java.lang.Objectorg.junit.runner.Request
public abstract class Request
A Request is an abstract description of tests to be run. Older versions of
JUnit did not need such a concept--tests to be run were described either by classes containing
tests or a tree of Tests. However, we want to support filtering and sorting,
so we need a more abstract specification than the tests themselves and a richer
specification than just the classes.
The flow when JUnit runs tests is that a Request specifies some tests to be run ->
a Runner is created for each class implied by the Request ->
the Runner returns a detailed Description
which is a tree structure of the tests to be run.

filterWith(Description desiredDescription)
Returns a Request that only runs contains tests whose Description
equals desiredDescription |
Request |
filterWith(Filter filter)
Returns a Request that only contains those tests that should run when filter is applied |
abstract Runner |
getRunner()
Returns a Runner for this Request |
static Request |
method(java.lang.Class<?> clazz,
java.lang.String methodName)
Create a Request that, when processed, will run a single test. |
Request |
sortWith(java.util.Comparator<Description> comparator)
Returns a Request whose Tests can be run in a certain order, defined by comparator
For example, here is code to run a test suite in alphabetical order: |
| Methods inherited from class java.lang.Object |
|---|
clone, equals, finalize, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait |

public static Request method(java.lang.Class<?> clazz,
java.lang.String methodName)
Request that, when processed, will run a single test.
This is done by filtering out all other tests. This method is used to support rerunning
single tests.
clazz - the class of the testmethodName - the name of the test
Request that will cause a single test be runpublic static Request aClass(java.lang.Class<?> clazz)
Request that, when processed, will run all the tests
in a class. The odd name is necessary because class is a reserved word.
clazz - the class containing the tests
Request that will cause all tests in the class to be run
public static Request classes(java.lang.String collectionName,
java.lang.Class<?>... classes)
Request that, when processed, will run all the tests
in a set of classes.
collectionName - a name to identify this suite of testsclasses - the classes containing the tests
Request that will cause all tests in the classes to be run
public static Request errorReport(java.lang.Class<?> klass,
java.lang.Throwable cause)
public abstract Runner getRunner()
Runner for this Request
Runner for this Requestpublic Request filterWith(Filter filter)
filter is applied
filter - The Filter to apply to this Request
public Request filterWith(Description desiredDescription)
Description
equals desiredDescription
desiredDescription - Description of those tests that should be run
public Request sortWith(java.util.Comparator<Description> comparator)
comparator
For example, here is code to run a test suite in alphabetical order:
private static Comparator forward() {
return new Comparator() {
public int compare(Description o1, Description o2) {
return o1.getDisplayName().compareTo(o2.getDisplayName());
}
};
}
public static main() {
new JUnitCore().run(Request.aClass(AllTests.class).sortWith(forward()));
}
comparator - definition of the order of the tests in this Request
