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, you are ready to build the library.
### 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
$ make check # Builds and runs all tests - all should pass
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!

GTEST_DECLARE_string(death_test_style);
#ifdef GTEST_HAS_DEATH_TEST
// 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.
//
// Examples:
//
// ASSERT_DEATH(server.SendMessage(56, "Hello"), "Invalid port number");
// for (int i = 0; i < 5; i++) {
// EXPECT_DEATH(server.ProcessRequest(i),
// "Invalid request .* in ProcessRequest()")
// << "Failed to die on request " << i);
// }
//
// ASSERT_EXIT(server.ExitNow(), ::testing::ExitedWithCode(0), "Exiting");
//
// bool KilledBySIGHUP(int exit_code) {
// return WIFSIGNALED(exit_code) && WTERMSIG(exit_code) == SIGHUP;
// }
//
// ASSERT_EXIT(client.HangUpServer(), KilledBySIGHUP, "Hanging up!");
// Asserts that a given statement causes the program to exit, with an
// integer exit status that satisfies predicate, and emitting error output
// that matches regex.
#define ASSERT_EXIT(statement, predicate, regex) \
GTEST_DEATH_TEST(statement, predicate, regex, GTEST_FATAL_FAILURE)
// Like ASSERT_EXIT, but continues on to successive tests in the
// test case, if any:
#define EXPECT_EXIT(statement, predicate, regex) \
GTEST_DEATH_TEST(statement, predicate, regex, GTEST_NONFATAL_FAILURE)
// Asserts that a given statement causes the program to exit, either by
// explicitly exiting with a nonzero exit code or being killed by a
// signal, and emitting error output that matches regex.
#define ASSERT_DEATH(statement, regex) \
ASSERT_EXIT(statement, ::testing::internal::ExitedUnsuccessfully, regex)
// Like ASSERT_DEATH, but continues on to successive tests in the
// test case, if any:
#define EXPECT_DEATH(statement, regex) \
EXPECT_EXIT(statement, ::testing::internal::ExitedUnsuccessfully, regex)
// Two predicate classes that can be used in {ASSERT,EXPECT}_EXIT*:
// Tests that an exit code describes a normal exit with a given exit code.

class KilledBySignal {
public:
explicit KilledBySignal(int signum);
bool operator()(int exit_status) const;
private:

};
// EXPECT_DEBUG_DEATH asserts that the given statements die in debug mode.
// The death testing framework causes this to have interesting semantics,
// since the sideeffects of the call are only visible in opt mode, and not
// in debug mode.
//
// In practice, this can be used to test functions that utilize the
// LOG(DFATAL) macro using the following style:
//
// int DieInDebugOr12(int* sideeffect) {
// if (sideeffect) {
// *sideeffect = 12;

// // Only asserts in dbg.

//

// // opt-mode has sideeffect visible.
// EXPECT_EQ(12, sideeffect);
// #else
// // dbg-mode no visible sideeffect.

// The Message class works like an ostream repeater.
//
// 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
// class hides this difference by treating a NULL char pointer as
// "(null)".

// A sample program demonstrating using Google C++ testing framework.
//
// Author: wan@google.com (Zhanyong Wan)
// This sample shows how to write a simple unit test for a function,
// using Google C++ testing framework.
//
// Writing a unit test using Google C++ testing framework is easy as 1-2-3:
// Step 1. Include necessary header files such that the stuff your
// test logic needs is declared.
//
// Don't forget gtest.h, which declares the testing framework.
#include <limits.h>
#include "sample1.h"
#include <gtest/gtest.h>
// Step 2. Use the TEST macro to define your tests.
//
// TEST has two parameters: the test case name and the test name.
// After using the macro, you should define your test logic between a
// pair of braces. You can use a bunch of macros to indicate the
// success or failure of a test. EXPECT_TRUE and EXPECT_EQ are
// examples of such macros. For a complete list, see gtest.h.
//
// <TechnicalDetails>
//
// In Google Test, tests are grouped into test cases. This is how we
// keep test code organized. You should put logically related tests
// into the same test case.
//
// The test case name and the test name should both be valid C++
// identifiers. And you should not use underscore (_) in the names.
//
// Google Test guarantees that each test you define is run exactly
// once, but it makes no guarantee on the order the tests are
// executed. Therefore, you should write your tests in such a way
// that their results don't depend on their order.
//
// </TechnicalDetails>
// Tests Factorial().
// Tests factorial of negative numbers.
TEST(FactorialTest, Negative) {
// This test is named "Negative", and belongs to the "FactorialTest"
// test case.
EXPECT_EQ(1, Factorial(-5));
EXPECT_EQ(1, Factorial(-1));
EXPECT_TRUE(Factorial(-10) > 0);
// <TechnicalDetails>
//
// EXPECT_EQ(expected, actual) is the same as
//
// EXPECT_TRUE((expected) == (actual))
//
// except that it will print both the expected value and the actual
// value when the assertion fails. This is very helpful for
// debugging. Therefore in this case EXPECT_EQ is preferred.
//
// On the other hand, EXPECT_TRUE accepts any Boolean expression,
// and is thus more general.
//
// </TechnicalDetails>
}
// Tests factorial of 0.
TEST(FactorialTest, Zero) {
EXPECT_EQ(1, Factorial(0));
}
// Tests factorial of positive numbers.
TEST(FactorialTest, Positive) {
EXPECT_EQ(1, Factorial(1));
EXPECT_EQ(2, Factorial(2));
EXPECT_EQ(6, Factorial(3));
EXPECT_EQ(40320, Factorial(8));
}
// Tests IsPrime()
// Tests negative input.
TEST(IsPrimeTest, Negative) {
// This test belongs to the IsPrimeTest test case.
EXPECT_FALSE(IsPrime(-1));
EXPECT_FALSE(IsPrime(-2));
EXPECT_FALSE(IsPrime(INT_MIN));
}
// Tests some trivial cases.
TEST(IsPrimeTest, Trivial) {
EXPECT_FALSE(IsPrime(0));
EXPECT_FALSE(IsPrime(1));
EXPECT_TRUE(IsPrime(2));
EXPECT_TRUE(IsPrime(3));
}
// Tests positive input.
TEST(IsPrimeTest, Positive) {
EXPECT_FALSE(IsPrime(4));
EXPECT_TRUE(IsPrime(5));
EXPECT_FALSE(IsPrime(6));
EXPECT_TRUE(IsPrime(23));
}
// Step 3. Call RUN_ALL_TESTS() in main().
//
// We do this by linking in src/gtest_main.cc file, which consists of
// a main() function which calls RUN_ALL_TESTS() for us.
//
// This runs all the tests you've defined, prints the result, and
// returns 0 if successful, or 1 otherwise.
//
// Did you notice that we didn't register the tests? The
// RUN_ALL_TESTS() macro magically knows about all the tests we
// defined. Isn't this convenient?

// In this example, we use a more advanced feature of Google Test called
// test fixture.
//
// A test fixture is a place to hold objects and functions shared by
// all tests in a test case. Using a test fixture avoids duplicating
// the test code necessary to initialize and cleanup those common
// objects for each test. It is also useful for defining sub-routines
// that your tests need to invoke a lot.
//
// <TechnicalDetails>
//
// The tests share the test fixture in the sense of code sharing, not
// data sharing. Each test is given its own fresh copy of the
// fixture. You cannot expect the data modified by one test to be
// passed on to another test, which is a bad idea.
//
// The reason for this design is that tests should be independent and
// repeatable. In particular, a test should not fail as the result of
// another test's failure. If one test depends on info produced by
// another test, then the two tests should really be one big test.
//
// The macros for indicating the success/failure of a test
// (EXPECT_TRUE, FAIL, etc) need to know what the current test is
// (when Google Test prints the test result, it tells you which test
// each failure belongs to). Technically, these macros invoke a
// member function of the Test class. Therefore, you cannot use them
// in a global function. That's why you should put test sub-routines
// in a test fixture.

// This sample teaches how to reuse a test fixture in multiple test
// cases by deriving sub-fixtures from it.
//
// When you define a test fixture, you specify the name of the test
// case that will use this fixture. Therefore, a test fixture can
// be used by only one test case.
//
// Sometimes, more than one test cases may want to use the same or
// slightly different test fixtures. For example, you may want to
// make sure that all tests for a GUI library don't leak important
// system resources like fonts and brushes. In Google Test, you do
// this by putting the shared logic in a super (as in "super class")
// test fixture, and then have each test case use a fixture derived
// from this super fixture.
#include <limits.h>
#include <time.h>
#include "sample3-inl.h"
#include <gtest/gtest.h>
#include "sample1.h"
// In this sample, we want to ensure that every test finishes within
// ~5 seconds. If a test takes longer to run, we consider it a
// failure.
//
// We put the code for timing a test in a test fixture called
// "QuickTest". QuickTest is intended to be the super fixture that
// other fixtures derive from, therefore there is no test case with
// the name "QuickTest". This is OK.
//
// Later, we will derive multiple test fixtures from QuickTest.
class QuickTest : public testing::Test {
protected:
// Remember that SetUp() is run immediately before a test starts.
// This is a good place to record the start time.
virtual void SetUp() {
start_time_ = time(NULL);
}
// TearDown() is invoked immediately after a test finishes. Here we
// check if the test was too slow.
virtual void TearDown() {
// Gets the time when the test finishes
const time_t end_time = time(NULL);
// Asserts that the test took no more than ~5 seconds. Did you
// know that you can use assertions in SetUp() and TearDown() as
// well?
EXPECT_TRUE(end_time - start_time_ <= 5) << "The test took too long.";
}
// The UTC time (in seconds) when the test starts
time_t start_time_;
};
// We derive a fixture named IntegerFunctionTest from the QuickTest
// fixture. All tests using this fixture will be automatically
// required to be quick.
class IntegerFunctionTest : public QuickTest {
// We don't need any more logic than already in the QuickTest fixture.
// Therefore the body is empty.
};
// Now we can write tests in the IntegerFunctionTest test case.
// Tests Factorial()
TEST_F(IntegerFunctionTest, Factorial) {
// Tests factorial of negative numbers.
EXPECT_EQ(1, Factorial(-5));
EXPECT_EQ(1, Factorial(-1));
EXPECT_TRUE(Factorial(-10) > 0);
// Tests factorial of 0.
EXPECT_EQ(1, Factorial(0));
// Tests factorial of positive numbers.
EXPECT_EQ(1, Factorial(1));
EXPECT_EQ(2, Factorial(2));
EXPECT_EQ(6, Factorial(3));
EXPECT_EQ(40320, Factorial(8));
}
// Tests IsPrime()
TEST_F(IntegerFunctionTest, IsPrime) {
// Tests negative input.
EXPECT_TRUE(!IsPrime(-1));
EXPECT_TRUE(!IsPrime(-2));
EXPECT_TRUE(!IsPrime(INT_MIN));
// Tests some trivial cases.
EXPECT_TRUE(!IsPrime(0));
EXPECT_TRUE(!IsPrime(1));
EXPECT_TRUE(IsPrime(2));
EXPECT_TRUE(IsPrime(3));
// Tests positive input.
EXPECT_TRUE(!IsPrime(4));
EXPECT_TRUE(IsPrime(5));
EXPECT_TRUE(!IsPrime(6));
EXPECT_TRUE(IsPrime(23));
}
// The next test case (named "QueueTest") also needs to be quick, so
// we derive another fixture from QuickTest.
//
// The QueueTest test fixture has some logic and shared objects in
// addition to what's in QuickTest already. We define the additional
// stuff inside the body of the test fixture, as usual.
class QueueTest : public QuickTest {
protected:
virtual void SetUp() {
// First, we need to set up the super fixture (QuickTest).
QuickTest::SetUp();
// Second, some additional setup for this fixture.
q1_.Enqueue(1);
q2_.Enqueue(2);
q2_.Enqueue(3);
}
// By default, TearDown() inherits the behavior of
// QuickTest::TearDown(). As we have no additional cleaning work
// for QueueTest, we omit it here.
//
// virtual void TearDown() {
// QuickTest::TearDown();
// }
Queue<int> q0_;
Queue<int> q1_;
Queue<int> q2_;
};
// Now, let's write tests using the QueueTest fixture.
// Tests the default constructor.
TEST_F(QueueTest, DefaultConstructor) {
EXPECT_EQ(0, q0_.Size());
}
// Tests Dequeue().
TEST_F(QueueTest, Dequeue) {
int * n = q0_.Dequeue();
EXPECT_TRUE(n == NULL);
n = q1_.Dequeue();
EXPECT_TRUE(n != NULL);
EXPECT_EQ(1, *n);
EXPECT_EQ(0, q1_.Size());
delete n;
n = q2_.Dequeue();
EXPECT_TRUE(n != NULL);
EXPECT_EQ(2, *n);
EXPECT_EQ(1, q2_.Size());
delete n;
}
// If necessary, you can derive further test fixtures from a derived
// fixture itself. For example, you can derive another fixture from
// QueueTest. Google Test imposes no limit on how deep the hierarchy
// can be. In practice, however, you probably don't want it to be too
// deep as to be confusing.

The \`gtest-config' script provides access to the necessary compile and linking
flags to connect with Google C++ Testing framework. The installation queries
may only be issued one at a time, and may not be issued with any other types of
queries. The version queries and compiler flag queries may be combined as
desired but not mixed. Different version queries are always combined with "and"
logical semantics, and only the last of any particular query is used and all
previous ones ignored. All versions must be specified as a sequence of numbers
separated by periods. Compiler flag queries output the union of the sets of
flags when combined.
Examples:
gtest-config --min-version=1.0 || echo "Insufficient Google Test version."
gcc \$(gtest-config --cppflags --cxxflags) -o foo.o -c foo.cpp
gcc \$(gtest-config --ldflags --libs) -o foo foo.o
Help:
--usage brief usage information
--help display this help message
Installation Queries:
--prefix installation prefix
--exec-prefix executable installation prefix
--libdir library installation directory
--includedir header file installation directory
--version the version of the INC installation
Version Queries:
--min-version=VERSION return 0 if the version is at least VERSION
--exact-version=VERSION return 0 if the version is exactly VERSION
--max-version=VERSION return 0 if the version is at most VERSION
Compilation Flag Queries:
--cppflags compile flags specific to the C-like preprocessors
--cxxflags compile flags appropriate for C++ programs
--ldflags linker flags
--libs libraries for linking
