junit.framework.Test

public class GraphParserTest

extends junit.framework.TestCase

A [JUnit] test for GraphParser.

Each parser test case functions by creating a StringReader from a string, a lexer based on the reader and a parser based on the lexer. Then the test case calls the parser's parse method and checks whether there was a syntax error exception - if no exception was expected, the test fails; if an exception was expected and there was none, the test fails; otherwise it succeeds (unless there was an unexpected exception, i.e. a non-syntax-error exception.

Method Summary

void	testErrSyntax(java.lang.String s) A helper method for the invalid syntax tests A syntax error exception is expected.
void	testForgottenSemi() Test for invalid syntax: no semicolon at the end of an adjacency list item.
void	testOkFull() Test for valid syntax, with all optional parts in.
void	testOkNoAttrList() Test for valid syntax, with the optional node and edge attribute part out.
void	testOkNoGraphAttr() Test for valid syntax, with the optional global attribute part out.
void	testOkOnlyTopology() Test for valid syntax, with only the required topology part in.
void	testOkSyntax(java.lang.String s) A helper method for the valid syntax tests.
void	testWithSemi() Test for valid syntax; identical with the testForgottenSemi test case but with the forgotten semicolon back in.
static void	tryParse(java.lang.String s) A helper method to create the parser from a string and trying the parse.

Method Detail

testOkFull

public void testOkFull()

Test for valid syntax, with all optional parts in.

testOkNoGraphAttr

public void testOkNoGraphAttr()

Test for valid syntax, with the optional global attribute part out.

testOkNoAttrList

public void testOkNoAttrList()

Test for valid syntax, with the optional node and edge attribute part out.

testOkOnlyTopology

public void testOkOnlyTopology()

Test for valid syntax, with only the required topology part in.

testForgottenSemi

public void testForgottenSemi()

Test for invalid syntax: no semicolon at the end of an adjacency list item.

testWithSemi

public void testWithSemi()

Test for valid syntax; identical with the testForgottenSemi test case but with the forgotten semicolon back in.

testOkSyntax

public void testOkSyntax(java.lang.String s)

A helper method for the valid syntax tests.

No exceptions are expected.

testErrSyntax

public void testErrSyntax(java.lang.String s)

A helper method for the invalid syntax tests

A syntax error exception is expected. Other exceptions cause a failure.

tryParse

public static void tryParse(java.lang.String s)

A helper method to create the parser from a string and trying the parse.
