Description: Yarn Test is a command used to run tests defined in the project. Yarn, a package manager for JavaScript, allows developers to manage dependencies and scripts efficiently. The ‘yarn test’ command is commonly used to execute automated tests, which are essential for ensuring that the code works as expected. This command looks in the project’s configuration file, typically ‘package.json’, and runs the defined test script. Tests can include unit tests, integration tests, and end-to-end tests, depending on the project’s setup. By using Yarn, developers can benefit from its speed and efficiency in dependency management, leading to a more agile and productive development environment. Additionally, Yarn offers features like parallel package installation and local caching, further enhancing the development experience. In summary, Yarn Test is a fundamental tool in modern development workflows, enabling teams to maintain code quality and facilitate early error detection.
