Code coverage measures how much code of the application is being exercised when the tests are run. Measurement of Coverage can be determined by the following formula. Coverage= Number of coverage items exercised / Total number of coverage items *100%.

- Readable.
- Reliable.
- Fast.
- Truly unit, not integration.
What is unit testing with example?

The way I define "good" unit tests, is if they posses the following three properties: They are readable (naming, asserts, variables, length, complexity..) They are Maintainable (no logic, not over specified, state-based, refactored..) They are trust-worthy (test the right thing, isolated, not integration tests..)Is unit testing possible or even desirable in all circumstances?

You should be able to run unit test a thousand times and it should give the same results always. Unit testing is not intended to test the complete functionality of an application. Database access falls outside the scope of unit testing, so you would not write unit tests that include database access.Is unit testing necessary?

- Continuously Refactor Test Code.
- Build Your Own Set of Utilities.
- Always Write Tests for Bugs.
