It's a common approach to filter specs with tags, grep or any other techniques, however we had a gotcha here before - a new session is created for every spec file which takes some time, especially for mobile tests.

Over the last few years a lot of new testing frameworks have evolved that provide different capabilities but also come with certain limitations. While tools like Selenium are often seen as slow and flaky and others like Cypress.io or Puppeteer are hyped as the future in the testing space. In reality all tools have their own use cases, have different levels of support and are based on a completely different architecture. Comparing them is rather useless as it ends up comparing apples with oranges. In larger test suites flakiness and race conditions can happen using all of these tools so that we can safely say that up to this point none of them (including WebdriverIO) has found the ultimate solution for world /(domin|autom)ation/.

We are pleased to announce that we now have support for CucumberJS in WebdriverIO V5!!!! This has been a great challenge for the project committers so we're all very thankful for the time and effort they put into this.
