eslint-plugin-mocha

What is eslint-plugin-mocha?

eslint-plugin-mocha is an ESLint plugin that provides linting rules specific to Mocha, a popular JavaScript test framework. It helps enforce best practices and coding standards for Mocha tests, ensuring consistency and reducing common errors.

What are eslint-plugin-mocha's main functionalities?

Disallow exclusive tests

This rule disallows the use of exclusive tests (e.g., `describe.only` and `it.only`) to prevent accidentally skipping other tests.

module.exports = { "rules": { "mocha/no-exclusive-tests": "error" } };

Disallow skipped tests

This rule warns against the use of skipped tests (e.g., `describe.skip` and `it.skip`) to ensure that all tests are being run.

module.exports = { "rules": { "mocha/no-skipped-tests": "warn" } };

Enforce test case titles

This rule enforces that test cases have valid descriptions, ensuring that test titles are meaningful and descriptive.

module.exports = { "rules": { "mocha/valid-test-description": "error" } };

Disallow synchronous tests

This rule disallows synchronous tests, encouraging the use of asynchronous tests to avoid blocking the event loop.

module.exports = { "rules": { "mocha/no-synchronous-tests": "error" } };

Limit the number of top-level suites

This rule limits the number of top-level suites in a test file, promoting better organization and structure of tests.

module.exports = { "rules": { "mocha/max-top-level-suites": ["error", { "limit": 1 }] } };
