nested autoconf package rather than as raw source. This way we can trivially update it again in the future. Actually, this change doesn't even include gtest in protobuf's SVN. Instead, we auto-download it when autogen.sh is invoked. Note that it will be included in release distributions, though. TODO: * Add a configure option to use the system's installed gtest rather than the bundled copy. Apparently the gtest maintainers are working on some general-purpose autoconf macros which will do this automagically. * Update MSVC project files.pull/3335/head

This directory contains Google Test, described below. It is used by the |
||||
Protocol Buffer C++ unit tests. If you would like to use Google Test |
||||
yourself, you should probably download it from the URL mentioned below, |
||||
not attempt to use the sources in this package. |
||||
|
||||
Two changes were made from the original sources: |
||||
* gtest.cc's #include of gtest-internal-inl.h was modified to reflect the |
||||
environment it is being built in (replaced "src/" with "gtest/"). |
||||
* GetThreadCount() in gtest-port.h was hard-coded to return 1 rather than 0, |
||||
since the Protocol Buffer tests do not use threads. |
||||
|
||||
The original Google Test README follows. |

|
||||
Google C++ Testing Framework |
||||
============================ |
||||
http://code.google.com/p/googletest/ |
||||
|
||||
Overview |
||||
-------- |
||||
Google's framework for writing C++ tests on a variety of platforms (Linux, Mac |
||||
OS X, Windows, Windows CE, and Symbian). Based on the xUnit architecture. |
||||
Supports automatic test discovery, a rich set of assertions, user-defined |
||||
assertions, death tests, fatal and non-fatal failures, various options for |
||||
running the tests, and XML test report generation. |
||||
|
||||
Please see the project page above for more information as well as mailing lists |
||||
for questions, discussions, and development. There is also an IRC channel on |
||||
OFTC (irc.oftc.net) #gtest available. Please join us! |
||||
|
||||
Requirements |
||||
------------ |
||||
Google Test is designed to have fairly minimal requirements to build and use |
||||
with your projects, but there are some. Currently, the only Operating System |
||||
(OS) on which Google Test is known to build properly is Linux, but we are |
||||
actively working on Windows and Mac support as well. The source code itself is |
||||
already portable across many other platforms, but we are still developing |
||||
robust build systems for each. |
||||
|
||||
### Linux Requirements ### |
||||
These are the base requirements to build and use Google Test from a source |
||||
package (as described below): |
||||
* GNU-compatible Make or "gmake" |
||||
* POSIX-standard shell |
||||
* POSIX(-2) Regular Expressions (regex.h) |
||||
* A C++98 standards compliant compiler |
||||
|
||||
Furthermore, if you are building Google Test from a VCS Checkout (also |
||||
described below), there are further requirements: |
||||
* Automake version 1.9 or newer |
||||
* Autoconf version 2.59 or newer |
||||
* Libtool / Libtoolize |
||||
* Python version 2.4 or newer |
||||
|
||||
Getting the Source |
||||
------------------ |
||||
There are two primary ways of getting Google Test's source code: you can |
||||
download a source release in your preferred archive format, or directly check |
||||
out the source from a Version Control System (VCS, we use Google Code's |
||||
Subversion hosting). The VCS checkout requires a few extra steps and some extra |
||||
software packages on your system, but lets you track development, and make |
||||
patches to contribute much more easily, so we highly encourage it. |
||||
|
||||
### VCS Checkout: ### |
||||
The first step is to select whether you want to check out the main line of |
||||
development on Google Test, or one of the released branches. The former will be |
||||
much more active and have the latest features, but the latter provides much |
||||
more stability and predictability. Choose whichever fits your needs best, and |
||||
proceed with the following Subversion commands: |
||||
|
||||
$ svn checkout http://googletest.googlecode.com/svn/trunk/ gtest-svn |
||||
|
||||
or for a release version X.Y.*'s branch: |
||||
|
||||
$ svn checkout http://googletest.googlecode.com/svn/branches/release-X.Y/ gtest-X.Y-svn |
||||
|
||||
Next you will need to prepare the GNU Autotools build system. Enter the |
||||
target directory of the checkout command you used ('gtest-svn' or |
||||
'gtest-X.Y-svn' above) and proceed with the following commands: |
||||
|
||||
$ aclocal-1.9 # Where "1.9" must match the following automake command |
||||
$ libtoolize -c |
||||
$ autoheader |
||||
$ automake-1.9 -ac # See Automake version requirements above |
||||
$ autoconf |
||||
|
||||
While this is a bit complicated, it will most often be automatically re-run by |
||||
your "make" invocations, so in practice you shouldn't need to worry too much. |
||||
Once you have completed these steps, your VCS checkout should be equivalent to |
||||
a source package, and you may continue with those directions, skipping over the |
||||
acquiring and unpacking of the source itself, as the VCS has done that for you. |
||||
|
||||
### Source Package: ### |
||||
Google Test is also released in source packages which can be downloaded from |
||||
its Google Code download page[1]. Several different archive formats are |
||||
provided, but the only difference is the tools used to manipulate them, and the |
||||
size of the resulting file. Download whichever you are most comfortable with. |
||||
|
||||
[1] Google Test Downloads: http://code.google.com/p/googletest/downloads/list |
||||
|
||||
Once downloaded expand the archive using whichever tools you prefer for that |
||||
type. This will always result in a new directory with the name "gtest-X.Y.Z" |
||||
which contains all of the source code. Here are some examples in Linux: |
||||
|
||||
$ tar -xvzf gtest-X.Y.Z.tar.gz |
||||
$ tar -xvjf gtest-X.Y.Z.tar.bz2 |
||||
$ unzip gtest-X.Y.Z.zip |
||||
|
||||
Building the Source |
||||
------------------- |
||||
There are two primary options for building the source at this point: build it |
||||
inside the source code tree, or in a separate directory. We recommend building |
||||
in a separate directory as that tends to produce both more consistent results |
||||
and be easier to clean up should anything go wrong, but both patterns are |
||||
supported. The only hard restriction is that while the build directory can be |
||||
a subdirectory of the source directory, the opposite is not possible and will |
||||
result in errors. Once you have selected where you wish to build Google Test, |
||||
create the directory if necessary, and enter it. The following steps apply for |
||||
either approach by simply substituting the shell variable SRCDIR with "." for |
||||
building inside the source directory, and the relative path to the source |
||||
directory otherwise. |
||||
|
||||
$ ${SRCDIR}/configure # Standard GNU configure script, --help for more info |
||||
$ make # Standard makefile following GNU conventions |
||||
|
||||
Other programs will only be able to use Google Test's functionality if you |
||||
install it in a location which they can access, in Linux this is typically |
||||
under '/usr/local'. The following command will install all of the Google Test |
||||
libraries, public headers, and utilities necessary for other programs and |
||||
libraries to leverage it: |
||||
|
||||
$ sudo make install # Not necessary, but allows use by other programs |
||||
|
||||
TODO(chandlerc@google.com): This section needs to be expanded when the |
||||
'gtest-config' script is finished and Autoconf macro's are provided (or not |
||||
provided) in order to properly reflect the process for other programs to |
||||
locate, include, and link against Google Test. |
||||
|
||||
Finally, should you need to remove Google Test from your system after having |
||||
installed it, run the following command, and it will back out its changes. |
||||
However, note carefully that you must run this command on the *same* Google |
||||
Test build that you ran the install from, or the results are not predictable. |
||||
If you install Google Test on your system, and are working from a VCS checkout, |
||||
make sure you run this *before* updating your checkout of the source in order |
||||
to uninstall the same version which you installed. |
||||
|
||||
$ sudo make uninstall # Must be run against the exact same build as "install" |
||||
|
||||
Happy testing! |

// The following macros are useful for writing death tests.
|

|

// Here's what happens when an ASSERT_DEATH* or EXPECT_DEATH* is
|
||||
// executed:
|
||||
//
|
||||
// 1. The assertion fails immediately if there are more than one
|
||||
// active threads. This is because it's safe to fork() only when
|
||||
// there is a single thread.
|
||||
//
|
||||
// 2. The parent process forks a sub-process and runs the death test
|
||||
// in it; the sub-process exits with code 0 at the end of the death
|
||||
// test, if it hasn't exited already.
|
||||
//
|
||||
// 3. The parent process waits for the sub-process to terminate.
|
||||
//
|
||||
// 4. The parent process checks the exit code and error message of
|
||||
// the sub-process.
|
||||
//
|
||||
// Note:
|
||||
//
|
||||
// It's not safe to call exit() if the current process is forked from
|
||||
// a multi-threaded process, so people usually call _exit() instead in
|
||||
// such a case. However, we are not concerned with this as we run
|
||||
// death tests only when there is a single thread. Since exit() has a
|
||||
// cleaner semantics (it also calls functions registered with atexit()
|
||||
// and on_exit()), this macro calls exit() instead of _exit() to
|
||||
// terminate the child process.
|
||||
//
|
||||

|

//
|

// ASSERT_DEATH(server.SendMessage(56, "Hello"), "Invalid port number");

// Typical usage:

//
|

// 1. You stream a bunch of values to a Message object.
|
||||
// It will remember the text in a StrStream.
|
||||
// 2. Then you stream the Message object to an ostream.
|
||||
// This causes the text in the Message to be streamed
|
||||
// to the ostream.
|
||||
//
|
||||
// For example;
|
||||
//
|
||||
// testing::Message foo;
|
||||
// foo << 1 << " != " << 2;
|
||||
// std::cout << foo;
|

//
|
||||
// will print "1 != 2".
|
||||
//
|
||||
// Message is not intended to be inherited from. In particular, its
|
||||
// destructor is not virtual.
|
||||
//
|
||||
// Note that StrStream behaves differently in gcc and in MSVC. You
|
||||
// can stream a NULL char pointer to it in the former, but not in the
|
||||
// latter (it causes an access violation if you do). The Message
