@ -102,30 +102,40 @@ To make sure your changes work as intended and don't break existing
functionality, you'll want to compile and run Google Test and GoogleMock's own
tests. For that you can use CMake:
mkdir mybuild
cd mybuild
cmake -Dgtest_build_tests=ON -Dgmock_build_tests=ON ${GTEST_REPO_DIR}
```
mkdir mybuild
cd mybuild
cmake -Dgtest_build_tests=ON -Dgmock_build_tests=ON ${GTEST_REPO_DIR}
```
To choose between building only Google Test or Google Mock, you may modify your
cmake command to be one of each
cmake -Dgtest_build_tests=ON ${GTEST_DIR} # sets up Google Test tests
cmake -Dgmock_build_tests=ON ${GMOCK_DIR} # sets up Google Mock tests
```
cmake -Dgtest_build_tests=ON ${GTEST_DIR} # sets up Google Test tests
cmake -Dgmock_build_tests=ON ${GMOCK_DIR} # sets up Google Mock tests
```
Make sure you have Python installed, as some of Google Test's tests are written
in Python. If the cmake command complains about not being able to find Python
(`Could NOT find PythonInterp (missing: PYTHON_EXECUTABLE)`), try telling it
explicitly where your Python executable can be found:
cmake -DPYTHON_EXECUTABLE=path/to/python ...
```
cmake -DPYTHON_EXECUTABLE=path/to/python ...
```
Next, you can build Google Test and / or Google Mock and all desired tests. On
\*nix, this is usually done by
make
```
make
```
To run the tests, do
make test
```
make test
```
All tests should pass.

As mentioned earlier, the printer is *extensible*. That means you can teach it
to do a better job at printing your particular type than to dump the bytes. To
do that, define `<<` for your type:
```c++
#include <ostream>
do that, define an `AbslStringify()` overload as a `friend` function template
for your type:
```cpp
namespace foo {
class Bar { // We want googletest to be able to print instances of this.
...
// Create a free inline friend function.
friend std::ostream& operator<<(std::ostream& os, const Bar& bar) {
return os << bar.DebugString(); // whatever needed to print bar to os
class Point { // We want GoogleTest to be able to print instances of this.
...
// Provide a friend overload.
template <typename Sink>
friend void AbslStringify(Sink& sink, const Point& point) {
absl::Format(&sink, "(%d, %d)", point.x, point.y);
}
int x;
int y;
};
// If you can't declare the function in the class it's important that the
// << operator is defined in the SAME namespace that defines Bar. C++'s look-up
// rules rely on that.
std::ostream& operator<<(std::ostream& os, const Bar& bar) {
return os << bar.DebugString(); // whatever needed to print bar to os
// AbslStringify overload is defined in the SAME namespace that defines Point.
// C++'s look-up rules rely on that.
enum class EnumWithStringify { kMany = 0, kChoices = 1 };
template <typename Sink>
void AbslStringify(Sink& sink, EnumWithStringify e) {
absl::Format(&sink, "%s", e == EnumWithStringify::kMany ? "Many" : "Choices");
}
} // namespace foo
```
Sometimes, this might not be an option: your team may consider it bad style to
have a `<<` operator for `Bar`, or `Bar` may already have a `<<` operator that
doesn't do what you want (and you cannot change it). If so, you can instead
define a `PrintTo()` function like this:
{: .callout .note}
Note: `AbslStringify()` utilizes a generic "sink" buffer to construct its
string. For more information about supported operations on `AbslStringify()`'s
sink, see go/abslstringify.
`AbslStringify()` can also use `absl::StrFormat`'s catch-all `%v` type specifier
within its own format strings to perform type deduction. `Point` above could be
formatted as `"(%v, %v)"` for example, and deduce the `int` values as `%d`.
Sometimes, `AbslStringify()` might not be an option: your team may wish to print
types with extra debugging information for testing purposes only. If so, you can
instead define a `PrintTo()` function like this:
```c++
#include <ostream>
namespace foo {
class Bar {
class Point {
...
friend void PrintTo(const Bar& bar, std::ostream* os) {
*os << bar.DebugString(); // whatever needed to print bar to os
friend void PrintTo(const Point& point, std::ostream* os) {
*os << "(" << point.x << "," << point.y << ")";
}
int x;
int y;
};
// If you can't declare the function in the class it's important that PrintTo()
// is defined in the SAME namespace that defines Bar. C++'s look-up rules rely
// on that.
void PrintTo(const Bar& bar, std::ostream* os) {
*os << bar.DebugString(); // whatever needed to print bar to os
// is defined in the SAME namespace that defines Point. C++'s look-up rules
// rely on that.
void PrintTo(const Point& point, std::ostream* os) {
*os << "(" << point.x << "," << point.y << ")";
}
} // namespace foo
```
If you have defined both `<<` and `PrintTo()`, the latter will be used when
googletest is concerned. This allows you to customize how the value appears in
googletest's output without affecting code that relies on the behavior of its
`<<` operator.

If you have an existing `<<` operator and would like to define an
`AbslStringify()`, the latter will be used for GoogleTest printing.
If you want to print a value `x` using GoogleTest's value printer yourself, just
call `::testing::PrintToString(x)`, which returns an `std::string`:
```c++
vector<pair<Bar, int> > bar_ints = GetBarIntVector();
vector<pair<Point, int> > point_ints = GetPointIntVector();
EXPECT_TRUE(IsCorrectBarIntVector(bar_ints))
<< "bar_ints = " << testing::PrintToString(bar_ints);
EXPECT_TRUE(IsCorrectPointIntVector(point_ints))
<< "point_ints = " << testing::PrintToString(point_ints);

libraries, see go/abslstringify.

1. In your test fixture class (say `FooTest` ), declare as `static` some member
variables to hold the shared resources.
2. Outside your test fixture class (typically just below it), define those
member variables, optionally giving them initial values.
3. In the same test fixture class, define a `static void SetUpTestSuite()`
function (remember not to spell it as **`SetupTestSuite`** with a small
`u`!) to set up the shared resources and a `static void TearDownTestSuite()`
function to tear them down.
3. In the same test fixture class, define a public member function `static void

Now, when `RUN_ALL_TESTS()` is called, it first calls the `SetUp()` method of

Now, when `RUN_ALL_TESTS()` is invoked, it first calls the `SetUp()` method. The

fatal failures and `GTEST_SKIP()` has not been invoked. Finally, `TearDown()` is

Note that `SetUp()` and `TearDown()` are only invoked if there is at least one
test to be performed. Importantly, `TearDown()` is executed even if the test is
not run due to a fatal failure or `GTEST_SKIP()`.
Calling `SetUp()` and `TearDown()` for each iteration depends on the flag

**Note:** `ProtocolMessageEquals` and `ProtocolMessageEquiv` are *deprecated*
now. Please use `EqualsProto`, etc instead.
`ProtocolMessageEquals` and `ProtocolMessageEquiv` were redefined recently and
are now less tolerant of invalid protocol buffer definitions. In particular, if
you have a `foo.proto` that doesn't fully qualify the type of a protocol message
it references (e.g. `message<Bar>` where it should be `message<blah.Bar>`), you
will now get run-time errors like:
```
... descriptor.cc:...] Invalid proto descriptor for file "path/to/foo.proto":
... descriptor.cc:...] blah.MyMessage.my_field: ".Bar" is not defined.

the types fully qualified. The new definition of `ProtocolMessageEquals` and

GoogleTest is thread-safe where the pthread library is available. After

`GTEST_IS_THREADSAFE` macro to see whether this is the case (yes if the macro is
