Software Testing Types Every QA Should Know

The software testing process tests whether the application can run well in diverse environments and across various platforms. Usually, the testing project is categorized into functional testing and non-functional testing. Functional testing covers software functionality based on requirements and integration between components. Non-functional testing focuses on operational aspects like performance, load, and security. If you are applying for QA tester jobs in Chicago, be sure to learn about these types to answer in your interview assuredly.

Functional Testing

Unit testing, integration, and acceptance testing are some of the tests used to validate the application against the business requirements. Developers perform the first-level unit testing before passing it to the QA team. After each unit is validated, QA testers perform a system integration test to ensure that all units seamlessly integrate. The last phase of functional testing is acceptance testing, which checks for its usability.

Non-functional Testing

Performance testing tests the application under un-realistic load for a long time. This type of testing ensures that your application can be responsive even if there is a sudden spike in traffic. The rise in massive amounts of online data and the risk of cyber attacks necessitates applications' security testing.
