public class ArgumentTokenizerTest
extends DrJavaTestCase

Tests that an ArgumentTokenizer can correctly divide up a string into command line-style arguments. Tries to follow the precedent set by a Unix bash shell in most cases.

Constructor Summary

ArgumentTokenizerTest(String name)
Creates a new ArgumentTokenizer to be used in every test.

Method Summary

protected void	_assertTokenized(String typed, String[] expected) Asserts that the given string is tokenized to become the given array of string arguments.
protected void	_assertTokenized(String typed, String[] expected, boolean stringify) Asserts that the given string is tokenized to become the given array of string arguments.
void	testTokenizeAndStringify() Tests that arguments can be "stringified" properly.
void	testTokenizeArguments() Tests that the argument tokenizer can split up a simple list of arguments.
void	testTokenizeEscapedArgs() Tests that escaped characters just return the character itself.
void	testTokenizeQuotedEscapedArgs() Tests that within a quote, everything is correctly escaped.
void	testTokenizeSingleQuotedArgs() Tests that single quotes can be used as argument delimiters.

ArgumentTokenizerTest

public ArgumentTokenizerTest(String name)

Creates a new ArgumentTokenizer to be used in every test.

Method Detail

_assertTokenized

protected void _assertTokenized(String typed,
                                String[] expected)

Asserts that the given string is tokenized to become the given array of string arguments.

Parameters:

typed - A string containing all arguments (as typed by a user)

expected - What the tokenizer should return

_assertTokenized

protected void _assertTokenized(String typed,
                                String[] expected,
                                boolean stringify)

Asserts that the given string is tokenized to become the given array of string arguments.

Parameters:

typed - A string containing all arguments (as typed by a user)

expected - What the tokenizer should return

stringify - Whether to format the resulting arguments to print out as Strings.

testTokenizeArguments

public void testTokenizeArguments()

Tests that the argument tokenizer can split up a simple list of arguments.

testTokenizeEscapedArgs

public void testTokenizeEscapedArgs()

Tests that escaped characters just return the character itself. Escaped whitespace is considered a character, not a delimiter. (This is how Unix behaves.) not currently enforcing any behavior for a simple implementation using a StreamTokenizer

testTokenizeQuotedEscapedArgs

public void testTokenizeQuotedEscapedArgs()

Tests that within a quote, everything is correctly escaped. (Special characters are passed to the program correctly.)

testTokenizeSingleQuotedArgs

public void testTokenizeSingleQuotedArgs()

Tests that single quotes can be used as argument delimiters. This is consistent with Unix, not with DOS.

testTokenizeAndStringify

public void testTokenizeAndStringify()

Tests that arguments can be "stringified" properly. (ie. formatted to be printed as a String)
