Cyclic @depends runs out of memory

[leonardor]

I try to run codecept.phar version 2.5.1 with -g flag to select only the tests I am interested in to run.

After I run the command like that:

php codecept.phar run functional -g group_name -vvv --debug

and it just outputs this after a long time:

Codeception PHP Testing Framework v2.5.1
Powered by PHPUnit 5.7.27 by Sebastian Bergmann and contributors.
Running with seed:

[Groups] group_name
PHP Fatal error:  Allowed memory size of 1073741824 bytes exhausted (tried to al
locate 262144 bytes) in phar://C:/workspace/laravel/workbench/application/codecept.phar/src/Codeception/Test/Cest.php on line 160

There are 48 files in the functional suite folder and as far as I understand it first parses the annotations of all tests and then identifies the groups, and at one point it gets stuck at one test and method in particular.

I tried to remove one by one the test files and see which causes the problem and I have identified it. There is a test which has a method that is 51 characters long. If I remove one character and if its name fits exactly 50 characters long the suite runs perfectly.

I can't figure out if this is a Codeception problem of a PHPUnit problem.

I have identified the real cause. That long method @depends on a previous method that also @depends on a method that should run after these two so there was a loop; the renaming just broke the chain of dependencies. Is there a validator that can identify when the chain of dependencies is broken?

Thank you!
