You’ve probably heard of parallel testing before, but the ability to multiply your testing power without multiplying your testing time seems something of a QA fantasy if you haven’t tried it yet. But once you experience parallel testing, you’ll never want to go back to life before it.
While there are probably hundreds of benefits from parallel testing, everyone will gain the value in different ways. In case you need to be convinced (or you need to convince your boss), we rounded up the top five advantages you can expect from parallel testing.
- More Browser Coverage – Take one test, run it across multiple browsers at once — that’s the beauty of parallel testing. If you’ve been running tests on different browsers one after the other, or even just skipping browser testing all together, you’ll realize how valuable parallel testing is after your first time trying it. Instead of only testing on one or two browsers, you can substantially increase your cross-browser coverage with parallel testing, hitting configurations you didn’t even realize were an issue. Plus, with CrossBrowserTesting’s broad selection of browsers, operating systems, and devices, you have seemingly endless options for checking the functionality for any and every user.
- Less Manual Testing – We’re not saying manual testing is a bad thing — in fact, it’s a pillar of a successful testing strategy. However, when you’re manually performing the same regression tests over and over on different browsers, you’re not making the most of your time. Not only is this boring, tedious work, you’re also risking human error and inaccurate test data by trying to repeat the same tests. Parallel testing allows you to repeat these tests in regression without worrying about skipping a step so you can be confident you’re reaching all the right parts of your application.
- Saves Valuable Time – Besides increasing test coverage, parallel also decreases the amount of time you’re actually spending on each test. Since you’re running multiple tests at the same time, rather than one after the other, you’re testing gets done in the fraction of the time it normally takes. In fact, just running 2 tests in parallel doubles your speed, and the more you run in parallel, the more time you save that can be spent elsewhere. This means you can redirect that energy to go back to performing the exploratory tests and looking at new parts of your application at while still meeting your deadlines.
- Improving the Development Workflow – Not only does parallel testing make your job easier, it allows for better communication between departments and improves the productivity of your entire team. By allowing for faster feedback and better reporting, parallel testing equips you with the ability to relay results from testing back to your team earlier in the development cycle. This means that parallel testing will be useful in your organization’s effort to shift left and implement Continuous Integration and Delivery practices that will get iterations to market faster and with fewer bugs.
- Go Scriptless – With CrossBrowserTesting, you now have even more ways to run your tests in parallel. With our Selenium grid, you can use your Selenium skills to write tests and run them in parallel. With Record & Replay, you can also achieve parallel testing with zero coding knowledge needed by executing a test manually then rerunning your suites across the browsers your choose. This means teams who are both new to automation and experienced in Selenium can benefit from the capabilities of parallel testing.
We could talk all day about how amazing parallel testing is, but don’t take our word for it. Whether you’ve automated 100 tests or 1, you can easily start running tests in parallel now to experience more code coverage with less time spent on manual regressions.
Try your hand at running a test in two browsers at once then take it to the next level by adding more, and witness pure testing magic right before your eyes.
