Printing the test results in a compiler compatible format (assertion location has the same format as compiler error), allow you to use your IDE to jump to the assertion failure. Location format can be customized (see setLocationFormat() ).

For example, when running the test in a post-build with VC++, if an assertion fails, you can jump to the assertion by pressing F4 (jump to next error).

Heres is an example of usage (from examples/cppunittest/CppUnitTestMain.cpp):

 int main( int argc, char* argv[] ) {
 // if command line contains "-selftest" then this is the post build check
 // => the output must be in the compiler error format.
 bool selfTest = (argc > 1) && 
 (std::string("-selftest") == argv[1]);
 CppUnit::TextUi::TestRunner runner;
 runner.addTest( CppUnitTest::suite() ); // Add the top suite to the test runner
 
 if ( selfTest )
 { // Change the default outputter to a compiler error format outputter
 // The test runner owns the new outputter.
 runner.setOutputter( new CppUnit::CompilerOutputter( &runner.result(),
 std::cerr ) );
 }
 
 // Run the test and don't wait a key if post build check.
 bool wasSuccessful = runner.run( "", !selfTest );
 
 // Return error code 1 if the one of test failed.
 return wasSuccessful ? 0 : 1;
 }

Constructor & Destructor Documentation

CPPUNIT_NS_BEGIN CompilerOutputter::CompilerOutputter ( TestResultCollector * result,

OStream & stream,

const std::string & locationFormat = CPPUNIT_COMPILER_LOCATION_FORMAT

)

Constructs a CompilerOutputter object.

Parameters:: result Result of the test run.

stream Stream used to output test result.

locationFormat Error location format used by your compiler. Default to CPPUNIT_COMPILER_LOCATION_FORMAT which is defined in the configuration file. See setLocationFormat() for detail.

See also:: setLocationFormat().

CompilerOutputter::~CompilerOutputter ( ) [virtual]

Destructor.

CompilerOutputter::CompilerOutputter ( const CompilerOutputter & copy ) [private]

Prevents the use of the copy constructor.

Member Function Documentation

CompilerOutputter * CompilerOutputter::defaultOutputter ( TestResultCollector * result,

OStream & stream

) [static]

Creates an instance of an outputter that matches your current compiler.

Deprecated:: This class is specialized through parameterization instead of subclassing... Use CompilerOutputter::CompilerOutputter instead.

std::string CompilerOutputter::extractBaseName ( const std::string & fileName ) const [private, virtual]

void CompilerOutputter::operator= ( const CompilerOutputter & copy ) [private]

Prevents the use of the copy operator.

void CompilerOutputter::setLocationFormat ( const std::string & locationFormat )

Sets the error location format.

Indicates the format used to report location of failed assertion. This format should match the one used by your compiler.

The location format is a string in which the occurence of the following character sequence are replaced:

"%l" => replaced by the line number
"%p" => replaced by the full path name of the file ("G:\prg\vc\cppunit\MyTest.cpp")
"%f" => replaced by the base name of the file ("MyTest.cpp")

Some examples:

VC++ error location format: "%p(%l):" => produce "G:\prg\MyTest.cpp(43):"
GCC error location format: "%f:%l:" => produce "MyTest.cpp(43):"

Thoses are the two compilers currently supported (gcc format is used if VC++ is not detected). If you want your compiler to be automatically supported by CppUnit, send a mail to the mailing list (preferred), or submit a feature request that indicates how to detect your compiler with the preprocessor (#ifdef...) and your compiler location format.

void CompilerOutputter::setNoWrap ( )

void CompilerOutputter::setWrapColumn ( int wrapColumn )

int CompilerOutputter::wrapColumn ( ) const

void CompilerOutputter::write ( ) [virtual]

Implements Outputter.
