static void CPPUNIT_API fail (const Message &message, const SourceLine &sourceLine=SourceLine())
 Throws a Exception with the specified message and location.
static void CPPUNIT_API fail (std::string message, const SourceLine &sourceLine=SourceLine())
 Throws a Exception with the specified message and location.
static void CPPUNIT_API failIf (bool shouldFail, const Message &message, const SourceLine &sourceLine=SourceLine())
 Throws a Exception with the specified message and location.
static void CPPUNIT_API failIf (bool shouldFail, std::string message, const SourceLine &sourceLine=SourceLine())
 Throws a Exception with the specified message and location.
static std::string CPPUNIT_API makeExpected (const std::string &expectedValue)
 Returns a expected value string for a message. Typically used to create 'not equal' message, or to check that a message contains the expected content when writing unit tests for your custom assertions.
static std::string CPPUNIT_API makeActual (const std::string &actualValue)
 Returns an actual value string for a message. Typically used to create 'not equal' message, or to check that a message contains the expected content when writing unit tests for your custom assertions.

Detailed Description

A set of functions to help writing assertion macros.

Here is an example of assertion, a simplified version of the actual assertion implemented in examples/cppunittest/XmlUniformiser.h: 

 #include <cppunit/SourceLine.h>
 #include <cppunit/TestAssert.h>
 
 void 
 checkXmlEqual( std::string expectedXml,
                std::string actualXml,
                CppUnit::SourceLine sourceLine )
 {
   std::string expected = XmlUniformiser( expectedXml ).stripped();
   std::string actual = XmlUniformiser( actualXml ).stripped();
 
   if ( expected == actual )
     return;
 
   ::CppUnit::Asserter::failNotEqual( expected,
                                      actual,
                                      sourceLine );
 }
 
 #define CPPUNITTEST_ASSERT_XML_EQUAL( expected, actual ) \
     checkXmlEqual( expected, actual,                     \
                    CPPUNIT_SOURCELINE() )

CPPUNIT_NS_BEGIN void Asserter::fail (  std::string  message,
const SourceLine &  sourceLine = SourceLine()
)  [static]
 

Throws a Exception with the specified message and location.

Deprecated:
Use fail( Message, SourceLine ) instead.

void Asserter::fail (  const Message &  message,
const SourceLine &  sourceLine = SourceLine()
)  [static]
 

Throws a Exception with the specified message and location.

void Asserter::failIf (  bool  shouldFail,
std::string  message,
const SourceLine &  sourceLine = SourceLine()
)  [static]
 

Throws a Exception with the specified message and location.

Deprecated:
Use failIf( bool, Message, SourceLine ) instead.
Parameters:
shouldFail if true then the exception is thrown. Otherwise nothing happen.
message Message explaining the assertion failiure.
sourceLine Location of the assertion.

void Asserter::failIf (  bool  shouldFail,
const Message &  message,
const SourceLine &  sourceLine = SourceLine()
)  [static]
 

Throws a Exception with the specified message and location.

Parameters:
shouldFail if true then the exception is thrown. Otherwise nothing happen.
message Message explaining the assertion failiure.
sourceLine Location of the assertion.

void Asserter::failNotEqual (  std::string  expected,
std::string  actual,
const SourceLine &  sourceLine,
const AdditionalMessage &  additionalMessage = AdditionalMessage(),
std::string  shortDescription = "equality assertion failed"
)  [static]
 

Throws an Exception with the specified message and location.

Parameters:
expected Text describing the expected value.
actual Text describing the actual value.
sourceLine Location of the assertion.
additionalMessage Additional message. Usually used to report what are the differences between the expected and actual value.
shortDescription Short description for the failure message.

void Asserter::failNotEqualIf (  bool  shouldFail,
std::string  expected,
std::string  actual,
const SourceLine &  sourceLine,
