# Common utility file for Bazel shell tests
|
||||
#
|
||||
# unittest.bash: a unit test framework in Bash.
|
||||
#
|
||||
# A typical test suite looks like so:
|
||||
#
|
||||
# ------------------------------------------------------------------------
|
||||
# #!/bin/bash
|
||||
#
|
||||
# source path/to/unittest.bash || exit 1
|
||||
#
|
||||
# # Test that foo works.
|
||||
# function test_foo() {
|
||||
# foo >$TEST_log || fail "foo failed";
|
||||
# expect_log "blah" "Expected to see 'blah' in output of 'foo'."
|
||||
# }
|
||||
#
|
||||
# # Test that bar works.
|
||||
# function test_bar() {
|
||||
# bar 2>$TEST_log || fail "bar failed";
|
||||
# expect_not_log "ERROR" "Unexpected error from 'bar'."
|
||||
# ...
|
||||
# assert_equals $x $y
|
||||
# }
|
||||
#
|
||||
# run_suite "Test suite for blah"
|
||||
# ------------------------------------------------------------------------
|
||||
#
|
||||
# Each test function is considered to pass iff fail() is not called
|
||||
# while it is active. fail() may be called directly, or indirectly
|
||||
# via other assertions such as expect_log(). run_suite must be called
|
||||
# at the very end.
|
||||
#
|
||||
# A test function may redefine functions "set_up" and/or "tear_down";
|
||||
# these functions are executed before and after each test function,
|
||||
# respectively. Similarly, "cleanup" and "timeout" may be redefined,
|
||||
# and these function are called upon exit (of any kind) or a timeout.
|
||||
#
|
||||
# The user can pass --test_arg to bazel test to select specific tests
|
||||
# to run. Specifying --test_arg multiple times allows to select several
|
||||
# tests to be run in the given order. Additionally the user may define
|
||||
# TESTS=(test_foo test_bar ...) to specify a subset of test functions to
|
||||
# execute, for example, a working set during debugging. By default, all
|
||||
# functions called test_* will be executed.
|
||||
#
|
||||
# This file provides utilities for assertions over the output of a
|
||||
# command. The output of the command under test is directed to the
|
||||
# file $TEST_log, and then the expect_log* assertions can be used to
|
||||
# test for the presence of certain regular expressions in that file.
|
||||
#
|
||||
# The test framework is responsible for restoring the original working
|
||||
# directory before each test.
|
||||
#
|
||||
# The order in which test functions are run is not defined, so it is
|
||||
# important that tests clean up after themselves.
|
||||
#
|
||||
# Each test will be run in a new subshell.
|
||||
#
|
||||
# Functions named __* are not intended for use by clients.
|
||||
#
|
||||
# This framework implements the "test sharding protocol".
