Software Testing Overview
As a good software tester, you must design scripts, test cases and implement them to calculate the outcomes of different methods. For that purpose you need to know about test case and its objective, methods, levels and approaches.
Test case contains several set of conditions used to decide whether the software application is working good or not. It can be either positive or negative.
Objective of Testing
To check if the application meets the customer needs and requirements, and also guarantee the perfection and value of the application.
Methods of Testing
Software testing contains two popular methods; they are white box testing and black box testing. In white box testing, the test cases are mainly designed for internal structure of the program, so that here we consider the algorithm or internal code of the program. In black box testing, the tester no needs to have any familiarity about the algorithm or code of the program. Here we just test the working condition and functionality of the system.
Levels of Testing:
- Unit Testing
- Integration Testing
- System Testing
In unit testing the components or various units of the application are verified to check the functionality of the program code. In integration testing, verification is fully concentrated through integrating the various modules of the application. I system testing the whole application is verified for both system and functional requirements to test the behavior and function of the application at different levels.
Approaches of Testing
- Top-down Approach
- Bottom-up Approach
In top-down approach the upper level components are tested, whereas in bottom-up testing approach the lower level components are tested.
