Testing technique is set of rules and approaches used to test an application or product within acceptable norms.
Various Testing Techniques are:
Static Testing
Dynamic Testing
- White Box Testing
- Black Box Testing
Next, we will have a detail look on Static Testing.
The process of executing a program or system with the intent of finding errors is referred as Dynamic Testing.
Further, Dynamic Testing is sub divided under this are:
- White Box Testing
- Black Box Testing
WHITE BOX TESTING
The following types of testing fall under the white box testing technique - Unit Testing, Integration Testing etc.
BLACK BOX TESTING
The following types of testing fall under the Black box testing technique - System Testing, Acceptance Testing etc.
Next, we understand difference between White Box and Black Box Testing.
WHITE BOX TESTING
- Structure & Design based Testing
- Program-Logic driven Testing
- Examines the internal structure of program
Following are the advatages of White Box Testing:
- High Code coverage – Exhaustive (thorough) path testing
- Program logic is tested
- Internal boundaries are tested
- Testing is algorithm specific
BLACK BOX TESTING
- Specification based Testing
- Business-Transaction driven Testing
- No concern to internal behavior and program structure
Following are the advatages of Black Box Testing:
- User’s perspective
- Focus on features, not implementation
- Big-picture approach
Next, we will discuss various phases of V MODEL. And the next one is UNIT TESTING
There are different set of Test Techniques, Test Environment Set up, and Test Approach to test different kind of Intra Module, Inter Module, and External Interface.
Intra Module Interface
Test Technique - White Box
Test Environment - Development Environment
Test Approach - Check for parameter, procedure, database updating etc
Inter Module Interface
Test Technique - Black Box
Test Environment - Isolated Development Environment or CIT Environment
Test Approach - Identify pre and post process to validate interface
External Interface
Test Technique - Black Box
Test Environment - Simulate (Production) Live Environment
Test Approach - Identify interfaces and validate against external system
Next is various Integartion Techniques.
