Different types of software testing techniques help the developer to understand the functioning of the software at different phases of software development. In terms of quality, it has become essential for a developer to test the software for bugs before releasing it into the market. Establishing the right testing technique is essential to analyze and perform changes to the development of software at an early stage. The testing technique provides the differences between given input and expected output from this software. Continue to read ahead as we provide information related to different testing techniques that exist in the modern world.
1. Unit testing
These types of software testing techniques helps the developer gains the ability to carry out testing for individual source code units. There is a possibility for the developer to utilize one set or more of a computer program module that is together associated with usage procedure, operating procedure and control data.
2. Integration testing
Under this specific testing, the testing engineer combines two different individual software modules and creates a test group. This is only applicable after unit testing and before validation testing. The procedure utilizes the input modules available from the unit test and groups them into larger aggregates. It then carries out the integration of the input data and delivers the output that is ready for system testing.
3. Functional testing
These types of software testing techniques fall under quality assurance process. It bases the test on the specifications provided by the software component. It is a simple testing procedure, which utilizes the input of the software component and records the output.
4. System testing
This specific software testing is performed on a complete, integrated system to evaluate the compliance of the system with the specified requirements of the software. System testing is part of a black box testing. There is no requirement for the operator to possess knowledge on the code or logic of the software.
5. Stress testing
These types of software testing techniques are deliberately performed to determine the stability of the system and its supporting software. The system defines and determines the breaking points, usage limits, intended specifications, modes of failure and the standard usage range for stable operation. Reliability engineers often carry out the test under expected press specifications or under accelerated stress specifications.
6. Performance testing
A performance test evaluates the functioning of the software by detailed and component specification. It often measures the final measurable performance characteristics using a specific qualitative or quantitative procedure.
As there are different types of software testing techniques existing in the information technology category, it is necessary for a user to understand the importance of the procedure. They should be carrying out to test the functionality of the software before releasing it into the market. Such a process provides information related to the range of operation, system requirement and optimum performance under varying conditions. Providing this information to the user is necessary to achieve fruitful results by using the application. Reliability engineers and testing engineers carry out different forms and phases of testing during software development.
