Software testing is the process of checking code lines to find errors. The process ensures an effortless coding function. Just like coding, software testing plays an integral role in software development. Furthermore, it enables web developers to look for mistakes without manual effort and brings more visibility to software quality assurance. In their article, Geeks for Geeks shares seven essential principles of software testing.
Principles of Software Testing
Experts believe there are seven principles of software testing:
- Showcasing the presence of defects
- Avoidance of exhaustive tests
- Early testing
- Defect clustering
- Pesticide paradox
- Testing as a context-based process
- The misconception of errors’ absence
Showcasing the Presence of Defects
Software testing discovers the presence of defects, but it cannot confirm the entire program is error-free. Testing can significantly reduce the number of errors but cannot guarantee complete eradication of them.
Avoidance of Exhaustive Tests
Software testing is not designed to test all known cases to ensure better quality assurance. It primarily tests certain cases and then assumes the overall result based on those tests. If the testing software was made to individually test every part of the coding, it would take significantly more time, effort, and resources.
Early testing is suggested in most cases to detect defects in the initial stage. The errors figured out in the initial phase of SDLC will cut down the costs compared to the later stages.
A small module can contain a considerable amount of errors. The Pareto principle states that 80% of software defects come from 20% of the modules.
A lot of programmers keep repeating the same tests to find new errors. The programming team needs to update the report on testing and keep a record of it.
Testing as a Context-Based Process
Testing largely depends on the context of the software. For instance, the testing of an e-commerce website is different from that of an android application.
The Misconception of Errors’ Absence
Many programs focus on creating error-free software and forget to think if it will suit customers’ requirements.
