Levels of Quality Assurance in Software
There are different levels of quality assurance in software development, each with its unique purpose and scope. Here, we’ll discuss the four main levels of quality assurance and their associated testing stages.
1. Unit Testing
Unit testing is the first level of quality assurance and involves testing individual units of code to ensure they operate as intended. This testing should be performed by the developer as they write the code.
Unit testing is done with the help of a testing framework that simulates the environment in which the code will run.
The goal of unit testing is to catch errors early in the development process. Because unit testing ensures that each component of a software application functions correctly on its own, any issues can be addressed before they impact how the system works as a whole.
2. Integration Testing
Integration testing follows unit testing and tests how different units of code work together. The goal of integration testing is to ensure that the integrated code works as intended, that the units communicate correctly, and that the system operates as a whole.
Integration testing is often performed using automated testing tools that simulate the interactions between units of code. Integration testing can also involve manual testing in situations where human judgment is necessary to ensure that the software behaves as expected.
3. System Testing
System testing is performed after integration testing and tests the software as a whole. The goal of system testing is to ensure that the entire system works as intended, that it meets all of its functional requirements, and that it is easy to use.
System testing is typically performed manually, although automated testing tools can also be used. The testing is often done in a simulated environment that resembles the system’s intended usage environment.
4. Acceptance Testing
Acceptance testing is the final level of quality assurance and tests the system with the goal of ensuring that it meets the user’s requirements and needs. This testing is typically performed by the end-user or a representative of the user.
Acceptance testing is done with the end goal of determining whether the software is ready for release. When acceptance testing is complete, the software is deemed acceptable for release if it meets all of the user’s requirements and needs.
Quality Control Tests List in Software
Quality control tests must be performed throughout the software development process to ensure that the software meets the expected quality standards. Below is a list of quality control tests that you should consider implementing in your software development process:
| Test Type | Description |
|---|---|
