OpenTest is an open-source functional test automation framework that can be used to test web apps, mobile apps, and APIs. It is free and open-source. OpenTest focuses on mainstream automation practices and scalability. OpenTest is a feature-reach tool which requires very little to no programming skills and can handle almost any type of functional testing automation project. Keywords are high-level building blocks that hide the complexity of the technology and allow you to create concise, readable, and maintainable tests. No programming skills are required. Run multiple test sessions simultaneously, with only limited hardware resources. Once you have exhausted your local machine(s), you can spin up additional test actors in the cloud. To cover more complex scenarios, JavaScript code can be embedded naturally anywhere in your keyword-driven test. You can run multiple tests over the same set of data records.
