Testing in OO

Testing can either break your code or make your code unbreakable. We recently talked about testing driven development, however in Object-Oriented paradigm testing need to take into account more thing than they noramally should.

1.  The case you want to test only applies to a particular class.
2. There are testing methods that check wether or not the methods of the class are working correctly with each other.
3. OO testing need to check if inheritance breaks the code because inheritance is an important part of the paradigm.

Those are a few different aproaches on testing on OO, I will mention a few below.

Code testing: this type of testing is carried out on the coding stage, you review the code, you debugg, etc.

Unit testing: This aproach review the system based on modules, each tester test modules to figure out what is the problem and how to solve it.

System testing: In this test, the tester will try the whole system at once, like a black box, to see what kind of input can break the program
