What is Functional Testing? As part of the Quality Assurance process, functional testing is a testing prerequisite for assessing precisely how the system functions. A system comprises of several components that must all work individually, and also mutually, for robust functioning. These aspects must be verified through in-depth functional testing. In functional testing, each component is first tested to confirm if its desired output is as per code, and then doubly checked to ensure that…
What happens typically in a Functional Testing scenario? In this back-box testing type, various functions are put under test with certain inputs, where their output is checked and measured for accuracy and effectiveness. Software Functional Testing is very much critical for software application development, as it helps to check the software’s dependency much before it is finally deployed for the users or across the IT infrastructures. Weighed on similar lines, Performance Testing and Functional Testing…
Functional Testing Vs Performance Testing: Differences between Performance Testing, Load Testing and Stress Testing were explained with examples in our last tutorial. Software Testing covers a wide range of areas where any verification or validation of software functionality can occur. Occasionally, non-functional aspects become less concerning the functional aspects. They are not performed practically; simultaneously during software testing. Quick difference between Performance Testing and Functional Testing Sl NOFunctional TestingPerformance Testing1To verify the accuracy of the software with definite…
Myopia means nearsightedness. If you write functional tests, you likely suffer from functional test myopia. You focus on your expected outcome and your test coverage, but you miss the big picture. We all know the joke about one night with a guy on his knees under a streetlamp. As he’s fumbling around, a passerby notices him. “Sir,” says the passerby, “What are you doing down there?” “I’m looking for my wallet,” replies the guy. “Where…
