Difference Between

1) Positive & Negative test case

2) Verification & Validation

3) Static & Dynamic

4) Regression & Retesting

5) Smoke and sanity

6) Black Box & White Box

7) Alpha & Beta

1) Positive & Negative test case:

 Positive test case: - Test to check whether the system do what it is suppose to do.ie, checking for valid values only.

 Negative Test Case: - Test to check whether the system will do what it is not supposed to do.ie, checking for invalid values.

2) Verification & Validation:

 Verification: It is a set of activity which confirms that the software is created accordance to the specification

 Validation: Is a set of activity which confirms software is created is linked to user requirement or not

3) Regression & Retesting:

Retesting: Failed test case are executed to ensure that defect is really fixed

Regression: all passed test cases are executed on related module to verify that there is no injection of new defect to change in one of the module

4) Static & Dynamic:

Static: Reviewing artifacts rather that exciting code

Dynamic: Testing Perform by executing code by giving i/p and verify o/p

5) Smoke & Sanity:

Smoke: Is a simple test condition to ensure that the software is working properly at gross level so that further testing is done

Sanity: It perform to verify whether the application function according to specification or not

6)  White Box And Back Box:

White Box: It is done by developer. This require knowledge of internal structure and code of that     application Type of white box: 1) Statement 2) Decision3) Condition 4) path 5) loop

Black box: This is done by tester it mainly focus on functional requirement. By providing set of I/P and observe output. Black box type: 1) BVA 2)    Equivalence class partitioning      3) state transition

7) Alpha & Beta testing:

Alpha: It is done at developer side under controlled environment. Here developer is present

Beta: It is conducted at one or more customer site in live environment by end user .here developer is not present
