public class PlatformTestCase
PlatformTestCase is the base class for JUnit tests that are platform agnostic. That is using the TestPlatform
interface each test can be run against all supported platform like Hadoop or Cascading local mode.
FieldedPipesPlatformTest
or related tests to see how
this class is used.
This test case uses the PlatformRunner
to inject the available platform providers which implement the
TestPlatform base class.
By default the PlatformRunner looks for "cascading/platform/platform.properties" file in the classpath, and
instantiates the class specified by the "platform.classname" property. If more than one "platform.properties"
resource is found, each class is instantiated and the whole suite of tests will be run against each instance.
To limit this, setting the system property "platform.includes" to list the platform names that should be run will
cause the PlatformRunner to ignore any unlisted platforms. Thus setting platform.includes=local
, only
local mode will run even if the "hadoop" platform was found in the classpath.
To pass custom properties to each test to be used by the FlowConnector
, create
system properties prefixed by "platform.". These properties, minus the "platform." prefix in the property name,
will override any defaults.
Subclasses of PlatformTestCase can set "useCluster
to true
on the constructor if the underlying
platform can boot a cluster for testing. By setting the system property "test.cluster.enabled" to false, this
can be deactivated in order to temporarily speed test execution. By default useCluster
is false
,
typically user tests don't need to have a cluster running to test their functionality so leaving the default is
reasonable.
