Both Mocha and Puppeteer allow you to set timeout values, and a long timeout value can avoid triggering an error, if some action simply requires a long time to run. At the top of the test suite, we used this Mocha function:
this.timeout(10000);
That gives 10 seconds for every test case. If you want to use a longer timeout, increase that number.
The puppeteer.launch function can take a timeout value in its options object. By default, Puppeteer uses a 30-second timeout on most operations, and they all take an options object with a setting to change that timeout period. In this case, we've added the slowMo option to slow down operations on the browser.
