When working on a project, you may need to use different types of testing frameworks to verify and validate your software. Testing frameworks are sets of guidelines, tools, and libraries that help you automate, organize, and execute your tests. For instance, unit testing frameworks like JUnit or NUnit are used to test the smallest units of code, such as functions, methods, or classes, in isolation. Integration testing frameworks like TestNG or Cucumber are used to test how different units of code interact and work together. Lastly, performance testing frameworks like JMeter or Gatling are used to test how the software performs under different loads, stress, and scenarios. In this way, these frameworks help you ensure your software is functional, reliable, compatible, consistent, scalable, responsive, robust, and efficient.
