Whether you're pursuing onsite or offshore QA, functional testing is an essential component of any test suite. It shows how effectively an application or system performs as a whole. Functional testing ensures that the customer's requirements will be met upon delivery, so the inputs are typically the specific business requirements.
Just getting started with functional testing for your product? Here are three commonly asked questions, along with answers from our expert QA engineers, to get you acquainted:
Sanity testing, which is usually undocumented and unscripted, covers the functionality of the product from end-to-end. It verifies that new functionality works, and that defects have been fixed.
Regression testing helps verify whether program behavior has changed or if fixed defects have re-emerged since previous tests. This type of testing is especially helpful after making a change to the program.
Usability testing ensures that the software interface is built to meet user expectations. Users expect a standard of efficiency and simplicity when using a product, and this type of testing measures how well the software meets that standard. Learn 7 essential tips for functional testing.
