React Unit Test Setup is an npm package designed to simplify the process of setting up unit testing in React.js projects. This package automates the installation of necessary dependencies and configuration files required for running unit tests with Jest and Enzyme.
To install React Unit Test Setup, run the following command in your terminal:
npm install reacttestmate-2.0 --save-dev
npm run setup-testsAfter installing the package, you can set up unit testing in your React.js project by running the following command in your project directory:
This command will automatically configure Jest and Enzyme by creating jest.config.js and src/setupTests.js files in your project directory.
The package provides two template files to configure Jest and Enzyme:
module.exports = {
// Indicates whether the coverage information should be collected while executing the test
collectCoverage: true,
// An array of file extensions your modules use
moduleFileExtensions: ['js', 'jsx', 'json'],
// A list of paths to directories that Jest should use to search for files in
roots: ['<rootDir>/src'],
// A list of paths to directories that Jest should use to search for files in
testMatch: ['**/__tests__/**/*.js?(x)', '**/?(*.)+(spec|test).js?(x)'],
// The glob patterns Jest uses to detect test files
testPathIgnorePatterns: ['\\\\node_modules\\\\'],
// An array of regexp pattern strings that are matched against all test paths, matched tests are skipped
testURL: 'http://localhost',
// This option sets the URL for the jsdom environment. It is reflected in properties such as location.href
verbose: true,
};
