Driver and stub

Stubs and Drivers are two different types of dummy codes and hence are used differently. Stubs are used as functions in Top Down Integration, whereas drivers are used as functions in Bottom Up Integration. Stubs and Drivers are commonly used in porting, distributed computing, as well as general software development and testing.  · Drivers and stubs simulate features and functionalities, and have ability to serve features that a module can provide. This reduces useless delay in testing and makes the testing process faster. Stubs are mainly used in Top-Down integration testing while the Drivers are used in Bottom-up integration testing, thus increasing the efficiency of testing www.doorway.ruted Reading Time: 5 mins.  · Stubs and drivers are often viewed as throwaway code. However, they do not have to be thrown away: Stubs can be "filled in" to form the actual method. Drivers can become automated test cases.

Stubs and drivers are two types of test harness, which is a collection of software and test that is configured together in order to test a unit of a program by stimulating variety of conditions while constantly monitoring its outputs and behaviour. Stubs and drivers are used in top-down integration and bottom-up integration testing respectively and are created mainly for the testing purpose. Stubs and Drivers are two different types of dummy codes and hence are used differently. Stubs are used as functions in Top Down Integration, whereas drivers are used as functions in Bottom Up Integration. Stubs and Drivers are commonly used in porting, distributed computing, as well as general software development and testing. A stub is basically a piece of code that simulates the activity of missing modules. I just accept the value from the calling module and returns a null value. Driver. A driver is a piece of code which is emulating a calling function. Basically, we call the driver as the main function which calls other modules to form complete applications. Drivers are created in integration testing following a bottom-up approach.

Short introduction to stub testing and driver testing. Stubs and Drivers are used in integration testing for TOP-DOWN and BOTTOM-UP testing respectively. Test Driver, Test Drivers are used during Bottom-up integration testing in order to interact with an external system and are usually complex than stubs. 1. Drivers. Drivers are tools used to control and operate the software being tested. One of the simplest examples of a driver is a batch file, a simple list.
