Detailed Description

UnitTest is a base class for classes that define unit tests.

Each subclass of UnitTest should define one or more test methods. Each test method must be a zero parameter function that returns void. Test methods may be given arbitrary names. Individual test methods should use the preprocessor macro TEST_ASSERT(expression) defined in TextException.h to assert the truth of logical expressions.

The test methods defined by a UnitTest are run by an associated subclass of TestRunner. Each test method of a UnitTest must be added to the associated TestRunner. The run() method of a TestRunner calls all of the associated test methods in the order in which they were added, and counts the number of successful and failed tests.

The TestRunner associated with a single UnitTest is defined by a class template UnitTestRunner, which takes a UnitTest subclass as a template argument. For example, the TestRunner associated with a UnitTest subclass named TestA is a template instantiation UnitTestRunner<TestA>.

Preprocessor macros defined in the file UnitTestRunner.h should be used to create the boiler-plate code necessary to define a unit test runner and to add test methods to it.

Constructor.

Definition at line 219 of file UnitTest.h.

~UnitTest()

UnitTest::~UnitTest ( )

virtual

Destructor.

Definition at line 236 of file UnitTest.h.

Member Function Documentation

setUp()

void UnitTest::setUp ( )

virtual

Set up before each test method (empty default implementation).

Definition at line 242 of file UnitTest.h.

tearDown()

void UnitTest::tearDown ( )

virtual

Tear down after each test method (empty default implementation).

Reimplemented in ParamFileTest.

Definition at line 248 of file UnitTest.h.

setVerbose()

void UnitTest::setVerbose

(

int

verbose

)

Set verbosity level.

Parameters

verbose

verbosity level (0 = silent).

Definition at line 256 of file UnitTest.h.

References verbose().

setFilePrefix()

void UnitTest::setFilePrefix

(

const std::string &

prefix

)

Set file prefix.

This function is called by the UnitTestRunner::method(int i) function to set the filePrefix of the unit test equal to that of the runner after construction but before running the relevant test method.

Parameters

prefix

string to be prepended to input and output file names.

Definition at line 262 of file UnitTest.h.

filePrefix()

const std::string & UnitTest::filePrefix

(

)

Get file prefix string.

Definition at line 268 of file UnitTest.h.

isIoProcessor()

bool UnitTest::isIoProcessor

(

)

const

Should this processor read and write to file?

Definition at line 274 of file UnitTest.h.

printMethod()

void UnitTest::printMethod ( const char *  methodName )

protected

Write name of a class method, iff ioProcessor.

Parameters

methodName

name of class test method

Definition at line 314 of file UnitTest.h.

References isIoProcessor().

printEndl()

void UnitTest::printEndl ( )

protected

Write carriage return, iff isIoProcessor.

Definition at line 324 of file UnitTest.h.

endMarker()

void UnitTest::endMarker ( )

protectedvirtual

Print a line of hashes, iff isIoProcessor.

Definition at line 330 of file UnitTest.h.

References isIoProcessor().

openInputFile()

void UnitTest::openInputFile ( const std::string &  name, std::ifstream &  in  ) const

protected

Open C++ input file ifstream.

This function adds the filePrefix before the name parameter. It does not check if this node isIoProcessor.

Parameters

name	base file name (added to filePrefix).
in	input file (opened on return).

Definition at line 343 of file UnitTest.h.

Referenced by ParamFileTest::openFile().

openOutputFile()

void UnitTest::openOutputFile ( const std::string &  name, std::ofstream &  out  ) const

protected

Open C++ output file ofstream.

This function adds the filePrefix before the name parameter. It does not check if this node isIoProcessor.

Parameters

name	base file name (added to filePrefix)
out	output file (opened on return)

Definition at line 361 of file UnitTest.h.

openFile()

FILE * UnitTest::openFile ( const std::string &  name, const char *  mode  ) const

protected

Open C file handle with specified mode.

This function adds the filePrefix before the name parameter. It does not check if this node isIoProcessor.

Parameters

name	base file name (added to filePrefix)
mode	string that specified read or write mode

Returns

C file handle, opened for reading or writing

Definition at line 379 of file UnitTest.h.

verbose()

int UnitTest::verbose ( ) const

inlineprotected

Return integer verbosity level (0 == silent).

eq() [1/2]

bool UnitTest::eq ( int  s1, int  s2  )

inlinestaticprotected

Return true if two integers are equal.

Definition at line 403 of file UnitTest.h.

eq() [2/2]

bool UnitTest::eq ( double  s1, double  s2  )

staticprotected

Return true if two double precision floats are equal.
