QT_BEGIN_NAMESPACE

/*!
   \namespace QTest
   \inmodule QtTest

   \brief The QTest namespace contains all the functions and
   declarations that are related to the QTestLib tool.

   Please refer to the \l{QTestLib Manual} documentation for information on
   how to write unit tests.
*/

/*! \macro QVERIFY(condition)

   \relates QTest

   The QVERIFY() macro checks whether the \a condition is true or not. If it is
   true, execution continues. If not, a failure is recorded in the test log
   and the test won't be executed further.

   \bold {Note:} This macro can only be used in a test function that is invoked
   by the test framework.

   Example:
   \snippet doc/src/snippets/code/src_qtestlib_qtestcase.cpp 0

   \sa QCOMPARE()
*/

/*! \macro QVERIFY2(condition, message)

    \relates QTest

    The QVERIFY2() macro behaves exactly like QVERIFY(), except that it outputs
    a verbose \a message when \a condition is false. The \a message is a plain
    C string.

    Example:
    \snippet doc/src/snippets/code/src_qtestlib_qtestcase.cpp 1

    \sa QVERIFY(), QCOMPARE()
*/

/*! \macro QCOMPARE(actual, expected)

   \relates QTest

   The QCOMPARE macro compares an \a actual value to an \a expected value using
   the equals operator. If \a actual and \a expected are identical, execution
   continues. If not, a failure is recorded in the test log and the test
   won't be executed further.

   In the case of comparing floats and doubles, qFuzzyCompare() is used for
   comparing. This means that comparing to 0 will likely fail. One solution
   to this is to compare to 1, and add 1 to the produced output.

   QCOMPARE tries to output the contents of the values if the comparison fails,
   so it is visible from the test log why the comparison failed.

   QCOMPARE is very strict on the data types. Both \a actual and \a expected
   have to be of the same type, otherwise the test won't compile. This prohibits
   unspecified behavior from being introduced; that is behavior that usually
   occurs when the compiler implicitly casts the argument.

   If you use QCOMPARE() to compare two QStringList objects, it will start
   comparing the objects from the end of the lists.

   For your own classes, you can use \l QTest::toString() to format values for
   outputting into the test log.

   \note This macro can only be used in a test function that is invoked
   by the test framework.

   Example:
   \snippet doc/src/snippets/code/src_qtestlib_qtestcase.cpp 2

   \sa QVERIFY(), QTest::toString()
*/

/*! \macro QFETCH(type, name)

   \relates QTest

   The fetch macro creates a local variable named \a name with the type \a type
   on the stack. \a name has to match the element name from the test's data.
   If no such element exists, the test will assert.

   Assuming a test has the following data:

   \snippet doc/src/snippets/code/src_qtestlib_qtestcase.cpp 3

   The test data has two elements, a QString called \c aString and an integer
   called \c expected. To fetch these values in the actual test:

   \snippet doc/src/snippets/code/src_qtestlib_qtestcase.cpp 4

   \c aString and \c expected are variables on the stack that are initialized with
   the current test data.

   \bold {Note:} This macro can only be used in a test function that is invoked
   by the test framework. The test function must have a _data function.
*/

/*! \macro QWARN(message)

   \relates QTest
   \threadsafe

   Appends \a message as a warning to the test log. This macro can be used anywhere
   in your tests.
*/

/*! \macro QFAIL(message)

   \relates QTest

   This macro can be used to force a test failure. The test stops
   executing and the failure \a message is appended to the test log.

   \bold {Note:} This macro can only be used in a test function that is invoked
   by the test framework.

   Example:

/*! \macro QTEST(actual, testElement)

   \relates QTest

   QTEST() is a convenience macro for \l QCOMPARE() that compares
   the value \a actual with the element \a testElement from the test's data.
   If there is no such element, the test asserts.

   Apart from that, QTEST() behaves exactly as \l QCOMPARE().

   Instead of writing:

   \snippet doc/src/snippets/code/src_qtestlib_qtestcase.cpp 6

   you can write:

   \snippet doc/src/snippets/code/src_qtestlib_qtestcase.cpp 7

/*! \macro QSKIP(description, mode)

   \relates QTest

   The QSKIP() macro stops execution of the test without adding a failure to the
   test log. You can use it to skip tests that wouldn't make sense in the current
   configuration. The text \a description is appended to the test log and should
   contain an explanation why the test couldn't be executed. \a mode is a QTest::SkipMode
   and describes whether to proceed with the rest of the test data or not.

   \bold {Note:} This macro can only be used in a test function that is invoked
   by the test framework.

   Example:
   \snippet doc/src/snippets/code/src_qtestlib_qtestcase.cpp 8

   \sa QTest::SkipMode
*/

/*! \macro QEXPECT_FAIL(dataIndex, comment, mode)

   \relates QTest

   The QEXPECT_FAIL() macro marks the next \l QCOMPARE() or \l QVERIFY() as an
   expected failure. Instead of adding a failure to the test log, an expected
   failure will be reported.

   If a \l QVERIFY() or \l QCOMPARE() is marked as an expected failure,
   but passes instead, an unexpected pass (XPASS) is written to the test log.

   The parameter \a dataIndex describes for which entry in the test data the
   failure is expected. Pass an empty string (\c{""}) if the failure
   is expected for all entries or if no test data exists.

   \a comment will be appended to the test log for the expected failure.

   \a mode is a \l QTest::TestFailMode and sets whether the test should
   continue to execute or not.

   \bold {Note:} This macro can only be used in a test function that is invoked
   by the test framework.

   Example 1:
   \snippet doc/src/snippets/code/src_qtestlib_qtestcase.cpp 9

   In the example above, an expected fail will be written into the test output
   if the variable \c i is not 42. If the variable \c i is 42, an unexpected pass
   is written instead. The QEXPECT_FAIL() has no influence on the second QCOMPARE()
   statement in the example.

   Example 2:
   \snippet doc/src/snippets/code/src_qtestlib_qtestcase.cpp 10

   The above testfunction will not continue executing for the test data
   entry \c{data27}.

    Executes tests declared in \a testObject. In addition, the private slots
    \c{initTestCase()}, \c{cleanupTestCase()}, \c{init()} and \c{cleanup()}
    are executed if they exist. See \l{Creating a Test} for more details.

    Optionally, the command line arguments \a argc and \a argv can be provided.
    For a list of recognized arguments, read \l {QTestLib Command Line Arguments}.

    For stand-alone tests, the convenience macro \l QTEST_MAIN() can
    be used to declare a main method that parses the command line arguments
    and executes the tests.

    Returns 0 if all tests passed. Returns a value other than 0 if tests failed
    or in case of unhandled exceptions. The return value from this function is
    also the exit code of the test application when the \l QTEST_MAIN() macro
    is used.

    The following example will run all tests in \c MyFirstTestObject and
    \c{MySecondTestObject}:

    \snippet doc/src/snippets/code/src_qtestlib_qtestcase.cpp 18

    Note: This function is not reentrant, only one test can run at a time. A
    test that was executed with qExec() can't run another test via qExec() and
    threads are not allowed to call qExec() simultaneously.

    If you have programatically created the arguments, as opposed to getting them
    from the arguments in \c main(), it is likely of interest to use
    QTest::qExec(QObject *, const QStringList &) since it is Unicode safe.
