Explaining about Software testing and Components?

- Software Testing is a process of test an application/project with the intention of finding defects.

- Software Testing means combination of Verification and Validation.

              " Software testing= Verification + Validation "

1.Verification:

                       - It is a process of verify developing  project is right or not.

                       - It is also called as " Static Testing ".

                       - It is to check whether s/w conforms the specifications and it is done by management people and technical people and developers.

2.Validation:

                       - It is a process of validating the developed project is right or not.

                       - It is also called " Dynamic Testing ".

                       - Verification is the process of checking the project is right or not.but validation is to check whether the software meets the customer expectation.this is done by test engineers(Quality Analyst's) and Client-side people.

1.Static testing:

               - It's a process of verifying that developing product is right or not.It is also called as "Module Testing or Component testing".

               - It will be carried out with the help of Reviews and Walk-through's. 

Static Testing 
             - Reviews
                        1.management Review
                        2.Technical Review
                        3.Code Review
                        4.Formal Review
                        5.Informal Review

              - Walk Through's

2.Dynamic Testing:

               - It is process of validating the developer's system is right or not.It is also called as "clear-box testing or structural testing".

                   - It will be carried out with the help of White-Box Testing and Black-Box Testing.

Dynamic Testing
           - Unit Testing
           - Integration Testing
           - System Testing
           - User Acceptance Testing.
Note:
1. White-box Testing = Unit Testing + Integration Testing.
2. Black-box Testing = System testing + User Acceptance Testing.
