In which cases is it necessary to automate application testing?

Automation of application testing is necessary in the following cases:

• During frequent code changes to quickly verify regressions and prevent errors.
• For repetitive tests that are difficult or time-consuming to perform manually (e.g., regression testing).
• When testing large volumes of data or complex scenarios where manual testing is inefficient.
• To ensure stability and quality of the product when scaling the team and project.
• When integration and system testing are required, where it is important to verify component interactions.

Automation helps accelerate the testing process, improve its accuracy, and reduce human error.
