Recently, I have studied and implemented the JUnit framework. As a result i am aware of few annotations which are used in JUnit :- @Test
, @Before
,
This Github search (@interface
) gives you the list of all the annotations :
https://github.com/junit-team/junit/search?q=%22%40interface%22&type=Code
@Test @Before @After @AfterClass @BeforeClass @Ignore @Runwith
For Parameterized tests use @Parameters
and @RunWith(Parameterized.class)
https://github.com/junit-team/junit/wiki/Parameterized-tests
@Category
Grouping tests into categories. e.g. Fast, Slow etc.
https://github.com/junit-team/junit/wiki/Categories
@IncludeCategory
Runs only the classes and methods that are
annotated with either the category given with the @IncludeCategory
annotation, or a subtype of that category.
@ExcludeCategory
Inverse of @IncludeCategory
@Rule
Rules allow very flexible addition or redefinition of the behavior of each test method in a test class. e.g. Creating a Temp Folder rule for creating a temp folder while running tests.

@Theory
Theories give more flexible and expressive assertions
https://github.com/junit-team/junit/wiki/Theories
@DataPoint
Annotating an field or method with @DataPoint
will cause the field value
or the value returned by the method to be used as a potential parameter for
theories in that class
@DataPoints
Extension of @Datapoint
Annotating an array or iterable-typed field or method with @DataPoints
will cause the values in the array or iterable given to be used as potential
parameters for theories in that class
@FromDataPoints
Annotating a parameter of a @Theory
method with @FromDataPoints
will limit the
datapoints considered as potential values for that parameter to just the
@DataPoints
with the given name
@ParametersSuppliedBy
Annotating a @Theory
method parameter with @ParametersSuppliedBy
causes it to be supplied with
values from the named ParameterSupplier
when run as a theory
@TestedOn
The @TestedOn
annotation takes an array of values to be used as data points for the annotated
parameter.
e.g.
@Theory
public void multiplyIsInverseOfDivideWithInlineDataPoints(
@TestedOn(ints = {0, 5, 10}) int amount,
@TestedOn(ints = {0, 1, 2}) int m
) {
assumeThat(m, not(0));
assertThat(new Dollar(amount).times(m).divideBy(m).getAmount(), is(amount));
}
