
* Custom Stringer/error interfaces are optionally invoked, including
on unexported types
* Custom types which only implement the Stringer/error interfaces via
a pointer receiver are optionally invoked when passing non-pointer
variables
* Byte arrays and slices are dumped like the hexdump -C command which
includes offsets, byte values in hex, and ASCII output
The configuration options are controlled by an exported package global,
spew.Config. See ConfigState for options documentation.
See Fdump if you would prefer dumping to an arbitrary io.Writer or Sdump to
get the formatted result as a string.

The custom formatter only responds to the %v (most compact), %+v (adds pointer
addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb
combinations. Any other verbs such as %x and %q will be sent to the the
standard fmt package for formatting. In addition, the custom formatter ignores
the width and precision arguments (however they will still work on the format
specifiers not handled by the custom formatter).
Typically this function shouldn't be called directly. It is much easier to make
use of the custom formatter by calling one of the convenience functions such as
Printf, Println, or Fprintf.

[![Build Status](https://travis-ci.org/pmezard/go-difflib.png?branch=master)](https://travis-ci.org/pmezard/go-difflib)
[![GoDoc](https://godoc.org/github.com/pmezard/go-difflib/difflib?status.svg)](https://godoc.org/github.com/pmezard/go-difflib/difflib)
Go-difflib is a partial port of python 3 difflib package. Its main goal
was to make unified and context diff available in pure Go, mostly for
testing purposes.
The following class and functions (and related tests) have be ported:
* `SequenceMatcher`
* `unified_diff()`
* `context_diff()`
## Installation
```bash
$ go get github.com/pmezard/go-difflib/difflib
```
### Quick Start
Diffs are configured with Unified (or ContextDiff) structures, and can
be output to an io.Writer or returned as a string.
```Go
diff := UnifiedDiff{
A: difflib.SplitLines("foo\nbar\n"),
B: difflib.SplitLines("foo\nbaz\n"),
FromFile: "Original",
ToFile: "Current",
Context: 3,
}
text, _ := GetUnifiedDiffString(diff)
fmt.Printf(text)
```
would output:
```
--- Original
+++ Current

// SequenceMatcher compares sequence of strings. The basic
// algorithm predates, and is a little fancier than, an algorithm
// published in the late 1980's by Ratcliff and Obershelp under the
// hyperbolic name "gestalt pattern matching". The basic idea is to find
// the longest contiguous matching subsequence that contains no "junk"
// elements (R-O doesn't address junk). The same idea is then applied
// recursively to the pieces of the sequences to the left and to the right
// of the matching subsequence. This does not yield minimal edit
// sequences, but does tend to yield matches that "look right" to people.
//
// SequenceMatcher tries to compute a "human-friendly diff" between two
// sequences. Unlike e.g. UNIX(tm) diff, the fundamental notion is the
// longest *contiguous* & junk-free matching subsequence. That's what
// catches peoples' eyes. The Windows(tm) windiff has another interesting
// notion, pairing up elements that appear uniquely in each sequence.
// That, and the method here, appear to yield more intuitive difference
// reports than does diff. This method appears to be the least vulnerable
// to synching up on blocks of "junk lines", though (like blank lines in
// ordinary text files, or maybe "<P>" lines in HTML files). That may be
// because this is the only method of the 3 that has a *concept* of
// "junk" <wink>.
//
// Timing: Basic R-O is cubic time worst case and quadratic time expected
// case. SequenceMatcher is quadratic time for the worst case and has
// expected-case behavior dependent in a complicated way on how many
// elements the sequences have in common; best case time is linear.

// By default, the diff control lines (those with *** or ---) are
// created with a trailing newline.
//
// For inputs that do not have trailing newlines, set the diff.Eol
// argument to "" so that the output will be uniformly newline free.
//
// The context diff format normally has a header for filenames and
// modification times. Any or all of these may be specified using
// strings for diff.FromFile, diff.ToFile, diff.FromDate, diff.ToDate.
// The modification times are normally expressed in the ISO 8601 format.

Testify - Thou Shalt Write Tests
================================
[![Build Status](https://travis-ci.org/stretchr/testify.svg)](https://travis-ci.org/stretchr/testify)
Go code (golang) set of packages that provide many tools for testifying that your code will behave as you intend.
Features include:
* [Easy assertions](#assert-package)
* [Mocking](#mock-package)
* [HTTP response trapping](#http-package)
* [Testing suite interfaces and functions](#suite-package)
Get started:
* Install testify with [one line of code](#installation), or [update it with another](#staying-up-to-date)
* For an introduction to writing test code in Go, see http://golang.org/doc/code.html#Testing
* Check out the API Documentation http://godoc.org/github.com/stretchr/testify
* To make your testing life easier, check out our other project, [gorc](http://github.com/stretchr/gorc)
* A little about [Test-Driven Development (TDD)](http://en.wikipedia.org/wiki/Test-driven_development)
[`assert`](http://godoc.org/github.com/stretchr/testify/assert "API documentation") package
-------------------------------------------------------------------------------------------
The `assert` package provides some helpful methods that allow you to write better test code in Go.
* Prints friendly, easy to read failure descriptions
* Allows for very readable code
* Optionally annotate each assertion with a message
See it in action:
```go
package yours
import (
"testing"
"github.com/stretchr/testify/assert"
)
func TestSomething(t *testing.T) {
// assert equality
assert.Equal(t, 123, 123, "they should be equal")
// assert inequality
assert.NotEqual(t, 123, 456, "they should not be equal")
// assert for nil (good for errors)
assert.Nil(t, object)
// assert for not nil (good when you expect something)
if assert.NotNil(t, object) {
// now we know that object isn't nil, we are safe to make
// further assertions without causing any errors
assert.Equal(t, "Something", object.Value)
}
}
```
* Every assert func takes the `testing.T` object as the first argument. This is how it writes the errors out through the normal `go test` capabilities.
* Every assert func returns a bool indicating whether the assertion was successful or not, this is useful for if you want to go on making further assertions under certain conditions.
if you assert many times, use the below:
```go
package yours
import (
"testing"
"github.com/stretchr/testify/assert"
)
func TestSomething(t *testing.T) {
assert := assert.New(t)
// assert equality
assert.Equal(123, 123, "they should be equal")
// assert inequality
assert.NotEqual(123, 456, "they should not be equal")
// assert for nil (good for errors)
assert.Nil(object)
// assert for not nil (good when you expect something)
if assert.NotNil(object) {
// now we know that object isn't nil, we are safe to make
// further assertions without causing any errors
assert.Equal("Something", object.Value)
}
}
```
[`require`](http://godoc.org/github.com/stretchr/testify/require "API documentation") package
---------------------------------------------------------------------------------------------
The `require` package provides same global functions as the `assert` package, but instead of returning a boolean result they terminate current test.
See [t.FailNow](http://golang.org/pkg/testing/#T.FailNow) for details.
[`http`](http://godoc.org/github.com/stretchr/testify/http "API documentation") package
---------------------------------------------------------------------------------------
The `http` package contains test objects useful for testing code that relies on the `net/http` package. Check out the [(deprecated) API documentation for the `http` package](http://godoc.org/github.com/stretchr/testify/http).
We recommend you use [httptest](http://golang.org/pkg/net/http/httptest) instead.
[`mock`](http://godoc.org/github.com/stretchr/testify/mock "API documentation") package
----------------------------------------------------------------------------------------
The `mock` package provides a mechanism for easily writing mock objects that can be used in place of real objects when writing test code.
An example test function that tests a piece of code that relies on an external object `testObj`, can setup expectations (testify) and assert that they indeed happened:
```go
package yours
import (
"testing"
"github.com/stretchr/testify/mock"
)
/*
Test objects
*/
// MyMockedObject is a mocked object that implements an interface
// that describes an object that the code I am testing relies on.
type MyMockedObject struct{
mock.Mock
}
// DoSomething is a method on MyMockedObject that implements some interface
// and just records the activity, and returns what the Mock object tells it to.
//
// In the real object, this method would do something useful, but since this
// is a mocked object - we're just going to stub it out.
//
// NOTE: This method is not being tested here, code that uses this object is.
func (m *MyMockedObject) DoSomething(number int) (bool, error) {
args := m.Called(number)
return args.Bool(0), args.Error(1)
}
/*
Actual test functions
*/
// TestSomething is an example of how to use our test object to
// make assertions about some target code we are testing.
func TestSomething(t *testing.T) {
// create an instance of our test object
testObj := new(MyMockedObject)
// setup expectations
testObj.On("DoSomething", 123).Return(true, nil)
// call the code we are testing
targetFuncThatDoesSomethingWithObj(testObj)
// assert that the expectations were met
testObj.AssertExpectations(t)
}
```
For more information on how to write mock code, check out the [API documentation for the `mock` package](http://godoc.org/github.com/stretchr/testify/mock).
You can use the [mockery tool](http://github.com/vektra/mockery) to autogenerate the mock code against an interface as well, making using mocks much quicker.
[`suite`](http://godoc.org/github.com/stretchr/testify/suite "API documentation") package
-----------------------------------------------------------------------------------------
The `suite` package provides functionality that you might be used to from more common object oriented languages. With it, you can build a testing suite as a struct, build setup/teardown methods and testing methods on your struct, and run them with 'go test' as per normal.
An example suite is shown below:
```go
// Basic imports
import (
"testing"
"github.com/stretchr/testify/assert"
"github.com/stretchr/testify/suite"
)
// Define the suite, and absorb the built-in basic suite
// functionality from testify - including a T() method which
// returns the current testing context
type ExampleTestSuite struct {
suite.Suite
VariableThatShouldStartAtFive int
}
// Make sure that VariableThatShouldStartAtFive is set to five
// before each test
func (suite *ExampleTestSuite) SetupTest() {
suite.VariableThatShouldStartAtFive = 5
}
// All methods that begin with "Test" are run as tests within a
// suite.
func (suite *ExampleTestSuite) TestExample() {
assert.Equal(suite.T(), 5, suite.VariableThatShouldStartAtFive)
}
// In order for 'go test' to run this suite, we need to create
// a normal test function and pass our suite to suite.Run
func TestExampleTestSuite(t *testing.T) {
suite.Run(t, new(ExampleTestSuite))
}
```
For a more complete example, using all of the functionality provided by the suite package, look at our [example testing suite](https://github.com/stretchr/testify/blob/master/suite/suite_test.go)
For more information on writing suites, check out the [API documentation for the `suite` package](http://godoc.org/github.com/stretchr/testify/suite).
`Suite` object has assertion methods:
```go
// Basic imports
import (
"testing"
"github.com/stretchr/testify/suite"
)
// Define the suite, and absorb the built-in basic suite
// functionality from testify - including assertion methods.
type ExampleTestSuite struct {
suite.Suite
VariableThatShouldStartAtFive int
}
// Make sure that VariableThatShouldStartAtFive is set to five
// before each test
func (suite *ExampleTestSuite) SetupTest() {
suite.VariableThatShouldStartAtFive = 5
}
// All methods that begin with "Test" are run as tests within a
// suite.
func (suite *ExampleTestSuite) TestExample() {
suite.Equal(suite.VariableThatShouldStartAtFive, 5)
}
// In order for 'go test' to run this suite, we need to create
// a normal test function and pass our suite to suite.Run
func TestExampleTestSuite(t *testing.T) {
suite.Run(t, new(ExampleTestSuite))
}
```
