What is Testing Why It is Necessary?

Testing is necessary to increase the quality of the project. Testing is most time consuming, but a crucial activity of a software project.

It is vital to the success of new system. For making the project reliable and Error Free, the complete project and product must be tested in a systematic and organized way.

DEFINITION OF TESTING

(According To Hetzel)
“Testing is the mechanism of establishing sureness that a program or product does what it is supposed to do.”

(According To Glen Meyers)
“Testing is the mechanism of executing a program or product with the intent of finding errors.”


WHY NEED OF TESTING

It is remarkably performed for one of the two reasons: -

1. Bug Detection

2. Improvement belonging to quality

 Testing is needed not always for improving product and project quality but also for improving company quality. Without testing company can’t grow at the upper level.

Testing is needed for almost all the organization which wants to grown up easily. Testing is needed for properly understand the fault errors in software during its development phases.

Testing is necessary in software development. It always ensures the users satisfaction and reliability of affecting software.

Below given the example which clears why testing is necessary: -

For Example if a company works on some long projects, and delivers those projects to the client without doing the proper testing, and after delivering the projects to client if client found some big bugs on the projects, than at that time it is the ashamed for company.

And obviously that client never comes back for having testing of their projects so it’s harm to company and apart from loss company quality is also decreasing so testing is needed.

Conclusion: -
At last we conclude it’s a fact that, when specific person starts checking commodity which is prepare by some other person, there are definitely 99% chances that checker and observer will discover some problem with the system. So it clears testing is needed.

Difference Between Verification And Validation With Example?

Verification and Validation example is also given just below to this table.                Verification               Validation 1. Verification is a static practice of verifying documents, design, code and program. 1. Validation is a dynamic mechanism of validating and testing the actual product. 2. It does not involve executing the code. 2. It always involves executing the code. 3. It is human based checking of documents and files. 3. It is computer based execution of program. 4.  Verification uses methods like inspections, reviews, walkthroughs, and Desk-checking etc. 4.  Validation uses methods like black box (functional)  testing, gray box testing, and white box (structural) testing etc. 5.  Verification  is to check whether the softwar...

Regression Testing with Example and Strategies

Regression Testing is done to ensure that fixed bug does not affect the remaining functionality of the modules and also the functionality of the same module. In short you can say regression testing  is always done to verify that modified code does not break the existing functionality of the application and works within the requirements of the system. Regression Testing Example  For Example there are three Modules in the Project named Admin Module, Personal Information, and Employment Module and suppose bug occurs in the Admin Module like on Admin Module existing User is not able to login with valid login credentials so this is the bug.  Now Testing team sends the above - mentioned Bug to the Development team to fix it and when development team fixes the Bug and hand over to Testing team than testing team checks that fixed bug does not affect the remaining functionality of the other modules (Admin, PI, Employment) and also the functionality of ...

What Is Functional Testing Explain It with Example?

Functional testing means testing the application against business requirements. Functional testing is executed using the functional specifications given by the client or by the design specifications according to use cases given by the design team. Role of functional testing is to validating the behavior of an application. Functional testing is more important because it always verifies that your system is fixed for release. The functional tests define your working system in a useful manner. In functional testing tester has to validate the application to see that all specified requirements of the client whatever we have said in SRS or BRS have been incorporated or not. Functional testing  is always concentrating on customer requirements and whereas the Non-Functional testing is always concentrating on customer expectations. Functional and Non Functional Test Cases Functional test cases target business goals and non functional test cases target performance, resource...
