Class MetaTester

java.lang.Object
  org.eigenbase.xom.MetaTester

public class MetaTester
extends Object

The MetaTester class is a utility class for testing generated models. The tester reads a model file in XML, validates it against its DTD, converts it to its corresponding model definition class (always a subclass of ElementDef), and displays the results. The MetaTester may be used to test a model against a suite of input files to verify the model's correctness.

Constructor Summary

MetaTester(String modelFile, String fileDirectory, int parserType)
Constructs a new MetaTester using the given model file, the given test file, and the directory containing all support files.

Method Summary

static void	main(String[] args) The MetaTester tests a suite of test model files against a compiled model.
void	testFile(String testFile, String fileDirectory) Tests a specific instance of the given model, as described by testFile.

Constructor Detail

MetaTester

public MetaTester(String modelFile,
                  String fileDirectory,
                  int parserType)
           throws XOMException,
                  IOException

Constructs a new MetaTester using the given model file, the given test file, and the directory containing all support files.

Throws:

XOMException - if the model file is corrupted or if any of its compiled components cannot be loaded.

IOException

Parameters:

modelFile - an XML file describing the model to be tested. This model should have already been compiled using the MetaGenerator utility.

fileDirectory - the directory containing all output files (Java classes, dtds, etc) from the model compilation. The model and its associated java class must be compiled.

Method Detail

testFile

public void testFile(String testFile,
                     String fileDirectory)
              throws XOMException

Tests a specific instance of the given model, as described by testFile. Testing includes parsing testFile, validating against its associated dtd, and converting to its assocated java class. The contents of the java class are displayed to complete the test.

Throws:

XOMException - if the test fails for any reason.

Parameters:

testFile - the XML file to be tested.

fileDirectory - directory containing files.

main

public static void main(String[] args)
                 throws XOMException,
                        IOException

The MetaTester tests a suite of test model files against a compiled model.

Arguments:

1. The name of the model description file. This is an XML file describing the model itself.
2. The name of the output directory. This output directory should contain all files generated when compiling the model.

All other arguments are the names of the test model files. Each of these will be tested and displayed in turn.

Throws:

XOMException

IOException
