Question
A new application will require multiple interfaces.
Which of the following testing methods can be used to detect interface errors early in the development life cycle?
Answers
Explanations
Click on the arrows to vote for the correct answer
A. B. C. D.D.
Of the options given, the testing method that can be used to detect interface errors early in the development life cycle is the "Top Down" testing method (Option B).
The Top Down testing method is a software testing technique that begins with the high-level modules and moves down to lower-level modules. It is a method of integration testing where the topmost module is tested first, followed by the testing of lower-level modules. The objective of this method is to identify interface errors early in the development life cycle.
In the context of an application that requires multiple interfaces, the Top Down testing method is particularly useful because it allows testers to test the application's user interface and ensure that it interacts correctly with the various interfaces. The method works by simulating the behavior of the lower-level modules using stubs or drivers, which are pieces of code that mimic the interface of the modules that have not yet been developed. This allows testing of the interfaces and functionality of the application without waiting for the entire system to be developed.
Acceptance testing (Option A) is typically performed by end-users to ensure that the application meets their requirements and works as intended. It is usually performed towards the end of the development life cycle and is not suitable for detecting interface errors early on.
Sociability testing (Option C) is not a recognized testing method and is not relevant in this context.
Bottom-up testing (Option D) is a testing technique that starts with the lower-level modules and moves up to higher-level modules. It is not an ideal testing method for detecting interface errors in an application with multiple interfaces since it tests the lower-level modules first and does not focus on the interfaces until later in the development life cycle.
In conclusion, the most suitable testing method for detecting interface errors early in the development life cycle for an application with multiple interfaces is the Top Down testing method.
