Testing Software Modifications
Question
Martha works as a Project Leader for BlueWell Inc.
She and her team have developed accounting software.
The software was performing well.
Recently, the software has been modified.
The users of this software are now complaining about the software not working properly.
Which of the following actions will she take to test the software?

A. B. C. D.ensure that no existing errors reappear, and no new errors are introduced.
Answer: D is incorrect.
The acceptance testing is performed on the application before.
Regression testing can be performed any time when a program needs to be modified either to add a feature or to fix an error.
It is a process of repeating Unit testing and Integration testing whenever existing tests need to be performed again along with the new tests.
Regression testing is performed to its implementation into the production environment.
It is done either by a client or an application specialist to ensure that the software meets the requirement for more units are combined into a component.
During integration testing, a developer combines two units that have already been tested into a component, and tests the interface between the two units.
Although integration testing can be performed in various ways, the following three approaches are generally used: The top- application is tested separately.
During unit testing, a developer takes the smallest unit of an application, isolates it from the rest of the application code, and tests it to determine whether it works as expected.
Unit testing is performed before integrating these independent units into modules.
The most common approach to unit testing requires drivers and stubs to be written.
Drivers and stubs are programs.
A driver simulates a calling unit, and a stub simulates a called unit.
When users complain about software not working properly, it's a sign that the software has undergone some changes or modifications that have caused it to malfunction. As a Project Leader, Martha needs to investigate the issue and identify the cause of the problem to ensure that the software is working as expected.
To identify the issue, Martha needs to perform testing on the software. Testing is an essential part of the software development lifecycle, and it helps to identify and eliminate defects and errors that can affect the performance of the software. There are different types of testing methods that can be used to identify and eliminate issues in software.
Given the scenario, the best testing approach for Martha to use is regression testing. Regression testing is a type of testing that involves retesting the software after it has been modified or changed to ensure that the modifications did not introduce new issues or defects in the software. Since the software was recently modified and users are complaining about it, regression testing is the best approach to identify and address the issue.
Performing integration testing involves testing how different components of the software interact with each other. It is typically done during the integration phase of the software development lifecycle.
Unit testing involves testing individual units or components of the software to ensure that they are working as expected.
Acceptance testing involves testing the software to ensure that it meets the requirements and expectations of the end-users.
Therefore, in this case, performing regression testing is the best action for Martha to take to test the software and identify the cause of the issue.
