Code coverage

Code coverage is like playing hide and seek. The code is like the thing that hides and you are like the one who seeks. When you want to know how much of the code you have found, you use code coverage. It tells you how many parts of the code you have found and how much you still need to find. It's like counting the number of things you have found while playing hide and seek so that you know how close you are to finding everything. In simple words, code coverage tells you how much of the code you have tested and how much you have left to test.
