Class BatcherTransform

java.lang.Object
  com.atlassian.jira.functest.framework.suite.BatcherTransform

All Implemented Interfaces:

SuiteTransform, com.google.common.base.Function<Iterable<org.junit.runner.Description>,Iterable<org.junit.runner.Description>>

Direct Known Subclasses:

SystemPropertyBasedBatcherTransform

public abstract class BatcherTransform
extends Object
implements SuiteTransform

A SuiteTransform for batching tests.

NOTE: this class is stateful, as it has to drill down the description tree to find single test cases to batch. Use single instance of this class (or any subclass) per transforming runner. It also needs to know about any preceding transforms that modify the list of descriptions to work correctly.

Since:

v4.4
