No software is perfect. Even the most well-designed and extensively tested software will have some errors. As a software tester, it is your job to find these errors and report them so that they can be fixed.
In this blog post, we will discuss the principles of software testing and what every software tester needs to know. We will also provide tips for how to become a successful software tester.

13 Principles of Software Testing: What Every Tester Needs to Know
1. Software testing is a process, not a goal
Software testing is not a goal but rather a process that should be integrated into the software development process. In other words, you do not do testing at the end of the development process to “check” if the software is working properly.
Rather, testing should be done throughout the software development cycle to ensure errors are found and corrected as early as possible.

2. Software testing can never completely eliminate errors
As we mentioned before, software testing is a process, not a goal. This means that testing can never completely eliminate all errors from a software program or system. However, testing can significantly reduce the number of errors in a software program or system and make it more likely that any remaining errors will be found and corrected before the software is released.
3. Software testing should be done by someone other than the developer
One of the most important software testing principles is that it should be done by someone other than the developer. This is because developers are often too close to the software to see all of the errors. Having someone else test the software helps to ensure that more errors will be found and corrected.
4. Software testing should begin as early as possible in the development process
Testing should start in the early stages of the software development process. The sooner errors are found, the easier and cheaper they are to fix. Additionally, starting testing early will help to ensure that the software is of high quality when it is released.
5. Software testing should be conducted throughout the software development process
Software testing should not be seen as something that is done at the end of the software development process. Rather, testing should be conducted throughout the software development process. This will help to ensure that errors are found and corrected as early as possible.

6. Software testing can never completely eliminate all errors from a software program or system
One of the most important principles of software testing is that it can never completely eliminate all errors from a software program or system. This is because software testing is a process, not a goal.
However, software testing can significantly reduce the number of errors in a software program or system and make it more likely that any remaining errors will be found and corrected before the software is released.
7. Software testing should be planned and structured
Planning and structuring your testing efforts is essential to ensure that you are testing effectively. When planning your software testing, you should consider the following:
- What types of software tests are available?
- What are the pros and cons of every software test?
- What are software errors most likely to occur in my software?
- How can I design my software tests to detect these software errors effectively?
- What resources do I need to conduct my software testing (e.g., test tools, test environment, personnel)?
Answering these questions will help you create a testing plan that is tailored to your specific needs. Additionally, there are many software testing tools and resources available online that can help you plan and structure your testing efforts.
8. Software tests should be designed to detect errors, not to prove the software is error-free
One of the most important testing principles is that tests should be designed to detect errors, not to prove that the software is error-free. The goal of testing is not to find every possible error in the software; rather, it is to find enough errors to ensure that the software is fit for its intended purpose.
To accomplish this, software tests must be designed specifically to detect errors. This means that they should not be focused on proving that the software works; rather, they should be focused on finding situations where the software does not work as expected.
There are many different techniques that can be used to design software tests, and each has its own strengths and weaknesses. The most important thing is to choose the right technique for the software being tested and the errors that are most likely to be found.
9. Software testing should be conducted throughout the software development process, not just at the end
Software testing is a crucial phase of quality assurance. It should be conducted throughout the software development process, not just at the end. Testing can never replace good programming practices. It should be used to complement other software development activities, such as code reviews and static analysis.
Testing can be used to verify the functionality of a software program or system and detect errors.
10. Software testing is an essential part of quality assurance
Software testing is the process of verifying the accuracy and completeness of software. Testing can be done manually or automated. Software tests can be used to find bugs, performance bottlenecks, and security vulnerabilities.
Testing is an essential part of quality assurance and should be done throughout the software development process, not just at the end.
11. Software testing can never replace good programming practices
Testing can never replace good programming practices. Good programming practices, such as accurate comments, clear variable names, and consistent coding style, can help make the software more readable and maintainable.
They can also help make software easier to test. In addition, good programming practices can help prevent errors from occurring in the first place. However, no matter how good the programming practices are, testing is still necessary to ensure error-free software.
12. Software testing should be used to complement other software development activities, such as code reviews and static analysis
Software testing is just one part of software development. Other important activities include code reviews and static analysis. Usually, developers conduct code reviews to check each other’s code for errors. Static analysis is a process of analyzing software code without executing it. Both code reviews and static analysis can help find errors that software testing might miss.
Thus, testing is an essential part of software development, but it is not the only activity that should be done.
13. Defects cluster together
Software defects tend to cluster together. That is, if one software defect is found, other software defects will likely be found nearby. This is because the same underlying problems usually cause software defects.
As a software tester, you should be on the lookout for clusters of software defects. When you find a cluster of software defects, it is often a sign of a deeper problem that needs to be fixed.
Conclusion
As a software tester, you must understand software testing principles. By following these principles, you can become a successful software tester and help to ensure that software is of high quality. Thanks for reading!
