Codeception: Trait not found when using @runInSeparateProcess

[ultimagriever]

What are you trying to achieve?

I'm trying to use PHPUnit @runInSeparateProcess to run a test in a separate process, I don't know if Codeception supports it.

What do you get instead?

Provide console output if related. Use -vvv mode for more details.

I'm trying to use PHPUnit @runInSeparateProcess to run a test in a separate process, I don't know if Codeception supports it.

No.

Current PHP and PHPUnit implementation of this behavior are pretty complex and unstable. That's why I'd not use it. By allowing this behavior we will need to rework the codebase to allow concurrent execution which still is not first-class citizen in PHP.

[chippyash]

I have the same issue. Using straight PhpUnit with @runInSeparateProcess works just fine. Using CodeCeption doesn't. This therefore indicates that CodeCeption is not, in some way, wrapping PhpUnit in stable/proper fashion

[Sieg]

Same here. I have planned to port everything I have to codeception, but there are a lot of tests which requires this separateprocess. :( Sad...

[seisenreich]

My team and I are using this @runInSeperateProcess annotation to test classes which execute PHPs header in our Code without the need of making a single test suite per test to run their tests together.
I don't think that sending headers with PHP and wanting to test this behaviour automated is something uncommon.

This is a key feature of PHPUnit and should therefore be supported in any framework building on top of PHPUnit which claims to have a kind of compatibility to PHPUnit in my humble opinion.

Best regards.
