Description

Interface Summary

TupleFilter

Applies filter functions to sets of entries.

Class Summary

ANDTupleFilter	Applies the AND filter function to two input tuples.
DeletionTest	Regression test to check that files are deleted from the index.
DVPostingsTester	Class DVPostingsTester compares the DocumentVectorPostings in the index with the frequencies of terms in the main dictionary. This only seems to work for lowercase terms.
IndexInverter	Class IndexInverter recreates the list of documents from the index.
MPIndexTest	Multi-threaded index and test.
ORTupleFilter	Applies the OR filter function to two input tuples.
PostTest	A test program that will exercise the postings iterators for a set of partitions.
TestUtils	Utility methods for the regression test package.
Tuple	A tuple consists of a set of documents that are related to each other because of certain conditions regarding the entrys they have.
TupleFactory	Creates tuple objects with documents that contain a certain entry.
TupleRelation	A tuple relation describes the relation of the tuple in entrys of a graph.

Package com.sun.labs.minion.test.regression Description

Provides the classes that generates the entries and queries for the regression test.

The TestEntrySelector selects entries from the index to be used in queries. The TestFieldEntrySelector selects field entries from the index to be used in queries related to fields.

The QueryFactory takes the entries selected from by the TestEntrySelector and TestFieldEntrySelector to create queries for the regression test.

Currently, the regression test targets are in the build.xml file. This test is based on the javadocs for JDK 1.4.2. To run the test, you must first build the index from the javadocs by typing:

ant index_javadocs

in this directory. Then to create the queries, type:

ant create_queries

in this directory. The created queries will be saved in a text file called queries.txt in this directory. Please refer to the documentation in the QueryFactory class for the types of queries that are being generated.

To run the generated queries against the search engine, type:

ant run_queries

All the classes relating to Tuples are not being used at this point. They were intended to figure out how many documents a certain query will return. If we know that, we can tailor our query choices for the regression test to include queries that will return a small, medium, and large number of documents. However, since it will take a long time to compute the number of documents returned for all possible queries, the Tuples stuff is not used at this moment.
