Groups definition in (global) config lead to warning "Array to string conversion" in Run.php line 592.

[tzimpel]

What are you trying to achieve?

Use a global groups definition, as defined at https://codeception.com/docs/Customization#Group-Files.

This is required in order for infection/infection to work with codeception.

What do you get instead?

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

In Run.php line 592:
                                         
  [PHPUnit\Framework\Error\Warning (2)]  
  Array to string conversion

Provide test source code if related

1. Groups definition in config:

codeception.yml

groups:
  infection: [path/to/SomeTest.php]

Run codecept run -g infection

2. Overwrite when calling codecept run (this is what infection/infection does)

Run codecept run -g infection -o "groups: infection: [path/to/SomeTest.php]"
