# Tests support for either passing through or defining a default value for environment variable TEST_SHELL.
# (for test scripts that want to invoke shell scripts with a specified shell).

# Test if $TEST_SHELL, when placed in urchin's environment, is passed through to the test scripts.

Support for cross-shell testing added, via option `-s <shell>` and env. variable `TEST_SHELL`. * For tests that _source_ shell scripts: option `-s <shell>` now tells urchin to invoke test scripts with the specified shell (only shebang-less and `#!/bin/sh` tests scripts). * For tests that _invoke_ schell scripts: instruct users to write their tests to always invoke via environment variable `TEST_SHELL` (e.g., `$TEST_SHELL ../foo`), and invoke urchin with that variable defined as needed, e.g., `TEST_SHELL=ksh urchin ./tests`; urchin defaults `TEST_SHELL` to `/bin/sh`. See updated `readme.md` for details. 2014-10-17 17:16:12 -04:00			`#!/bin/sh`
