Question 1

How to set up eslint-plugin-jest-formatting with an existing ESLint config?

Accepted Answer

Add 'jest-formatting' to the plugins array in your .eslintrc and extend 'plugin:jest-formatting/recommended' for quick setup, or manually enable specific rules under the rules section. The README provides JSON examples for both approaches.

Question 2

What's the difference between eslint-plugin-jest and eslint-plugin-jest-formatting?

Accepted Answer

eslint-plugin-jest focuses on test logic, best practices, and error detection in Jest suites, while eslint-plugin-jest-formatting is solely for formatting aspects like spacing. They complement each other, as noted in the Related Projects section.

Question 3

Does eslint-plugin-jest-formatting work with TypeScript projects?

Accepted Answer

Yes, it should work with TypeScript if ESLint is configured to parse TypeScript files, such as using @typescript-eslint/parser. However, the plugin itself is JavaScript-agnostic and doesn't have built-in TypeScript-specific rules.

Question 4

Can I use it alongside Prettier without conflicts?

Accepted Answer

Yes, but you may need to configure Prettier to ignore Jest formatting rules or adjust ESLint rules to avoid clashes, as both tools can enforce formatting. It's common to use ESLint for code quality and Prettier for style, with careful overlap management.

Question 5

How to disable a specific padding rule in eslint-plugin-jest-formatting?

Accepted Answer

In your .eslintrc, set the individual rule to 0 or 'off' under the rules section, or avoid using the strict config if it's too aggressive. For example, add 'jest-formatting/padding-around-describe-blocks': 0 to disable that rule.
