Software Testing - Test Completion Criterion
Software testing is a very important phase of the software development lifecycle (SDLC). However, it is very critical to determine when the testing can be considered to be completed. The test completion not only involves execution of all the test cases and evaluation of the test outcomes but it also includes other activities. All these are carried out to ensure that the software is extensively tested, and is of high quality.
What is Software Test Completion Criterion?
The test completion criterion as known as TCC consists of the minimum checklists which need to be satisfied so that the software is considered ready to be released to the production environment. Those checklists or situations are well defined in the test plan. All the project stakeholders should be on the same page while deciding upon the test completion criterion.
The test completion criterion is critical to ensure that uniform and effective testing processes are being followed. It is distinct, feasible, applicable, and limited in duration. It gives more visibility on the goals and objectives of testing a software. It is reviewed and modified on a regular basis during the complete software development process, thereby making it relevant and attainable. The conditions of the test completion criterion are determined by the items listed below −
- The number of test cases that run.
- The percentage of code coverage.
- The number of bugs resolved.
- The potential risks to the software.
Let us take an example of e-commerce application, where the test completion criterion is comprised of the parameters listed below −
- Running of all the available test cases.
- Obtaining a code coverage of eighty-five percent.
- All critical defects are fixed.
- Minimizing the risk to an acceptable level.
Software Test Completion Criterion for Various Test Levels
The test completion criterion for various test levels are listed below −
- Unit Testing − It is the first level of testing done by the developers. It includes successful execution of all the unit test cases. The code coverage percentage should be as per the given requirements. Every high priority bug should be identified and resolved.
- Integration Testing − It is the second level of testing. It includes successful execution of all the integration test cases. The software should function as per the requirements. Every high priority bug should be identified and resolved.
- System Testing − It is the third level of testing. It includes successful execution of all the system test cases. The software should function to fulfill the customers needs. Every high priority bug should be identified and resolved.
- User Acceptance Testing − It is the final level of testing which is sometimes done at the customers site. It verifies whether the software meets customers requirements, and if it can be deployed to the production environment.
Importance of Software Test Completion Criterion
The importance of the software test completion criterion are listed below −
- The test completion criterion ensures that the testing procedure is extensive and exhaustive.
- The test completion criterion helps to mitigate all the potential risks in the software.
- The test completion criterion ensures that the software is delivered on time and there are no additional expenses.
