Codeception: Trait '_generated/*TesterActions' not found

[kickthemooon]

What are you trying to achieve?

Im trying to run a test,

What do you get instead?

Im suddenly getting this error Trait '_generated/*TesterActions' not found.

Details

When I go look under _generated the file *TesterActions is still there but its empty.
It happens when codeception tries to rebuild the class.

• Codeception version: 2.2.10
• PHP Version: 7.0
• Operating System: Windows 10 / Vagrant
• Installation type: Composer

class_name: SomeTestTester
modules:
    enabled:
        - REST:
            url: https://domain.com/api
            depends: PhpBrowser
            part: Json
        - \Helper\ConfiguratorHelper
        - Db
        - Asserts

I have the feeling that it has something to do Line seperation between windows and linux
but im not sure.

I found that I had the same issue. Whenever I ran codecept run <test> or codecept build the contents of the AcceptanceTesterActions file was deleted, resulting in an error from the file in which it was used.

I have a similar setup to the one you described above:

Codecept version: 2.4.1
PHP Version: 5.6
Operating System: Windows 10 / Vagrant
Installation type: Composer

Confusingly the issue went away when I restarted my physical machine (rather than the virtual machine). As far as I can tell I did not change anything else between the restart and the running of the tests. I wish I could offer more help on this issue as I have experienced this problem before, but can't remember how it was resolved before!

[johannesschobel]

did you run codecept build in order to re-generate the helpers and traits?

[aricl]

Yes, that was the reason that I ran codecept build

Very mysterious issue. Looks like it's somehow related to Vagrant and Windows. Unfortunately, I don't use either of them so I don't think I can reproduce or fix it. Could you try to investigate it further?

[kickthemooon]

Im using --no-rebuild to bypass this issue but would really love to know what the real cause is.

I suspect it has something to do with LF for linux line breaks and CRLF for windows line breaks
because I recently installed git again and something got messed up with my line breaks after which the issue started to occur unfortunately I didn't have time to investigate it deeper.

Hello, I have the same issue I put a namespace and run build but the codeception cannot find my trait.

[exteon]

Ditto. Probably different error, same result: for me, using @runTestsInSeparateProcesses annotation for a unit test results in:

  [PHPUnit\Framework\Exception] Fatal error: Trait '_generated\UnitTesterActions' not found in .../tests/_support/UnitTester.php on line 21

do we have the fix? I got the same issues on 2.5.x version

[DanielRuf]

Same seems to happen on run.

Imo run should never rebuild anything. But it does when multiple envs are used for example. See https://github.com/Codeception/Codeception/issues/5500

We have this issue on macOS so this is not a platform specific issue.

I'm experiencing the same issue with v3.1.0 (Windows 10 & Ubuntu 18). Any work-around or solution available?

[alexatendios]

same issue

[alexander-ronin]

Same error. More than year Codeception can't fix it?

It's not the issue of codeception, it's just issue with autoload, just read this https://getcomposer.org/doc/04-schema.md#autoload

Afaik this is not an autoload issue and also happens with a phar and normal setups which use a normal composer setup with a working autoloader.

I had a sort of workaround, codeception prepends '_support' prefix directory for that class, so I changed '_support' dir settings to './' in codeception.yml, and the class was found, though I had tests in the root directory './', when I changed it to 'tests' - the default, it was somehow found along despite _support prefix. But along I had some other issue an incorrect number of parameters passed to Cest.php so I removed all codeception.yml files I had in any directory if it could be related to the first problem, and it removed also the second problem.

Edit: the second problem though after investigation might be due to having tests and vendor in the root directory, considers also tests parent Cest.php being a test, thus the tests cannot be at the vendor dir level

Turns out this indeed is autoloading issue. To confirm this I've first simply tried to add require_once('/path/to/trait/AcceptanceTesterActions.php'); to AcceptanceTester class.. and it worked.

The solution for us was to add this line to the global _bootstrap.php file.

\Codeception\Util\Autoload::addNamespace('_generated', YOUR_ROOT_DIR . '/path/to/tests/_support/_generated/');

Hope this helps.

[ptsakyrellis]

I have this error too, but it's not solved with autoloading or the solution provided by @tomolas

It happens as soon as I add a module in my suite config file, the trait generated is an empty file.

(codeception v. 4.0.2)

It oddly disappeared after rebooting my computer.
