What are the stages in the software testing process?

Testing plays a vital role in the development of quality software. It refines the whole process, thus reducing the maintenance costs and ensuring that the software is error-free. It also provides better usability and enhanced functionality since the software meets all the market standards.

Stages of testing

1. Component testing: The components discussed here are simple entities such as functions, object classes, or maybe a coherent grouping of these entities. In this stage, these components are individually tested by the system developer to ensure that they execute flawlessly.

2. System testing: The individual components are integrated to create a complete system, and the system is tested for errors. Errors in this stage may result from unanticipated interactions between components and components interface problems. Testing at this stage also ensures that the system fulfills all the functionalIt is the description of the main services provided by the software. and non-functionalThese are the constraints imposed on the system and the indirect requirements that are fulfilled such as security etc. requirements.

3. Customer testing: This is the final stage after which the software is accepted to be used operationally. The software is tested by the software user rather than simulated test data. User testing might reveal errors in requirements and usability as testing with real users is different than that with test data.

Errors in these testing stages are resolved immediately as these stages are interlinked. Testing can move interchangeably between these stages to guarantee flexibility and rapid response to errors.
