The following table lists the points that differentiate QA, QC, and Testing.In simple words, testing is executing a system in order to identify any gaps, errors, or missing requirements in contrary to the actual requirements.
Make Decision Table In Software Testing Software In ContextIn the IT industry, large companies have a team with responsibilities to evaluate the developed software in context of the given requirements.
Moreover, developers also conduct testing which is called Unit Testing. In most cases, the following professionals are involved in testing a system within their respective capacities. The next two sections state when testing should be started and when to end it during the SDLC. However in Software Development Life Cycle (SDLC), testing can be started from the Requirements Gathering phase and continued till the deployment of the software. For example, in the Waterfall model, formal testing is conducted in the testing phase; but in the incremental model, testing is performed at the end of every incrementiteration and the whole application is tested at the end. The following aspects are to be considered for stopping the testing process. Make Decision Table In Software Testing Verification And ValidationThe following table highlights the differences between verification and validation. Early testing saves both time and cost in many aspects, however reducing the cost without testing may result in improper design of a software application rendering the product useless. However diagnosing and fixing the errors identified during proper testing is a time-consuming but productive activity. However iterative or incremental approach as a development life cycle model may reduce the dependency of testing on the fully developed software. It is possible that all paths have been tested by the team but occurrence of complete testing is never possible. There might be some scenarios that are never executed by the test team or the client during the software development life cycle and may be executed once the project has been deployed. Make Decision Table In Software Testing Free Even IfNo one can claim with absolute certainty that a software application is 100 bug-free even if a tester with superb testing skills has tested the application. This myth relates to Time, Cost, and Requirements changing Constraints. However the test strategy may also result in bugs being missed by the testing team. Testers responsibilities include the identification of bugs to the stakeholders and then it is their decision whether they will fix the bug or release the software. Releasing the software at the time puts more pressure on the testers, as they will be blamed for any error. Test automaton should be started when the software has been manually tested and is stable to some extent. Moreover, test automation can never be used if requirements keep changing. Thinking alternative scenarios, try to crash a software with the intent to explore potential bugs is not possible for the person who developed it. ![]() Although they are interrelated and to some extent, they can be considered as same activities, but there exist distinguishing points that set them apart.
