public class TestQueryEngine_SortOp
extends TestCase2

Test suite ORDER BY operators when integrated with the query engine. This test suite is designed to examine cases where the ORDER BY operator will have to buffer multiple chunks of solutions before finally placing the buffered solutions into a total order.

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.

doOrderByTest

protected void doOrderByTest(int maxInt,
                 long timeout,
                 int ntrials,
                 int poolSize)
                      throws Exception

Test helper for ORDER_BY tests. We can judge correctness by ensuring that (a) all solutions are visited (either by probing to verify that each solution defined and visited or using a counter) and by (b) verifying that the solutions are visited in an order for which the comparator never returns LT ZERO (0) when comparing with the previous solution visited by the query iterator.

Parameters:

maxInt - The maximum value of the variable in the synthetic data.

timeout -

ntrials -

poolSize -

Throws:

Exception
