The second group 2x-chrome split all tests across 2 machines and executed them in Chrome browser. The loading element should become visible after at most 500ms, thus there is no point to wait for 4 seconds (the default command timeout) before the test fails. These commands allow you to define a test or test suite, respectively, and specify the code that should be executed when the test is run. Why is it shorter than a normal address?

You can use any string you like as the name of your test, as long as it accurately describes the purpose of the test. environment variables, which reporter to use, etc. It is important to note that running tests in parallel can be more complex than running them sequentially, as you need to ensure that your tests are independent and do not rely on shared state.

Now our test passes immediately: We have made our function 4 seconds faster and removed the idle time.
