Field Summary

protected LpLexer

lexer

Constructor Summary

LpLexerTest(String testName)
A default test case constructor.

Method Summary

protected void	doTest(String source, List<LpToken> expectedTokens) Uses lexer to tokenize source and compares the results with contents of expectedTokens.
void	testAfterClose() Tests the default values the lexer should return after LpLexer.close() is called.
void	testComments() Tests the lexer on an input containing some comments.
void	testDefaultValues() Tests the default values the lexer should return before LpLexer.nextToken() is called for the first time.
protected void	testEqual(LpToken expected, LpToken actual) Tests whether actual is as expected.
protected void	testEqual(LpToken expected, LpTokenType type, String lexem, int lineNumber, int position) Tests whether a type, lexem, position and lineNumber are as expected.
void	testSetInputExceptions() Tests the lexer on null input (a IllegalArgumentException should be thrown).
void	testTokens() Tests the lexer on a more complicated input.
void	testTokensSimple() Tests the lexer on an input containing all types of tokens.
void	testWhiteSpace() Tests the lexer on an input with lots of whitespace.

Constructor Detail

LpLexerTest

public LpLexerTest(String testName)

A default test case constructor.

Parameters:

testName - the name of the test case

Method Detail

testWhiteSpace

public void testWhiteSpace()

Tests the lexer on an input with lots of whitespace.

Throws:

IOException - if an I/O error occurs while reading the input (should never happen)

testComments

public void testComments()

Tests the lexer on an input containing some comments.

Throws:

IOException - if an I/O error occurs while reading the input (should never happen)

testTokensSimple

public void testTokensSimple()

Tests the lexer on an input containing all types of tokens.

Throws:

IOException - if an I/O error occurs while reading the input (should never happen)

testTokens

public void testTokens()

Tests the lexer on a more complicated input.

Throws:

IOException - if an I/O error occurs while reading the input (should never happen)

testDefaultValues

public void testDefaultValues()

Tests the default values the lexer should return before LpLexer.nextToken() is called for the first time.

Throws:

IOException - if an I/O error occurs while reading the input (should never happen)

testAfterClose

public void testAfterClose()

Tests the default values the lexer should return after LpLexer.close() is called.

Throws:

IOException - if an I/O error occurs while reading the input (should never happen)

testSetInputExceptions

public void testSetInputExceptions()

Tests the lexer on null input (a IllegalArgumentException should be thrown).

Throws:

IOException - if an I/O error occurs while reading the input (should never happen)

doTest

protected void doTest(String source,
                      List<LpToken> expectedTokens)

Uses lexer to tokenize source and compares the results with contents of expectedTokens.

Throws:

IOException - (wrapped in an ExceptionAdapter) if an I/O error occurs while reading the input (should never happen)

testEqual

protected void testEqual(LpToken expected,
                         LpToken actual)

Tests whether actual is as expected.

Parameters:

expected - the expected value

actual - the tested LpToken.

testEqual

protected void testEqual(LpToken expected,
                         LpTokenType type,
                         String lexem,
                         int lineNumber,
                         int position)

Tests whether a type, lexem, position and lineNumber are as expected.

Parameters:

expected - a LpToken instance containg the correct values

type - the tested LpTokenType

lexem - the tested lexem

lineNumber - the tested line number

position - the tested position
