Static and Dynamic tests: know the difference

Software failures are a constant for developers. To a lesser extent, they can only represent minor problems in running a system. In more severe cases, a bug or vulnerability could lead to exposure of user data and private company information.

These problems cause billionaire losses annually. But they are not just caused by the security risks that a malfunctioning system has. They are also the result of lost productivity and poor use experience. To go pass by them, companies adopt various testing strategies to make their development process more secure.

Want to know more about two of the most famous? Keep following and discover the differences between static and dynamic testing!

Main characteristics of a Static test

Static software analysis, also known as whitebox, works directly with the code of a tool. In this case, the components of a tool are checked without running the product. Whether through an automated tool or manual testing, the main purpose of this technique is to identify programming errors such as:

  • Bad practices;
  • Syntax errors;
  • Security flaws.

Static analysis helps IT managers identify all lines of code that were poorly written when creating software. All execution, processing and display paths of values ​​are examined. As a result, more common errors are discovered faster.

Main characteristics of a Dynamic test

Dynamic testing can be employed in addition to static analysis. This type of approach views software as a “black box” (hence the popular name “blackbox”) and works primarily with the information that is entered into the data input and output routines. In addition, items such as:

  • The response time;
  • Application performance;
  • The ability of software to adapt to different environments;
  • The functional behavior.

Many companies adopt dynamic analysis because it allows for more subtle problems to be identified. No matter how complex, the chances of a bug going through static analysis and dynamic analysis without being tracked is considerably low. In this way, dynamic testing can provide more security and reliability to the final product.

Making softwares more reliable

Static and dynamic analysis are among the ways to look for more quality and secure software. Although they have different backgrounds, both can be brought into the development environment. This can increase the company’s ability to deliver products with fewer errors and security issues.

Because static testing is done at an early stage of development, it typically comes at a lower cost than dynamic analysis. On the other hand, a dynamic test can be performed faster. In both cases, the analysis methods are highly complex, capable of easily verifying large systems.

These procedures can be applied to any systems development company. Hand in hand with good development practices, they help to considerably reduce the amount of holes and vulnerabilities in a product.
