JUnit Usage and Idioms

Assertions CN - 单元测试的必要语句
Test Runners - how tests should be executed
Aggregating tests in Suites - how to combine multiple related tests into a test suite
Test Execution Order - specifying what order to run unit tests
Exception Testing - how to specify expected exceptions in unit tests
Matchers and assertThat - how to use Hamcrest matchers and more descriptive assertions
Ignoring Tests - how to disable test methods or classes
Timeout for Tests - how to specify maximum execution times for tests
Parameterized Tests - writing tests that can be executed multiple times with different parameter values
Assumptions with Assume - similar to assertions, but without making tests fail
Rules - stop extending abstract test classes and start writing test rules
Theories - write tests that are more like scientific experiments using randomly generated data
Test Fixtures - specify set up and clean up methods on a per-method and per-class basis
Categories - group your tests together for easier test filtering
Use with Maven - how to use JUnit with your Maven build
Use with Gradle - how to use JUnit with your Gradle build
Multithreaded code and Concurrency - basic ideas behind testing concurrent code
Java contract test helpers
Continuous Testing

Custom Runners
net.trajano.commons:commons-testing for UtilityClassTestUtil per #646
System Rules – A collection of JUnit rules for testing code that uses java.lang.System.
JUnit Toolbox – Provides runners for parallel testing, a PoolingWait class to ease asynchronous testing, and a WildcardPatternSuite which allow you to specify wildcard patterns instead of explicitly listing all classes when you create a suite class.
junit-dataprovider – A TestNG like dataprovider (see here) runner for JUnit.
junit-quickcheck – QuickCheck-style parameter suppliers for JUnit theories. Uses junit.contrib's version of the theories machinery, which respects generics on theory parameters.
JGiven - Behavior-Driven Development (BDD) for JUnit
