public abstract class RunnerBuilder extends Object
RunnerBuilders. A custom runner class with a constructor taking
a RunnerBuilder parameter will be passed the instance of RunnerBuilder used to build that runner itself.
For example,
imagine a custom runner that builds suites based on a list of classes in a text file:
\@RunWith(TextFileSuite.class)
\@SuiteSpecFile("mysuite.txt")
class MySuite {}
The implementation of TextFileSuite might include:
public TextFileSuite(Class testClass, RunnerBuilder builder) {
// ...
for (String className : readClassNames())
addRunner(builder.runnerForClass(Class.forName(className)));
// ...
}

In case of an exception a runner will be returned that prints an error instead of running tests.
Note that some of the internal JUnit implementations of RunnerBuilder will return
null from this method, but no RunnerBuilder passed to a Runner constructor will
return null from this method.
