public class TestQueryEngine_Slice
extends TestCase2

Stress test for SliceOp in which a large number of small chunks are fed into the query such that the concurrency constraints of the slice are stress tested. PipelineOp.isSharedState() returns true so each invocation of the same SliceOp operator instance should use the same SliceOp.SliceStats object. This test will fail if that is not true.

Method Detail

getProperties

public Properties getProperties()

Description copied from class: TestCase2

Reads in the configuration properties for the test from a variety of resources and returns a properties hierarchy. If a property name is not bound at the top-level of the returned Properties object, then the lower levels of the hierarchy are recursively searched.

The hierarchy is constructed from the following properties files in the following order. The first property file in this list corresponds to the top of the property hierarchy. The last property file in this list corresponds to the bottom of the property hierarchy. The property resources are:

1. The System properties specified using the -D argument on the command line.
2. ${user.home}/build.properties. ${user.home} is the value of the Java system environment variable named "user.home" and corresponds to the user home directory. A warning is logged if this properties file does not exist. Note: The JUnit UI can wind up with a different value for this property than when you execute tests without the UI. It is an error if the properties file exists but can not be read.
3. {class}.properties, where {class} is the class name reported by Java reflection, is loaded iff it is found.
4. {class} is repeatedly truncated by dropping the last package name component to generate a package name. If a properties file named "test.properties" exists in that package then those properties are loaded.

Overrides:

getProperties in class TestCase2

Returns:

A Properties object that supplies bindings for property names according to the described hierarchy among property resources. The returned Properties is NOT cached. TODO This does not handle the recursive truncation of the class name to search for "test.properties" yet.
