Can Gulp be integrated with testing tools like Mocha or Jest? If so, how would you do it?

Yes, Gulp can be integrated with testing tools like Mocha or Jest. To integrate Gulp with Mocha, you need to install gulp-mocha plugin and require it in your gulpfile.js. Then, create a task that uses the gulp.src method to get the test files and pipe them into the mocha function.

For Jest integration, there’s no official gulp-jest plugin. However, you can use Node’s child_process module to spawn a new process running Jest. In your gulpfile.js, create a task that calls child_process.spawnSync(‘jest’), passing any necessary arguments.
