Question

Which of the following best defines a test driver?
A. It is a skeletal or special purpose implementation of a software module, used to develop or test a component that calls it.
B. It is a software component that replaces a component that takes care of the control and/or the calling of a software component.

Answer 1

Answer:

0develop or test a component that calls it.

B. It is a software component that replaces a component that takes

Answer 2

Answer:

The Correct answer is option B

Explanation:

• Bottom-up integration testing uses test drivers to simulate the behavior of the higher-level modules that have not yet been integrated. Test Drivers are the modules that temporarily take the place of a calling module and produce results identical to those of the final product.
• Drivers, which are typically more complex than stubs, are also used when the software needs to communicate with an external system.
• A piece of code that makes it simpler to call other programmed or code modules is known as a driver. The primary programmed that is used to call other modules is known as a driver. It is crucial that we have a main programmed that calls the test module whenever anyone decides to test any module. It is impossible to test a module without a programmed sample.
• Test drivers are employed in software testing's bottom-up integration testing to functionally simulate the behavior of yet-to-be-simulated upper-level modules. These drivers are a group of modules that temporarily take the place of the following calling module and produce the same results.
• When there is a requirement for the interaction with an external system, test drivers are necessary. Test drivers are typically more complex than stubs.

Example:

Let’s consider a student information management application, where we have 4 modules as stated below along with their description:

• Module-A: Login Page
• Module-B: Home Page
• Module-C: Print Setup Page
• Module-D: Logout Page
• These modules all rely on one another in various ways. For instance, you must first validate the login page before you can access the home page (Module-B) (Module-A). Similar to that, you must run or access and validate Home Page in order to test Print Setup Page (Module-C) (Module-B) Additionally, you must first execute the login page (Module A) before you can test the logout page (Module D). Thus, it can be concluded that each module's availability is a necessary requirement for testing the entire application or system, and that it will not be possible to conduct this testing if any of these modules are missing (possibly because they have not yet been created or are not yet available).
