Prerequisite – Software Testing
1. Re-Testing :
In Software Testing, Re-Testing refers to the testing again of a module to ensure that the bug is fixed. This means it confirms the test cases that failed in the final execution are passing after the errors/defects are fixed.
Process of Re-Testing is as follows –
- At first an error is detected in any module of the application.
- Then it undergoes for correction/modification by the developer.
- After the developer has solved and tested issue again, it is called Re-Testing.
2. Sanity Testing :
In Software Testing, Sanity Testing refers to the testing performed after receiving a software build, with minor changes in code, or functionality, to ascertain that the bugs/errors have been fixed and no further issues are introduced due to these changes.
Process of Sanity Testing is as follows –
- A software build is received first.
- Determine that the proposed functionality works roughly as expected after changes.
- If sanity test fails, the build is rejected.
- If sanity test passes, it is passed for further testing.
Difference between Re-Testing and Sanity Testing :
|1.||Re-Testing is carried out to check and confirm that the test cases that failed in the final execution are passing after those errors/defects are solved.||Sanity Testing is carried out to check and confirm that the functionalities are working perfectly after minor functionality/bug fixes or any changes.|
|2.||Defect verification comes under Re-Testing as a part.||Defect verification does not come under Sanity Testing as a part.|
|3.||Re-Testing is performed before start of Sanity Testing and Regression Testing.||Sanity Testing is performed before Regression Testing and after Smoke Testing.|
|4.||Test cases can not be automated for Re-Testing.||Sanity Testing is often executed manually.|
|5.||Re-Testing can be performed with the previously used test cases. Means test cases can be reused.||Sanity Testing can be performed without test cases with domain knowledge.|
|6.||Priority of Re-Testing is higher than Sanity Testing.||Priority of Sanity testing is lower than Sanity Testing.|
|7.||Before start of testing, test cases for Re-Testing cannot be obtained.||Test cases for Sanity Testing can be obtained from obtained from the functional specification, manuals, and defect reports in regards to corrected problems.|
