Dynamic verification, also known as experimentation, dynamic testing or, simply testing. - This is good for finding faults (software bugs). Static verification, also known as analysis or, static testing - This is useful for proving the correctness of a program. Although it may result in false positives when there are one or more conflicts ...
Static testing is often implicit, like proofreading, plus when programming tools/text editors check source code structure or compilers (pre-compilers) check syntax and data flow as static program analysis. Dynamic testing takes place when the program itself is run.
Proponents cite that dynamic testing: can identify weak areas in the runtime environment; supports application analysis even when the tester cannot access the source code; can identify vulnerabilities that are difficult to find via static testing; can verify the correctness of static testing results; Critics cite that:
In computer science, static program analysis (also known as static analysis or static simulation) is the analysis of computer programs performed without executing them, in contrast with dynamic program analysis, which is performed on programs during their execution in the integrated environment.

Unlike dynamic application security testing (DAST) tools for black-box testing of application functionality, SAST tools focus on the code content of the application, white-box testing. A SAST tool scans the source code of applications and its components to identify potential security vulnerabilities in their software and architecture.
Dynamic program analysis is the act of analyzing software that involves executing a program – as opposed to static program analysis, which does not execute it. Analysis can focus on different aspects of the software including but not limited to: behavior , test coverage , performance and security .
Dynamic stretches are done to warm up before a workout and static stretches are done to cool down. Stretching reduces injury risk, relieves sore muscles and increases flexibility.
Such final external validation requires the use of an acceptance test which is a dynamic test. However, it is also possible to perform internal static tests to find out if the software meets the requirements specification but that falls into the scope of static verification because the software is not running.
