eslint-plugin-no-only-tests is an ESLint plugin that prevents committing or pushing code with accidentally left *.only statements in your tests. It automatically identifies instances of .only applied to test suites or individual tests (like Mocha's describe.only or Jest's it.only) within your JavaScript or TypeScript codebase. This enforced rule helps avoid running only a subset of tests in CI/CD environments or during team collaboration, ensuring consistent and complete test coverage.
