Stubs
Driver
1
A piece of code that simulates the activity of missing component
A piece of code that passes test case to another piece of code
2
Stubs are created integration testing like Top-down approach
Drivers are created integration testing like bottom-up approach
3
Stubs are simulations of the sub-code that otherwise is very gives full control to the test code
Driver takes care that the entry point of the application is masked by that of the test code and difficult to execute in the test code
4
A stub is a brief section of compilable code that serves as a class
a driver is a brief test program that demonstrates the functionality of a class or a portion of placeholder for future work
5
It is a temporary called program.It functions similarly like sub modules
It is a temporary Calling program.It functions similarly like main module for calling the sub when called by the main module
6
Stub is a simple routine that takes the place of the real routine Stubs let you check the interfaces and higher levels of the program
The approach is to write a program that passes input data to the unit under test and compares the output to the truth
7
A piece of code that simulates the activity of missing components
A piece of code that passes test cases to another piece of code
8
stub is a piece of special code that which is used to simulate the set up environment missing or not yet constructed
driver is a code that which invokes the code to be tested
9
Stub is a skeleton of function having function header. This function can have actual statements or simple statements which can be replaced
with the actual code
Driver is a small program used to test a function
