What is the Importance of Software Testing? There is a stage in the full SDLC dedicated to software testing. Traditionally, done after the developer is done developing software - it is left to the test team to perform this test. It is, in my opinion, the most important part of the SDLC process.The reason this is so important is that it is a major factor in obtaining good quality software. Developing software that works and works well is main goal of the project, and test phase is where it is done.The software testing phase can be broken down into smaller steps, each with its own interests : Unit Testing - testing of each individual software components, to check that it works correctly isolation.System Testing - testing of the entire system as a whole, to ensure that all components work as expected.Regression Testing - testing the entire system to a predetermined list of tests, to ensure that the new changes will not affect existing functionality. It is important to upgrade and update software.
These are the main types of software testing and each of them is important. I believe there are three main reasons we do software testing.Software Test Results With Less MaintenanceThe purpose of software testing is to ensure good quality software. Good quality software means having fewer defects or problems, work well, and do what needs to be done. When you perform software testing as part of a development project, you are aiming to get and find all the problems in the system before release to end users.In perfect world, developers can create software that works first to go, and not have any issues. However, this does not happen often - the bug appears in the system and software testing stage was there to pick it up. If found before the release, that's great. If found after release, which means it will need to spend finding and fixing conduct more tests on it - all the while end users use software.The time taken to fix defects after software is released significantly more than testing phase. This is because the repair requires further evaluation, and should be aligned with each other or to schedule a maintenance release that the organization was founded. Getting it right the first time when you discharge it is almost always preferable approach.Good Software Testing Results With Improved User MoraleAs mentioned above, fix bugs in the system before release is preferred. Another benefit of doing this is the spirit and confidence in using the software increases. Why is this? Well, say Project A is completed but software testing is not done very well. The software works, but not very well, but still released to users. They started using it, and even do some things well, there are still outstanding issues so that some parts do not work as expected. This resulted in user frustration with the tool - which is not a good thing for the organization or project team. Defects can eventually fixed, but reduce the morale of users take the time to heal.
Alternatively, Project B is completed. They spend more time on software testing and when released, it will be far fewer defects. It took longer to produce, due to the increased focus on testing, but once users have it, it works well and they will be happy to test software.The efforts and decisions may be affected by the work of your organization, and other factors, but moral benefits to users high.Software Game Testing Products For software testing Requirements The final important reason is that it is used to match the software to requirements.Software built around user requirements gathered during the study phase of the project. Analysis phase defines what the software should do. The developer aims to build on these requirements, but the test phase to check that the requirements have been met.The test performed on functional requirements - such behavior is expected and what needs to be done. It checks that the software does what it is supposed to do, and nothing is done incorrectly or abandoned. We also evaluated the non-functional requirements - things like load times and other performance measures.What If We Do not Do Software Testing One question people may be wondering, what if we do not do software testing ? What if you only make software developers and released?
That is a choice - but I do not think it is a very good one.It depends on the developer actually creates a low defect software - which is highly unlikely. All developers (including me) think that their software is bug free, but in reality, the problem is always found.Releasing software without testing means there is a high risk of problems found, and The software does not really work. This will waste a lot of time and effort users while using it. This may actually result in more serious problems, such as security breaches, loss of data and summary corruption.In, the importance of software testing can be attributed to three areas - less maintenance, increased use moral, and meet the requirements. It makes high-quality software - that should be something we all aim for.
