When running tests, it's sometimes helpful to see verbose output from a test even when it succeeds. This can be useful to compare to a failure on another system to determine the relevant differences between the systems. Add support for reading an environment variable, LFS_DUMP_TEST_OUTPUT, that if set to a nonempty string causes the verbose test output to be printed. Continue printing verbose output automatically if an assertion fails.

# Simple shell command language test library.
|
|
#
|
|
# Tests must follow the basic form:
|
|
#
|
|
# begin_test "the thing"
|
|
# (
|
|
# set -e
|
|
# echo "hello"
|
|
# false
|
|
# )
|
|
# end_test
|
|
#
|
|
# When a test fails its stdout and stderr are shown.
|
|
#
|
|
# Note that tests must `set -e' within the subshell block or failed assertions
|
|
# will not cause the test to fail and the result may be misreported.
