What are you trying to achieve?

I am developing a Yii2 module that is designed for applications with both frontend and backend components, requiring separate test configurations. To simplify configuration management, I created a base configuration file, codeception.base.yml, which contains common settings such as database, Yii2 modules, and paths. Then, I extended this base configuration in two separate codeception.yml files for the frontend and backend.

However, I noticed that when I define the params: - .env in the base configuration file, Codeception ignores it during test execution. The .env file is not loaded, which causes the tests to fail. If I explicitly define the params: - .env in each extended configuration file, then everything works as expected.

What do you get instead?

The tests fail to run correctly because the environment variables from .env are not being loaded from the base configuration file. If i run with debug-d enabled there is not call to any params loader.

Code Example

Here is an example of my setup:

codeception.base.yml:

paths:
    log: tests/_output
    data: tests/_data
    support: tests/_support
    envs: tests/_envs

modules:
    enabled:
        - Yii2:
            configFile: 'config/test.php'
        - Db:
            dsn: 'mysql:host=127.0.0.1;dbname=testdb'
            user: 'root'
            password: '%MYSQL_PASS%'
            populate: false
            cleanup: false

params:
    - .env

frontend/codeception.yml:

extends: ../codeception.base.yml
# i also set here the custom config file for yii2 module
paths:
    tests: frontend/tests
    output: frontend/tests/_output
    support: frontend/tests/_support
    envs: frontend/tests/_envs
    

backend/codeception.yml:

extends: ../codeception.base.yml
# i also set here the custom config file for yii2 module
paths:
    tests: backend/tests
    output: backend/tests/_output
    support: backend/tests/_support
    envs: backend/tests/_envs

When params: - .env is only defined in codeception.base.yml, it is ignored. But if I add it to each codeception.yml like this, the tests run successfully:

params:
    - .env
