Introduction to Types of Test Case
Types of test cases can be defined as the differentiation in the usage of the test cases on each of the testing stages in the software testing life cycle. For example, a few of the commonly used test case types are ‘functionality test cases’ for functional testing on the new requirements, ‘Integration test cases’ for testing the integration modules of the application, ‘database test cases’ for the execution of validating the databases, ‘unit test cases’ for unit testing that is performed by the developers in the dev environment, and ‘user interface test cases’ for testing the graphical user interface.
Types of Test Case
Given below are different types of Test Cases:
1. Functionality Test Case
Test case functionality is used to determine whether the interface of the application works with the rest of the system and its users. The tests reveal that the software has succeeded or failed to perform the functions. The cases include a type of black-box evaluation, which uses the code under review for its structure, requirements or user background.
It allows the experiments to be performed without the need for access to the software’s function or internal structures. The QA team usually writes operational test cases because the work is part of normal Quality assurance processes. You can write and run when a first function is provided for testing in the development. They can be written beforehand if each tester has access to the requirements to help manage the development.
2. User Interface Test Case
The aim of this GUI test is to check the GUI according to client requirements. Detailed design report and GUI mockup screens discuss the intended GUI of the device. The GUI Testing involves the width of the buttons and the fields in which all text, tables, and columns are aligned in the display. It also validates the interface of the request, validates that the site does not differ when choosing different menu items and lists. After the mouse has moved to the menu or sub-menus, the configuration stays the same.
3. Unit Test Case
The testing is referred to as unit testing for a particular software component or module. This usually happens by the developer and not by the tester, because the program design and implementation need thorough knowledge. The design of test drivers or test harnesses may also be appropriate.
4. Integration Test Case
The testing of all merged modules is called integration testing in order to verify the combined functionality after integration. Usually, the modules are program modules, individual programs, network client and server applications, etc. It type of test is particularly important for client/server and systems distributed.
5. Performance Test Case
The terms ‘ pressure ‘ and ‘ load ‘ testing are sometimes used interchangeably. Performance checks are carried out to decide if the device meets the performance requirements. To do this analysis, various charging methods and quality are used.
6. Security Test Case
Cases of safety tests help ensure that the software restricts activities and permissions where necessary. Such test cases are created to protect data where and when it needs protection. For penetration testing and other forms of safety-based tests, protection test cases are used. The emphasis on security test cases is often authentication and encryption. The security staff usually writes and executes this assignment.
7. Database Test Case
Database test cases analyze what is taking place in the background. The UI is clean and all appears to work but where is all this information going? the database tables, and the stored procedures in order to write such test cases. Many SQL queries are used by the test team to build test cases in the database. Database assessments are used to check that the programmer writes the code in such a way that the data are kept consistent and secure.
Example:
- Has the device stored the input data in the database?
- Unauthorized users may not access or update the data of the client.
8. Usability Test Case
Functionality analysis is done to check functionality. The app flexibility is checked to see whether new users can easily understand the software or not and if a user is confused at any point proper support is recorded. In principle, this experiment checks machine navigation.
Example of Test Case:
| Scenario | Test Step | Expected Result | Actual Outcome |
| Make sure the area of input will handle up to 10 characters. | Login to 10 characters’ request and password. | All 10 characters should be appropriate to the request. | All 10 characters are approved. |
| Make sure that the area of input will take up to 8 characters. | Login to 8 characters for request and password. | The application should not recognize all 8 characters. | All 11 characters are approved. |
Conclusion
The technology test types listed above are only a test element. In all types of projects, however, all research methods are not used. Covered a number of trials that are primarily used in the life cycle of research.
