Static vs. Dynamic Testing

Software testing falls largely into two categories: static and dynamic. Both are valuable, but the scenario around the test being performed determines which method best fits.

Static testing is a testing technique that does not require the code to execute. This can include manual or automated reviews of the code, requirement documents, and document design, all of which are intended to catch errors in the code. Static testing is done in order to prevent errors during the early stages of development and can help locate errors undetected through dynamic testing methods. Reviews are an important facet of static testing and are the primary method for carrying out a static test. A review is a meeting or other process aimed at locating flaws and defects in the design of a program. Apart from physical walkthroughs of the code, there exist tools that automatically search for errors. These tools, such as CheckStyle and SourceMeter, can help developers adhere to standards in code and style.

Dynamic testing is a testing technique that checks the program’s behavior when code is executed. As the name suggests, it is intended to test the dynamic behavior of a software. This encompasses a vast majority of the testing methods we’ve discussed both in this class and on this blog. The two types of dynamic testing are white and black box testing, which are both techniques that I have discussed on this blog before. Dynamic testing ensures that a software is working properly during and after its installation, it makes sure that the software is stable, and it encourages consistency in the software’s functionality.
