About the talk

But They Worked Locally ... How To Fix Flaky Tests On The Real Device Cloud - Daniel Paulus | Senior Software Engineer at Sauce Labs

The most challenging aspect of running tests on a real device cloud is the multitude of possible failures. It could be that the test is inherently flaky, because writing reliable UI tests is hard. It could be that the app actually has a bug. It is possible that there is an unreliable device on the cloud or on very rare occasions, you could have discovered a bug in the real device platform. What you will see is that your tests always passed on your local device(s) but suddenly fail on the cloud.

Attendees of Daniel’s presentation will leave with:

- Effective ways of analyzing test failures using real-world examples

- An understanding of common pitfalls

- Some good advice to make your tests work again
