Infinite improbability testing – execute all tests in parallel (Anton Angelov, Bulgaria)

100000 tests executed under half an hour – sounds like a myth? Well, we made it, and I’m going to tell you a story how we got there. Through surveys, we discovered that many companies desire to utilize the benefits from parallel tests execution to optimize their software development process. However, they struggle with the process. Lack of available tooling, documentation, tests data arrangement/deletion, handling E2E tests specifics like browsers, emulators, etc. We were one of this companies. Because of that, we created an open-source tool for the job. Throughout the presentation, you will find statistics where, depending on the type of the tests, the tests execution can speed up from 4- 40 times which makes the run of the 100000 tests possible for 27 minutes.

It will be shown how to utilize the tool, its various features and where/when it is appropriate to use it. Also, you will find example solutions to most of the common challenges in executing tests in parallel. We believe that in the near future the parallel tests execution will be a necessity, much like unit tests or continuous integration now. This will be one of the pillars for the companies to improve their competitiveness and effectiveness.
