The Groovy LineColumnCheckTestSuite.java source code

package org.codehaus.groovy.ast;

import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
import java.io.Reader;

import junit.framework.TestSuite;

/**
 * Tests the LineColumn information in file specified in TEST_FILE_PATH
 * 
 * The file in the specified path should look like:
 * 
 * ###<testname>:::
 * <source code from which the AST will be built>
 * :::<expected AST output>
 * 
 * The section above can be repeated for every new TestCase
 * 
 * The AST output from the visitor is quite big. Also for small source code snippets. Therefore
 * it is possible to only specify the nodes that you wan't to check and separate them with a semicolon.
 * A semicolon is also needed when you begin with a new line.
