What is test coverage and its advantages and disadvantages?
Test coverage or Code coverage is a very useful tool which is used to test untested parts of code. Test coverage is a measure which is used to describe the degree to which a source code of program is tested by a particular test suit.
A program with more test coverage has lower chances of containing bugs and a program with lower test coverage has higher chances of containing more bugs.
Benefits of test coverage:-
1) It creates additional test cases to increase test cases
2) It helps in finding areas of a program which are not tested by set of test cases
3) It helps in determining quantitative measure of code coverage, which indirectly measure the quality of a product
Disadvantages of test coverage:-
1)Code coverage measures coverage of what has been written i.e. the code itself; it cannot say anything about the software that has not been written.
