Frequently asked questions

What is an AI test case generator?

An AI test case generator is a software tool that uses artificial intelligence and machine learning to automatically create, execute, and maintain software test scenarios based on application behaviour or natural language inputs.

How do self-healing tests work?

Self-healing tests use machine learning algorithms to detect changes in application user interface elements, such as ID shifts or class name updates, and automatically adjust the test scripts so they do not fail unnecessarily.

Are AI test generators suitable for beginners?

Yes, many AI test generators feature codeless interfaces and natural language processing, allowing manual testers and product owners to write and execute robust automated tests without advanced programming skills.
