Parallel runner for Behat

neochief's picture

Hey guys!

Just want to let you know, that I've created a Behat extension, which allows parallel execution of tests. In most cases, using this extension should decrease test suite execution time a lot. For example, for my own project, it decreased execution time of full test suite from around 60 to 30 minutes (on my local machine).

Check it out and let me know what do you think.


Well done!

Error :

Problem 1
- The requested package shvetsgroup/parallelrunner could not be found in any version, there may be a typo in the package name.

Potential causes:
- A typo in the package name
- The package is not available in a stable-enough version according to your minimum-stability setting
