Setting Up PHPUnit tests for WP development on Windows

Question

I've been following the instructions in this article to try to set up some testing.

I got as far as this instruction bash bin/install-wp-tests.sh wordpress_test root 'mypass' localhost latest before I hit some problems.

I have git bash installed so the command ran, but I got this error when I runphpunit:

Fatal error: require_once(): Failed opening required '/tmp/wordpress-tests-lib/includes/functions.php' (include_path='.;C:\php\pear') in C:\Program Files (x86)\Ampps\www\dev\robinandrews-wp\wp-content\plugins\plugin-testing\tests\bootstrap.php on line 14

Not sure that include path looks right? If that's the prop how can I change it, and what to?

Any help much appreciated.

The output from the above command is:
