Bottom up testing drivers

 · It is important to write a control program for testing. These control programs are also known as drivers or high-level modules. It simply coordinates input and output of a test case. Testing is done of entire build or cluster containing low-level modules. At lastly, control program or drivers or high levels modules are removed and clusters are integrated by moving Estimated Reading Time: 2 mins. If an error occurs we know that the problem is in one of the modules. + Test 1 such that it calls 3 and If an error occurs we know that the problem is in 3 or in the interface between 1 and 3. Though Top level components are the most important, yet tested last using this strategy. In Bottom-up approach, the Components 2 and 3 are replaced by drivers while testing .  · Drivers: 1. Used in Top-Down Integration Testing. www.doorway.ru in Bottom-Up Integration Testing. 2. A piece of code that emulates the called function. 2. A piece of code that emulates a calling function. 3. Stubs stimulates the activity of missing and not developed modules. 3. Drivers pass test cases to another code and invoke modules under testing. 4.

📢Brief: When ever we talk about software testing, Software Testing strategies in the field of software engineering we often discuss the stubs and drivers, S. Without the dummy program or driver, the complete testing of the module is not possible. Drivers are basically called in BOTTOM UP testing approach. In a bottom-up testing approach the bottom level modules are prepared but the top level modules are not prepared. Testing of the bottom level modules is not possible with the help of the main program. If an error occurs we know that the problem is in one of the modules. + Test 1 such that it calls 3 and If an error occurs we know that the problem is in 3 or in the interface between 1 and 3. Though Top level components are the most important, yet tested last using this strategy. In Bottom-up approach, the Components 2 and 3 are replaced by drivers while testing components 4,5,6,7.
