-    \section1 Building and Running Autotests
+    \section1 Setting Up the Google C++ Testing Framework
 
-    To build and run autotests:
+    To build and run Google tests, you must have the Google C++ Testing
+    framework installed and configured on the development host. You can either
+    clone it from Git Hub or install it from an installation package.
+
+    To configure a project to use a cloned Google testing framework, edit the
+    \c INCLUDEPATH variable in the project file (.pro) to include the source
+    and \c include folders of Google Test's \c googletest and \c googlemock.
+    Usually, you need to add the following subfolders:
+
+    \list
+        \li \c googletest
+        \li \c googlemock
+        \li \c googletest/include
+        \li \c googlemock/include
+    \endlist
+
+    You also need to add the necessary files to the \c SOURCES variable. For
+    example:
+
+    \list
+        \li \c googletest/src/gtest-all.cc
+        \li \c googlemock/src/gmock-all.cc
+    \endlist
+
+    To configure a project to use an installed Google testing framework package,
+    add the following include paths to the .pro file:
+
+    \list
+        \li \c <googletest_install_path>/include/gtest
+        \li \c <googletest_install_path>/include/gmock
+    \endlist
+
+    Then add linker options to be able to find the libraries and to link against
+    them. For example, for qmake based projects, you typically need to add the
+    following values to the .pro file:
+
+    \list
+        \li \c {LIBS += -lgtest -L<path_to_gtest_lib>}
+        \li \c {LIBS += -lgmock -L<path_to_gmock_lib>}
+    \endlist
+
+    To specify settings for running Google tests, select \uicontrol Tools >
+    \uicontrol Options > \uicontrol {Test Settings}.
+
+    \image qtcreator-autotests-options.png
+
+    To run disabled tests, select the \uicontrol {Run disabled tests} check box.
+
+    To run several iterations of the tests, select the \uicontrol {Repeat tests}
+    check box and enter the number of times the tests should be run in the
+    \uicontrol Iterations field. To make sure that the tests are independent and
+    repeatable, you can run them in a different order each time by selecting the
+    \uicontrol {Shuffle tests} check box.
+
