Software Testing – 8 reasons

Software Testing – 8 reasons on why testing might be critical to product development life cycle and on how to product a great software

Generally in software development organization, company follows certain rules and regulation to make software. The developers follow some models to develop effective software. There are some models which are effectively used in software development process such as, waterfall model, spiral model, V model, Agile model etc. The most common model used is the waterfall model.

Different phases of waterfall model are:

So we can see as per the model fist is requirement analysis, where the developer have to analyze the requirement for software development. It may be software requirement, hardware requirement and anything as per the need. Second one is design phase where one team has to design the software as per the need of a client. Then come implementation where the developer implements the software if it is well prepared. And after that the testing phase which we will discuss below. And the last one is maintenance phase where the company have to provide service to client and fix the issues if arise in future.

Now what is testing? It is a process where the developer will check the software properly as it is designed as per the requirement or not. Different types software testing is there such as:

a. Unit testing
b. Integration testing
c. System testing
d. User acceptance testing
Etc…

As per the need of the project developer can choose to do software testing and make good report for the development process. Some testing are done at the end-user side, such as user acceptance testing.
So now question is why it is needed?

It is because:

1. To maintain the good quality software product.
2. Make the software bug and error free.
3. Provide the software to client as per the requirement.
4. Check the functionality and error and resolve it before installing into server.
5. Prevent defect migration. It is because the major error is done during requirement analysis, so error must be clear at the early stage.
6. Make the software economically strong. Because if the testing is done in best way the productivity will grow and the software will be economically strong in market.
7. A good software testing process will always keep the company reputation up in the market.
8. Most important thing is one tester is responsible to produce help documents, so that the user can easily use the software.

To understand the actual need of software testing we can take one example:

Suppose one company get project from a bank for making accounting software. The analyst of the company will gather the information from the client. After the requirement analysis the project manager and the team will prepare the SRS( software requirement specification). After that the developer will start working. If the developer will only develop the software and no testing in the project life cycle the then what will happen, when there is implementation in the bank, the bank employee will face problem when using it. And then bank will again report to company about the problem and the company will again try to fix the issue. So it will take a lot of time as well as money.

So if testing is done from the beginning then at the end company will produce good quality software.
