Test data helps us examine a software application and determine its functionality. The data used to test the features of a newly developed software program is simply, thus, called test data. It helps identify bugs provided it is properly designed. If the test data itself is faulty or of low quality, it will not do a good job identifying bugs and testing features. Needless to say, it will directly affect the quality of the software.
Generation of Test Data
Since the test data determines the quality of software testing and the development of the software application, you need to keep a close eye on its generation. Generation depends on the type of testing environment and software to be tested. It can be done in different ways:
Please keep in mind that test generation is quite complicated and requires time. In fact, in most cases, test generation takes a lot more time than the testing itself. However, it is mandatory that you pay close attention to this step because it will affect the quality of test data, thereby affecting the software quality.
Ensuring Quality of Test Data:
White Box Testing
For this type of testing, the test data can be extracted from the code directly. The quality can be ensured considering the following:
Black Box Testing
Since the tester cannot see the code in this case, certain criteria should be met in order to confirm quality of the test data.
Security testing revolves around protection against malicious content. The test data designed to test security software must satisfy the following:
Likewise, parameters to ensure the quality of test data vary with the software application. If the applications are complicated, going with automated test generation tools is the safest way to guarantee quality. As aforementioned, it is the quality of the test data that will influence the quality of the software. That is why putting it under the microscope is highly recommended.
