Field Detail

LineBreakPattern

private static final Pattern LineBreakPattern

TabPattern

private static final Pattern TabPattern

NL

public static final String NL

System-dependent newline character.

Do not use '\n' in strings which are samples for test results. PrintWriter.println() produces '\n' on Unix and '\r\n' on Windows, but '\n' is always '\n', so your tests will fail on Windows.

lineBreak

private static final String lineBreak

lineBreak2

private static final String lineBreak2

lineBreak3

private static final String lineBreak3

Method Detail

assertEqualsVerbose

public static void assertEqualsVerbose(String expected,
                                       String actual)

quoteForJava

public static String quoteForJava(String s)

Converts a string (which may contain quotes and newlines) into a java literal.

For example,

string with "quotes" split
 across lines

becomes

"string with \"quotes\" split" + NL +
  "across lines"

toJavaString

public static String toJavaString(String s)

Converts a string (which may contain quotes and newlines) into a java literal.

For example,

string with "quotes" split
 across lines

becomes

TestUtil.fold(
  "string with \"quotes\" split\n",
  + "across lines")

fold

public static String fold(String[] strings)

Combines an array of strings, each representing a line, into a single string containing line separators.

fold

public static String fold(String string)

Converts a string containing newlines (\n) into a string containing os-dependent line endings.

quotePattern

public static String quotePattern(String s)

Quotes a pattern.
