Unit Tests...
-
verify the functionality of a specific section of code
- written by developers
-
white-box style testing
-
usually at the method level
-
in OOP, usually at the class level
-
automated tests as documentation
Unit Tests...
- find problems early
- easier refactoring
Unit Tests...
- like writing client for your code
- make you to look at the user's (other developer's or just yourself's) perspective
Unit Tests...
"A failure in a high-level test is not just a bug in functional code, it's also a missing unit test"
~Martin Fowler
Unit Tests & TDD
Test-Driven Development lifecycle
How to Practice on Unit Testing & TDD?
- Find test-less modules via SonarQube and write tests for them
- Read test codes written by others
- Pair Programming
- Use TDD Code Katas:
Code Coverage...
is a measure used to describe the degree to which the source code of a program is executed when a particular test suite runs.
Metrics:
- Line coverage
- Method coverage
- Class coverage
Code Coverage...
"I get paid for code that works, not for tests, so my philosophy is to test as little as possible to reach a given level of confidence..."
~Kent Beck
Continuous Integration
In XP, CI was intended to be used in combination with automated unit tests written through the practices of test-driven development.
