| # 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. | |
