Is it possible to run PHP tests on ci.gitlab.com ??
Gitlab CI is basically a script runner. If you can run the tests from the shell, you can make gitlab-ci execute them as well. (As an example, this is what one of our CI jobs do: 1. Compile, 2. Flash a micro controller with the compiled firmware 3. run an application that communicates the the target hw and performs automated testing)
So yes, short answer: it is possible. ‘php’ is also a command on shell.
