When its about test automation, Jenkins offers plugins that assist you in running test suites, collecting dashboard results, and providing data on failures.

Functional testing automation can be implemented using a variety of tools and techniques. Some common methods include:

• Record and playback tools: These tools allow you to record your manual test cases and then play them back automatically. This can be a good way to automate simple, repetitive tests.
• Scripted testing tools: These tools require you to write scripts in a programming language to automate your test cases. This gives you more flexibility to automate complex tests, but it requires more programming knowledge.
• Model-based testing tools: These tools allow you to create a model of your application and then generate test cases from the model. This can be a good way to automate complex tests, but it can be time-consuming to create the model.
