The purpose of Levels of testing is to make software testing structured/efficient and easily find all possible test cases/test scenarios at a particular level. In the SDLC model, there are personalized phases such as requirement meeting, analysis, coding, design, execution, testing, and deployment. These all phases go through the process of levels of testing in software testing.
There are many different testing levels that are used or help to check actions and performance for software testing. These testing levels are designed for missing areas and re-coded and re-linked between the development lifecycle states.
In general, mainly four levels of testing in software testing: Unit Testing, System Testing, Integration Testing, and Acceptance Testing.
Every testing level is very important testing for software testing but these four levels of testing are very important testing for software engineering.
This type of testing used tests for a single component or a single unit in software testing and this kind of testing is performed by the developer.
Unit testing is also the first level of functional testing. The primary goal of unit testing is to validate the performance of unit components.
Unit is the smallest testable portion of the system or application and the main aim is to test that each individual component or unit is correct in terms of fulfilling requirements and desired functionality.
The main advantage of this testing is that by detecting any errors in the software early in the day is that by doing so the team reduced software development risks, as well as time and money wasted in having to go back and take back fundamental defects in the program once it is nearly completed.
Integration testing means combining different software modules and phases and testing as a group to make sure that the integrated system is ready for system testing or not, and there are many ways to test how different components of the system function at their interface.
This type of testing is performed by testers and integration testing finds the data flow from one module to other modules.
System testing is most probably the final test to identify that the system meets the specification and criteria and it evaluates both function and non-functional needs for the testing.
System testing is allowing to check the system’s compliance as per the requirements and all the components of the software are tested as a whole in order to ensure that the overall product meets the requirements specified. It involves load, reliability, performance, and security testing.
System testing is a very important step as the software is almost ready for production in the market and once it is deployed it can be tested in an environment that is very close to the market/user-friendly environment which the user will experience.
The aim of acceptance testing is to evaluate whether the system complies with the end-user requirements and if it is ready for deployment.
The tester will utilize a different method such as pre-written scenarios and test cases to test the software and use the results obtained from these tools to find ways in which the system can be improved also QA team or testing team can find out how the the product will perform when it is installed on the user’s system.
Acceptance testing ranges from easily finding spelling mistakes and cosmetic errors to relatable bugs that could cause a major error in the application.
