API

assert $test

• message - Optional message to print for the assertion failure. Prints the actual test if not specified.

Tests the given expression using bracket notation. This is very similar to the built in test command, except that the an "assertion failed" message is printed to stderr upon failure.

Returns 0 if the test passes, or 1 if the test fails.

#!/usr/bin/env import
import assert@2.1.3

assert 1 -eq 2
# assertion error: 1 -eq 2

message="one does not equal two" assert 1 -eq 2
# assertion error: one does not equal two

assert_equal $actual $expected

Tests that the the actual value is equal to the expected value. Strings or numbers may be used interchangeably, since the = operator is used under the hood.

#!/usr/bin/env import
import assert@2.1.3

assert_equal foo bar
# assertion error: foo = bar

assert_exit $exit_code $command

Tests that the given command exits with the specified exit_code.

#!/usr/bin/env import
import assert@2.1.3

# Passes
assert_exit 0 true

# This will fail
assert_exit 6 sh -c "exit 7"
# assertion failed: `sh -c exit 7` exited with 0, not 6
