Software testers have only one dream, and that is to find as many errors as possible, but they should remember that finding errors can help make any software more usable and higher quality. If the tester remembers some important points before starting the test, application testing is not rocket science. In this article, we will take a look at software testing techniques and techniques before starting to actually test any application. All of these techniques come from years of experience, so they are very effective and hope to help you.
Tips and tricks for testing any application:
1. Effective test cases: The first is to provide effective test cases, not more test cases. An effective test case is the most likely test case to find a defect. When writing test cases or self-checking, the tester must pay attention to the validity of the test by referring to the requirements document and understand which functions may go wrong.
2. Understand the complete application: When the tester has a complete understanding of the application, what has been implemented, what to expect and how to use the application efficiently, it is easy to find out where the application needs weaker and stronger testing .
3. Familiar with the functions of the application: testers should be familiar with all the functions of the application. What other function should be the most important? By doing this, the tester will have an idea what the priority of the test might be when time is limited.
4. Regression testing: When the application introduces new changes, it is strongly recommended that you perform regression testing to check whether the new changes affect any other functions. The tester should have a bunch of regression test cases to run each time a new change or feature is introduced to ensure that all the main features are working properly. It also makes basic testing fast and efficient.
5. Application small module division: When the tested application is divided into smaller unit modules, the coverage becomes more and more, the test becomes deeper and deeper, which helps testers find the most difficult errors and also helps better Understand the application.
6. Provide test cases to developers: If testers send test cases to developers, it is considered a good habit to verify that all important functions are developed correctly before releasing further test applications. It ensures that rework is minimized, because the most important part of the application is the responsibility of the developer himself.
7. Pay attention to performance testing: Performance testing is an important part of application testing, especially when applications require faster response time (such as banking applications or applications with timeout functions). Performance testing requires test data that the tester or developer provides to the tester for testing as required.
8. Practice stress and load testing: Testers should know the number of users that an application test can handle. It is important to perform stress testing to understand the bottleneck, otherwise the quality of the application will be questioned. The quality of an application can be determined by the number of users that can be provided at one time without interruption or unexpected results. It is very important to understand the limits, so thresholds can be applied to deal with this anomaly.
9. Think from different perspectives: applications can be used by different types of users; testers can find quality errors by thinking from different user perspectives. It can help avoid errors that will annoy some users or cause them some discomfort, and it will also make the application more flexible, more usable, and suitable for different users. Think about it, if a user who doesn't understand the application will use it without too much difficulty, making the application easy to use and understand.
10. Create test data: As mentioned above, when performing performance testing, testers need some test data to determine the performance of the application under test. Providing data in advance is a good practice because it is a time-consuming step that is often circumvented by testers in order to complete the test in a limited time. Testers can also get help with test data from developers.
11. Refer to the previous error list: If you are testing old applications or changes or new features introduced in the application, the previously broken features may be interrupted due to the new changes. It is best to take a look at the old bugs first and check them.
12. Don't underestimate exploratory testing: It is a well-known fact that exploratory testing finds the most errors in application testing. The tester should give some time to explore the test application and try to design random scenarios. He can also record these situations, and if an error is found, then the situation can be used as a test case for future use.
13. Write down your new opinions: If the tester records his opinions during the test, it will help to find different defects and understand the actual behavior of the test application. Testers must think beyond the limits of their thinking in order to find new defects that exceed the requirements but are important to the user.
14. Maximize test coverage: This can be done by breaking the application into small modules, and then further breaking it down into smaller units. It ensures that each area is covered, and each module has its own set of test cases. More coverage means more testing depth, thereby reducing the possibility of defects.
Conclusion: Remember the above tips, you can not only find quality errors, but also help make the application better and avoid errors. Use them to win recognition for your hard work.
