NPM Script and CLI | Bondar Academy

Lesson Summary

This lesson focuses on optimizing the execution of Playwright tests using npm scripts to simplify command line operations. Key Concepts Command Line Interface: Initially discussed how to execute Playwright tests using the command line. Long Commands: Commands can be lengthy, especially when specifying test files and projects. Environment Variables: Additional parameters can be passed, making commands even longer. Creating npm Scripts To avoid typing long commands repeatedly, you can create npm scripts in the package.json file: Navigate to the scripts section in package.json . Create a script with a descriptive name, e.g., "po page object test chromium" . Paste the command you want to execute. To run the script, use: npm run po page object test chromium Chaining Scripts You can also create scripts that call other scripts: Define a new script, e.g., "po test all" . Use the && operator to chain commands. Example: npm run po test chromium && npm run po test firefox This allows for flexible execution of multiple tests and commands, enhancing convenience and efficiency in your testing workflow. In summary, using npm scripts can significantly streamline the process of running Playwright tests, making it easier to manage and execute commands.
