Member Function Documentation

bool test0::run ( ) [inline, virtual]

[virtual] ==> Executes test and returns "false" if not successful.

[***] It is always mandatory to redefine method run().

See also:: runBare().

Implements TestCase.

Definition at line 6 of file test0.cpp.

void TestCase::runBare ( ) [inline, inherited]

Excecutes the test run setUp(); run(); tearDown();.

In contrast to run(), this method will setup the environment for the test run invoking setUp() and tearDown() before and after the test.

    {{  // test::run()
        class MyTest : public TestCase {
            int m_val;
        public:
            MyTest() : m_val(0) {} // init: m_val == 0;
            void setUp() { m_val = 1; }
            void tearDown() { m_val = 2; }
            bool run() {
                assertTrue( m_val == 1 );
                return wasSuccessful();
            }
        }; // MyTest
        TestSuite<TestCase> SSS;
        SSS.addTest( new MyTest );  SSS.addTest( new MyTest );
        assertTrue( 2 == SSS.countTestCases() );
        assertTrue( "" == SSS.failureString() );

        SSS.runBare(); // Ok ==> setUp() sets [m_val == 1]
        assertTrue( "" == SSS.toXML() );

        SSS.run();  // Failure: [m_val == 2] ==> value set by tearDown()
        std::string sssXML = SSS.toXML();
        assertTrue( "" != sssXML ); // SSS contains failures.
        assertTrue( sssXML.find("m_val") != string::npos );
        assertTrue( SSS.runCount() == 2+2 );
    }}

Reimplemented in TestSuite< TestCase >.

Definition at line 777 of file BUnit.h.

bool TestCase::Run ( ) [inline, inherited]

Synonym for run().

Definition at line 123 of file BUnit.h.

bool TestCase::runTest ( ) [inline, inherited]

Synonym for run().

Definition at line 124 of file BUnit.h.

void TestCase::setUp ( ) [inline, virtual, inherited]

Sets the environment for the test run.

As TestCase::run() is an abstract method, to facilitate programming it is usual for the programmer not to invoke TestCase::setUp() and TestCase::tearDown() because it is easier to have TestSuite<TestCase>::runBare() do it.
In contrast with TestCase::runBare(), method TestCase::run() will not establish the test environment because it does not invoke neither TestCase::setUp() before the test run nor TestCase::tearDown() after the test run.
TestSuite<TestCase>::runBare() invokes methods TestCase::setUp() and TestCase::tearDown() when the test run is executed.
If the client programmer wants each test run to stablish it test environment, it is easier to put all test cases into a test collection TestSuite and execute all of them invoking TestSuite<TestCase>::runBare().

Reimplemented in test_rational< INT >, ADH::test_Graph, and test1.

Definition at line 831 of file BUnit.h.

void TestCase::tearDown ( ) [inline, virtual, inherited]

Destroys the test environment.

Definition at line 839 of file BUnit.h.

int TestCase::countTestCases ( ) const [inline, inherited]

1 == Number of test cases.

The value returned always is one 1 because class TestCase represents a single test case. For the container TestSuite<> the value returned can be bigger than 1.

A "test case" is a class, derived from class TestCase.
A "test run" gets counted when either a specific test succeeds or fails.
A "test run" gets counted when protected method TestCase::testThis() is executed, either directly or through any BUnit "assert()" macro, as assertTrue(), fail_Msg(), assertEquals_Delta(), or others like BUnit_SUCCESS() or BUnit_TEST().
A "test case" ussually has many "test runs". A collection of "test cases" resided within an instance derived from class TestSuite<>.

Reimplemented in TestSuite< TestCase >.

Definition at line 127 of file BUnit.h.

int TestCase::runCount ( ) const [inline, inherited]

Number of test runs.

Synonym for successCount()+failureCount()+errorCount().
See also:
reset().

Definition at line 129 of file BUnit.h.

int TestCase::failureCount ( ) const [inline, virtual, inherited]

Number of test runs that failed.

See also:: reset().

Reimplemented in TestSuite< TestCase >.

Definition at line 130 of file BUnit.h.

int TestCase::errorCount ( ) const [inline, inherited]

Always returns 0 (cero): "Number of errors".

BUnit does not maintain separate counts for "errors" and "failures".

Definition at line 131 of file BUnit.h.

int TestCase::successCount ( ) const [inline, virtual, inherited]

Number of successful test runs.

See also:: reset().

Reimplemented in TestSuite< TestCase >.

Definition at line 132 of file BUnit.h.

bool TestCase::wasSuccessful ( ) const [inline, inherited]

Returns "true" when all test runs where successful.

Synonym for (successCount() == runCount())

Definition at line 134 of file BUnit.h.

void TestCase::reset ( ) [inline, virtual, inherited]

Discards all test runs.

Resets to cero al counters because the test case is left in the state it had when initially contructed.
Deletes the record for not successful tests.

Does not change the test case name.

    {{  // test::reset()

std::string TestCase::getName ( ) const [inline, inherited]

Gets the test case name.

See also:: setName().

Definition at line 731 of file BUnit.h.

void TestCase::setName ( const char * name = 0 ) [inline, inherited]

Sets the test case name to "name".

When "name" is a null string or pointer, later typeid(*this).name() will be invoked to get the test´s name.

Returns string summary() followed by toString().

Definition at line 142 of file BUnit.h.

const std::string TestCase::failureString ( ) const [inline, inherited]

Synonym for toString().

Definition at line 143 of file BUnit.h.

void TestCase::recordSuccess ( ) [inline, protected, inherited]

Records the test run as a success.

Definition at line 146 of file BUnit.h.

void TestCase::recordFailure	(	const char *	label,
		const char *	fname,
		int	lineno,
		bool	must_copy = `false`
	)		`[inline, protected, inherited]`

Records that the test run did not succeed.

Values "fname" and "lineno" indicate the file and line where the test run is executed.
The values form "fname" and "lineno" are usuallly obtained invoking global macros "__FILE__" and "__LINE__".
"must_copy" forces a copy of string label to be created in dynamic memory. This dynamic memory will be destroyed when the test case gets destroyed or when method TestCase::reset() gets invoked.
Oftentimes string "label" is a constant string generated by the preprocessor macro using #cond; this string constant is not stored in dynamic memory and it must not be destroyed.

This method is invoked using macro BUnit_FAILURE().

Definition at line 945 of file BUnit.h.

void TestCase::recordFailure	(	const std::string &	label,
		const char *	fname,
		int	lineno
	)		`[inline, protected, inherited]`

Records that the test did not succeed.

En BUnit.h there is no difference between "failures" and "errors".

Definition at line 1004 of file BUnit.h.

void TestCase::testThis	(	bool	cond,
		const char *	label,
		const char *	fname,
		long	lineno,
		bool	must_copy = `false`
	)		`[inline, protected, inherited]`

Executes the test and records its result.

If the test is successful only increases the numbero of success successCount().
If the test is not successful reports in toString() this fact.
The result of the test is "cond".
Values "fname" and "lineno" show the file and line of the executed test.
Usuallyy "fname" and "lineno" are values obtained with global macros "__FILE__" and "__LINE__".
The value for "must_copy" indicates whether it is necessary to make a copy of string "label"; this copy will be destroyed when the record of not successful test is deleted.

Most of the time string "label" is a constant genertated by the preprocessor when using macro #cond its memory must not be returned. This method is invoked using macro BUnit_TEST().

    {{  // test::testThis()
        class MyTest : public TestCase {
        public:
            bool run() {
                bool dont_copy = false;
                testThis( 2 == 2, "2 is 2", __FILE__, __LINE__, dont_copy ); // Ok
                testThis( 1 == 2, "1 is 2", __FILE__, __LINE__, dont_copy ); // failure #1
                testThis( 2 == 1, "2 is 1", __FILE__, __LINE__, dont_copy ); // failure #2
                return wasSuccessful();
            }
        }; // MyTest
        MyTest thisTest;
        assertTrue( thisTest.wasSuccessful() ); // run() has not been executed
        thisTest.run(); // 2 failures
        assertTrue( thisTest.failureCount() == 2 );
        assertTrue( ! thisTest.wasSuccessful() );
