Multiple utils-module for several test types

[Belco90]

I would definitely like to have this feature, but I understand that this is not trival to implement.

We have two different types of tests: unit and integration. Both use a different custom render function and re-export testing-library stuff. Each type has its own module.

Hey @rosczja! I'm moving here your petition for allowing to set a list of modules into utils-module.

This is a feature that will take time to implement and won't happen soon to be honest. However, I'd like you to give us more info about your setup since it might be possible for you to achieve what you want with the current plugin version + ESLint overrides.

Can you share more details about how you differentiate between those two types of tests? Do they have different filename suffix? Or perhaps are located under different folders?

[rosczja]

Hey @Belco90 , thank you very much.

Yes, we differentiate between those two types by filename suffix. So you are right, I could try to use overrides. Will definitely try this out.

[Belco90]

Alright. Assuming you use .unit and .integration suffixes for differentiate them, you could do something like this:

// .eslintrc
{
  "plugins": [/* other plugins */, "testing-library"],
  "extends": [/* other extends */, "plugin:testing-library/react"],

  "overrides": [
    {
      // unit tests
      "files": ["**/?(*.)+(spec|test).unit.[jt]s?(x)"],
      settings: {
        "testing-library/utils-module": "unit-test-utils"
      }
    },
    {
      // integration tests
      "files": ["**/?(*.)+(spec|test).integration.[jt]s?(x)"],
      settings: {
        "testing-library/utils-module": "integration-test-utils"
      }
    }
  ],
};

However, if you have your tests files identified properly, I'd leave the new Aggressive Reporting doing its thing and run eslint-plugin-testing-library only against your test files (no matter if unit or integration).

Let me know if any of these options work for you!

@Belco90 I've seen this kind of snippet mentioned a couple of times (About using the file extension to separate files); Maybe it's worth documenting somewhere (like a FAQ or as part of the readme)

[Belco90]

@gndelia we added it to our README!

• Run the plugin only against test files
• Troubleshooting

🤦‍♂️ for me

[rosczja]

Hi @Belco90 , thanks again. Works for me, too.

[Belco90]

@rosczja I'm glad it works! I'm closing the issue then.
