Package org.apache.hadoop.hbase

Class HBaseClassTestRule

java.lang.Object

org.apache.hadoop.hbase.HBaseClassTestRule

All Implemented Interfaces:

org.junit.rules.TestRule

@Private
public final class HBaseClassTestRule
extends Object
implements org.junit.rules.TestRule

The class level TestRule for all the tests. Every test class should have a ClassRule with it.

For now it only sets a test method timeout based off the test categories small, medium, large. Based on junit Timeout TestRule; see https://github.com/junit-team/junit/wiki/Rules

Method Details

getClazz

public Class<?> getClazz()

Mainly used for HBaseClassTestRuleChecker to confirm that we use the correct class to generate timeout ClassRule.

getTimeoutInSeconds

private static long getTimeoutInSeconds(Class<?> clazz)

getNumParameters

static int getNumParameters(Class<?> clazz)

Parameters:

clazz - Test class that is running.

Returns:

 Method method)

Helper method that checks if the input method is a valid JUnit @Parameters method.

Parameters:

method - Input method.

Returns:

true if the method is a valid JUnit parameters method, false otherwise.
