\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:
\snippet doc/src/snippets/code/src_qtestlib_qtestcase.cpp 5
*/
/*! \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
\sa QCOMPARE()
*/
/*! \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}.
\sa QTest::TestFailMode, QVERIFY(), QCOMPARE()
*/
/*! \macro QTEST_MAIN(TestClass)
\relates QTest
Implements a main() function that instantiates a QApplication object and
the \a TestClass, and executes all tests in the order they were defined.
Use this macro to build stand-alone executables.
Example:
\snippet doc/src/snippets/code/src_qtestlib_qtestcase.cpp 11
\sa QTEST_APPLESS_MAIN(), QTest::qExec()
*/
/*! \macro QTEST_APPLESS_MAIN(TestClass)
\relates QTest
Implements a main() function that executes all tests in \a TestClass.
Behaves like \l QTEST_MAIN(), but doesn't instantiate a QApplication
object. Use this macro for really simple stand-alone non-GUI tests.
\sa QTEST_MAIN()
*/
/*! \macro QTEST_NOOP_MAIN()
\relates QTest
Implements a main() function with a test class that does absolutely nothing.
Use this macro to create a test that produces valid test output but just
doesn't execute any test, for example in conditional compilations:
\snippet doc/src/snippets/code/src_qtestlib_qtestcase.cpp 12
\sa QTEST_MAIN()
*/
/*!
\macro QBENCHMARK
\relates QTest
This macro is used to measure the performance of code within a test.
The code to be benchmarked is contained within a code block following
this macro.
For example:
\snippet examples/qtestlib/tutorial5/benchmarking.cpp 0
\sa {QTestLib Manual#Creating a Benchmark}{Creating a Benchmark},
{Chapter 5: Writing a Benchmark}{Writing a Benchmark}
*/
/*! \enum QTest::SkipMode
This enum describes the modes for skipping tests during execution
of the test data.
\value SkipSingle Skips the current entry in the test table; continues
execution of all the other entries in the table.
\value SkipAll Skips all the entries in the test table; the test won't
be executed further.
\sa QSKIP()
*/
/*! \enum QTest::TestFailMode
This enum describes the modes for handling an expected failure of the
\l QVERIFY() or \l QCOMPARE() macros.
\value Abort Aborts the execution of the test. Use this mode when it
doesn't make sense to execute the test any further after the
expected failure.
\value Continue Continues execution of the test after the expected failure.
\sa QEXPECT_FAIL()
*/
/*! \enum QTest::KeyAction
This enum describes possible actions for key handling.
\value Press The key is pressed.
\value Release The key is released.
\value Click The key is clicked (pressed and released).
*/
/*! \enum QTest::MouseAction
This enum describes possible actions for mouse handling.
\value MousePress A mouse button is pressed.
\value MouseRelease A mouse button is released.
\value MouseClick A mouse button is clicked (pressed and released).
\value MouseDClick A mouse button is double clicked (pressed and released twice).
\value MouseMove The mouse pointer has moved.

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}:

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
