Software testing is operating the software under controlled conditions, to

• Verify that is we are developing the software in the right manner. Verify that it gives positive results.
•  Detect errors and Bugs.
• Validate that the system developed by us is the system desired by the client

 

Verification: Checking the software with respect to the specifications gathered.

There are two fundamental approaches for software verification. These are:-

1) Dynamic Testing/Dynamic analysis:

2) Static Testing / Static Analysis:     

 

 

Various methods of Dynamic Testing are:

1.  Unit Testing
2. Integration Testing
3. System Testing

Various methods of Static Testing

1. Reviews:  It goes through 6 steps which are: Planning, Kick off, Preparations, Review Meeting, Rework, and Follow-up.
2. Statistic Analysis Using Tools: Coding Standards, Code Metrics, Code Structure etc.

Validation: Checking the software with respect to customer’s expectations.

Various methods of validation are:

• Alpha Testing
• Beta Testing
