In the software development life cycle (SDLC), testing is the phase where developers check whether the software satisfies the specific requirements, needs, and expectations of the customer by testing for bugs, defects, and errors. Testing tools help testers to find issues in their products before the users do, ultimately resulting in better quality software.
There are many types of testing, some of which include unit testing, integration testing, load testing, and usability testing. Some tools focus on just one category, while others provide comprehensive coverage.
Within the testing sphere, shift-left and automation are becoming increasingly important. Looking ahead to the future, artificial intelligence (AI) and machine learning (ML) may play a key role by allowing organizations to automate even further.
