How To Develop A Quality Product ?

Right from the beginning to end, every developer knows the process of  developing  a software or an application, but still there happens a lack when it comes to programming and delivering quality products to customers. Get to know the software engineering process discussed below, which is well known in the name of Waterfall model.

This model has got numerous issues as it is tested only at the end of the project. If the  design is not done as per the requirements, then the implementation and verification done will go in vain and the software gets totally useless to the client.

In order to avoid these mistakes there came many models like prototype, spiral, etc., but finally a stable model named V-model was introduced and 90% of companies using this model feel their business to be quite successful. You can see the model flow below.

As you see, the model above has testing in each and every phase, so that people may not miss anything and the requirements will not be deviated anymore.

Only after testing we move to the next steps and testing itself has the process called STLC ( Software Testing LIfe Cycle ). The steps of software testing life cycle is described below:

Software Testing Life Cycle (STLC) :

Requirement   Stage    ——>    Test Plan —–> Test Design —-> Test Execution —> Defect Tracking —-> Bug Reporting —> Regression /   Testing  .

This makes your testing very stable and you may provide 99% bug free software to the clients.

There are two major testing methodologies included, which is Black box testing and white box testing.

Black Box testing :

This is the functional testing done externally without testing the internal parts of the code and this can be done by a software test engineer

White Box testing  :

This is the security testing used to validate internal parts of the software such as programming and determine the proper output.

Here unit testing and integration testing can be done by the developer. System testing and acceptance testing can be done by the tester.

Test Case Model

Look at the sample test case model below, which includes the following information

  • TCD —> Test case ID
  • Test Case
  • Usage
  • Impact
  • Positive/negative
  • Data to be used
  • Expected result
  • Trace Info
  • Comments
  • Pass/ Fail

Above all, you should have the RTM to track all that you have done with the project or product you have developed.

RTM is Requirement Traceability Management which is used to cross check whether the test cases have meet all the requirements specified for the project.

Hope the above mentioned things would greatly help you in developing a quality product.
