Technical capabilities
This JavaScript testing framework is suitable for unit testing, where it is heavily influenced by other unit testing frameworks such as ScrewUnit, JSSpec, JSpec, and RSpec. This allows you to define test suites and individual test cases using a clear and readable syntax. Mocha has built-in support for testing asynchronous code, such as callbacks, promises, and async/await functions. The automated test framework provides mechanisms to handle async operations and ensure proper test completion. Mocha tests run in a sequential or serial order, which allows for flexible and accurate reporting while mapping uncaught exceptions to the correct test cases. The Playwright testing framework also offers powerful tools like Codegen, Playwright Inspector, and Trace Viewer.
