In the next few sections, we will discuss the static and dynamic techniques. But most static analysis tools can only scan source code, which is problematic. Manual testing 31 what is static testing and dynamic. Software testing is a process carried out to check and confirm the delivery potential of the software. The testing of software is an important means of assessing the software to determine its quality. In this procedure, a set of predecided inputs are fed into the software and the output produced is measured against the expected results. Hence dynamic testing is to confirm that the software product.
What is the difference between static and dynamic testing. Static application security testing sast can be thought of as testing the application from the inside out by examining its source code, byte code or application binaries for conditions indicative of a security vulnerability.
