Maintenance Testing

What is Maintenance Testing?

Maintenance Testing is a type of software testing that verifies the application's functionality after the code changes that are done after the application is in the production environment. It ensures that the new code changes do not affect the existing functionality of the application. The testing team needs to execute the test cases and verify the results to ensure that the application's functionality is not affected by the code changes.

Objectives of Maintenance Testing

The objectives of Maintenance Testing are:

• Verify - It verifies the application's functionality after the code changes and makes sure that the new code changes do not affect the existing functionality of the application in the production environment.
• Identify - It identifies the defects in the application after the code changes or in the production environment.
• Prevent Defects - It prevents the defects in the application after the code changes by executing the test cases and verifying the results to ensure that the existing application's functionality is not affected by the code changes.

Example of Maintenance Testing

An example of Maintenance Testing is to verify the e-commerce application functionality after the code changes that are made after the application is in the production environment. The testing team needs to follow below steps:

• Step 1 - Execute the test cases to verify the application's functionality after the code changes.
• Step 2 - Verify the results to ensure that the new code changes do not affect the existing functionality of the application in the production environment.
• Step 3 - If the application's functionality is affected by the code changes, then the testing team needs to report the defects to the development team to fix the defects.
• Step 4 - Once the defects are fixed by the development team, the testing team needs to re-execute the test cases to verify the application's functionality after the code changes.
• Step 5 - Verify the results to ensure that the new code changes do not affect the existing functionality of the application in the production environment.

Types of maintenance Testing

In maintenance testing, we perform all three functional, non-functional, and regression testing again.

Tools for maintenance Testing

The tools for maintenance testing are similar to the tools for functional testing and non-functional testing.

Challenges in maintenance Testing

The challenges in maintenance testing are similar to the challenges in functional testing, non-functional testing and regression testing.

Advantages of maintenance Testing

There are some advantages of Maintenance Testing. They are:

• Quality - It ensures the application's quality after the code changes.
• Requirements Verification - It verifies the application's requirements after the code changes.
• User-Friendly - It ensures that the application is user-friendly after the code changes.
• Defect Detection - It detects the defects in the application after the code changes.

Disadvantages of maintenance Testing

There are some disadvantages of Maintenance Testing. They are:

• Time-Consuming - It is time-consuming to execute the test cases and verify the results after the code changes.
• Complex - It is complex to execute the test cases and verify the results after the code changes.
• Costly - It is costly to execute the test cases and verify the results after the code changes.
• Resource-Intensive - It requires more resources to execute the test cases and verify the results after the code changes.
• Defect Tracking - It is difficult to track the defects after the code changes.
