@ -102,40 +102,30 @@ 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.

### Announcements
#### Live at Head
GoogleTest now follows the
[Abseil Live at Head philosophy](https://abseil.io/about/philosophy#upgrade-support).
We recommend
[updating to the latest commit in the `main` branch as often as possible](https://github.com/abseil/abseil-cpp/blob/master/FAQ.md#what-is-live-at-head-and-how-do-i-do-it).
#### Documentation Updates
Our documentation is now live on GitHub Pages at
https://google.github.io/googletest/. We recommend browsing the documentation on
GitHub Pages rather than directly in the repository.
#### Release 1.17.0
#### Release 1.12.1
[Release 1.17.0](https://github.com/google/googletest/releases/tag/v1.17.0) is
now available.
[Release 1.12.1](https://github.com/google/googletest/releases/tag/release-1.12.1)
is now available.
The 1.17.x branch
[requires at least C++17](https://opensource.google/documentation/policies/cplusplus-support#c_language_standard).
#### Continuous Integration
We use Google's internal systems for continuous integration.
The 1.12.x branch will be the last to support C++11. Future releases will
require at least C++14.
#### Coming Soon
* We are planning to take a dependency on
[Abseil](https://github.com/abseil/abseil-cpp).
* More documentation improvements are planned.

## Features
* xUnit test framework: \
Googletest is based on the [xUnit](https://en.wikipedia.org/wiki/XUnit)
testing framework, a popular architecture for unit testing
* Test discovery: \
Googletest automatically discovers and runs your tests, eliminating the need
to manually register your tests
* Rich set of assertions: \
Googletest provides a variety of assertions, such as equality, inequality,
exceptions, and more, making it easy to test your code
* User-defined assertions: \
You can define your own assertions with Googletest, making it simple to
write tests that are specific to your code
* Death tests: \
Googletest supports death tests, which verify that your code exits in a
certain way, making it useful for testing error-handling code
* Fatal and non-fatal failures: \
You can specify whether a test failure should be treated as fatal or
non-fatal with Googletest, allowing tests to continue running even if a
failure occurs
* Value-parameterized tests: \
Googletest supports value-parameterized tests, which run multiple times with
different input values, making it useful for testing functions that take
different inputs
* Type-parameterized tests: \
Googletest also supports type-parameterized tests, which run with different
data types, making it useful for testing functions that work with different
data types
* Various options for running tests: \
Googletest provides many options for running tests including running
individual tests, running tests in a specific order and running tests in
parallel
* An [xUnit](https://en.wikipedia.org/wiki/XUnit) test framework.
* Test discovery.
* A rich set of assertions.
* User-defined assertions.
* Death tests.
* Fatal and non-fatal failures.
* Value-parameterized tests.
* Type-parameterized tests.
* Various options for running the tests.
* XML test report generation.

@ -315,143 +315,73 @@ prints the raw bytes in the value and hopes that you the user can figure it out.
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 an `AbslStringify()` overload as a `friend` function template
for your type:
```cpp
namespace foo {
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
// 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
```
{: .callout .note}
Note: `AbslStringify()` utilizes a generic "sink" buffer to construct its
string. For more information about supported operations on `AbslStringify()`'s
sink, see
[the `AbslStringify()` documentation](https://abseil.io/docs/cpp/guides/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:
do that, define `<<` for your type:
```c++
#include <ostream>
namespace foo {
class Point {
...
friend void PrintTo(const Point& point, std::ostream* os) {
*os << "(" << point.x << "," << point.y << ")";
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
}
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 Point. C++'s look-up rules
// rely on that.
void PrintTo(const Point& point, std::ostream* os) {
*os << "(" << point.x << "," << point.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
}
} // namespace foo
```
If you have defined both `AbslStringify()` and `PrintTo()`, the latter will be
used by GoogleTest. This allows you to customize how the value appears in
GoogleTest's output without affecting code that relies on the behavior of
`AbslStringify()`.
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:
If you have an existing `<<` operator and would like to define an
`AbslStringify()`, the latter will be used for GoogleTest printing.
```c++
#include <ostream>
If you want to print a value `x` using GoogleTest's value printer yourself, just
namespace foo {
class Bar {
...
friend void PrintTo(const Bar& bar, std::ostream* os) {
*os << bar.DebugString(); // whatever needed to print bar to os
}
};
// 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
}
} // 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 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<Point, int> > point_ints = GetPointIntVector();
vector<pair<Bar, int> > bar_ints = GetBarIntVector();
EXPECT_TRUE(IsCorrectPointIntVector(point_ints))
<< "point_ints = " << testing::PrintToString(point_ints);
EXPECT_TRUE(IsCorrectBarIntVector(bar_ints))
<< "bar_ints = " << testing::PrintToString(bar_ints);
```
For more details regarding `AbslStringify()` and its integration with other
libraries, see
[the documentation](https://abseil.io/docs/cpp/guides/abslstringify).
## Regular Expression Syntax
When built with Bazel and using Abseil, GoogleTest uses the
[RE2](https://github.com/google/re2/wiki/Syntax) syntax. Otherwise, for POSIX
systems (Linux, Cygwin, Mac), GoogleTest uses the
[POSIX extended regular expression](https://pubs.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap09.html#tag_09_04)
syntax. To learn about POSIX syntax, you may want to read this
[Wikipedia entry](https://en.wikipedia.org/wiki/Regular_expression#POSIX_extended).
On Windows, GoogleTest uses its own simple regular expression implementation. It
lacks many features. For example, we don't support union (`"x|y"`), grouping
(`"(xy)"`), brackets (`"[xy]"`), and repetition count (`"x{5,7}"`), among
others. Below is what we do support (`A` denotes a literal character, period
(`.`), or a single `\\ ` escape sequence; `x` and `y` denote regular
expressions.):
Expression | Meaning
---------- | --------------------------------------------------------------
`c` | matches any literal character `c`
`\\d` | matches any decimal digit
`\\D` | matches any character that's not a decimal digit
`\\f` | matches `\f`
`\\n` | matches `\n`
`\\r` | matches `\r`
`\\s` | matches any ASCII whitespace, including `\n`
`\\S` | matches any character that's not a whitespace
`\\t` | matches `\t`
`\\v` | matches `\v`
`\\w` | matches any letter, `_`, or decimal digit
`\\W` | matches any character that `\\w` doesn't match
`\\c` | matches any literal character `c`, which must be a punctuation
`.` | matches any single character except `\n`

### Regular Expression Syntax
When built with Bazel and using Abseil, googletest uses the
[RE2](https://github.com/google/re2/wiki/Syntax) syntax. Otherwise, for POSIX
systems (Linux, Cygwin, Mac), googletest uses the
[POSIX extended regular expression](http://www.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap09.html#tag_09_04)
syntax. To learn about POSIX syntax, you may want to read this
[Wikipedia entry](http://en.wikipedia.org/wiki/Regular_expression#POSIX_extended).
On Windows, googletest uses its own simple regular expression implementation. It
lacks many features. For example, we don't support union (`"x|y"`), grouping
(`"(xy)"`), brackets (`"[xy]"`), and repetition count (`"x{5,7}"`), among
others. Below is what we do support (`A` denotes a literal character, period
(`.`), or a single `\\ ` escape sequence; `x` and `y` denote regular
expressions.):
Expression | Meaning
---------- | --------------------------------------------------------------
`c` | matches any literal character `c`
`\\d` | matches any decimal digit
`\\D` | matches any character that's not a decimal digit
`\\f` | matches `\f`
`\\n` | matches `\n`
`\\r` | matches `\r`
`\\s` | matches any ASCII whitespace, including `\n`
`\\S` | matches any character that's not a whitespace
`\\t` | matches `\t`
`\\v` | matches `\v`
`\\w` | matches any letter, `_`, or decimal digit
`\\W` | matches any character that `\\w` doesn't match
`\\c` | matches any literal character `c`, which must be a punctuation
`.` | matches any single character except `\n`
`A?` | matches 0 or 1 occurrences of `A`
`A*` | matches 0 or many occurrences of `A`
`A+` | matches 1 or many occurrences of `A`
`^` | matches the beginning of a string (not that of each line)
`$` | matches the end of a string (not that of each line)
`xy` | matches `x` followed by `y`
To help you determine which capability is available on your system, googletest
defines macros to govern which regular expression it is using. The macros are:
`GTEST_USES_SIMPLE_RE=1` or `GTEST_USES_POSIX_RE=1`. If you want your death

variables to hold the shared resources.
2. Outside your test fixture class (typically just below it), define those

Now, when `RUN_ALL_TESTS()` is invoked, it first calls the `SetUp()` method. The
tests are then executed, provided that none of the environments have reported
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
`gtest_recreate_environments_when_repeating`. `SetUp()` and `TearDown()` are
called for each environment object when the object is recreated for each
iteration. However, if test environments are not recreated for each iteration,
`SetUp()` is called only on the first iteration, and `TearDown()` is called only

### Enforcing Having At Least One Test Case
A not uncommon programmer mistake is to write a test program that has no test
case linked in. This can happen, for example, when you put test case definitions
in a library and the library is not marked as "always link".
To catch such mistakes, run the test program with the
`--gtest_fail_if_no_test_linked` flag or set the `GTEST_FAIL_IF_NO_TEST_LINKED`
environment variable to a value other than `0`. Now the program will fail if no
test case is linked in.
Note that *any* test case linked in makes the program valid for the purpose of
this check. In particular, even a disabled test case suffices.
### Enforcing Running At Least One Test Case
In addition to enforcing that tests are defined in the binary with
`--gtest_fail_if_no_test_linked`, it is also possible to enforce that a test
case was actually executed to ensure that resources are not consumed by tests
that do nothing.
To catch such optimization opportunities, run the test program with the
`--gtest_fail_if_no_test_selected` flag or set the
`GTEST_FAIL_IF_NO_TEST_SELECTED` environment variable to a value other than `0`.
A test is considered selected if it begins to run, even if it is later skipped
via `GTEST_SKIP`. Thus, `DISABLED` tests do not count as selected and neither do
tests that are not matched by `--gtest_filter`.

## I got some run-time errors about invalid proto descriptors when using `ProtocolMessageEquals`. Help!

**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:...] blah.MyMessage.my_field: ".Bar" is not defined.

the types fully qualified. The new definition of `ProtocolMessageEquals` and
`ProtocolMessageEquiv` just happen to reveal your bug.

the thread you create joins the main thread, the thread count decrements by 1,

#### `MatchAndExplain`
You should let `MatchAndExplain()` print *any additional information* that can
help a user understand the match result. Note that it should explain why the
match succeeds in case of a success (unless it's obvious) - this is useful when

The type of the value being matched (`arg_type`) is determined by the context in
which you use the matcher and is supplied to you by the compiler, so you don't
need to worry about declaring it (nor can you). This allows the matcher to be
polymorphic. For example, `IsDivisibleBy7()` can be used to match any type where
the value of `(arg % 7) == 0` can be implicitly converted to a `bool`. In the
`Bar(IsDivisibleBy7())` example above, if method `Bar()` takes an `int`,
`arg_type` will be `int`; if it takes an `unsigned long`, `arg_type` will be
`unsigned long`; and so on.

of multiple types. For example, `Eq(5)` is a polymorhpic matcher as it can be
used to match an `int`, a `double`, a `float`, and so on. You should think of a
polymorphic matcher as a *matcher factory* as opposed to a
`testing::Matcher<SomeType>` - itself is not an actual matcher, but can be

Like in a monomorphic matcher, you may explain the match result by streaming
additional information to the `listener` argument in `MatchAndExplain()`.
### Implementing Composite Matchers {#CompositeMatchers}
Sometimes we want to define a matcher that takes other matchers as parameters.
For example, `DistanceFrom(target, m)` is a polymorphic matcher that takes a
matcher `m` as a parameter. It tests that the distance from `target` to the
value being matched satisfies sub-matcher `m`.
If you are implementing such a composite matcher, you'll need to generate the
description of the matcher based on the description(s) of its sub-matcher(s).
You can see the implementation of `DistanceFrom()` in
`googlemock/include/gmock/gmock-matchers.h` for an example. In particular, pay
attention to `DistanceFromMatcherImpl`. Notice that it stores the sub-matcher as
a `const Matcher<const Distance&> distance_matcher_` instead of a polymorphic
matcher - this allows it to call `distance_matcher_.DescribeTo(os)` to describe
the sub-matcher. If the sub-matcher is stored as a polymorphic matcher instead,
it would not be possible to get its description as in general polymorphic
matchers don't know how to describe themselves - they are matcher factories
instead of actual matchers; only after being converted to `Matcher<SomeType>`
can they be described.

###### Using `ConvertGenerator`
The functions listed in the table above appear to return generators that create
values of the desired types, but this is not generally the case. Rather, they
typically return factory objects that convert to the the desired generators.
This affords some flexibility in allowing you to specify values of types that
are different from, yet implicitly convertible to, the actual parameter type
required by your fixture class.
For example, you can do the following with a fixture that requires an `int`
parameter:
```cpp
INSTANTIATE_TEST_SUITE_P(MyInstantiation, MyTestSuite,
testing::Values(1, 1.2)); // Yes, Values() supports heterogeneous argument types.
```
It might seem obvious that `1.2` &mdash; a `double` &mdash; will be converted to
an `int` but in actuality it requires some template gymnastics involving the
indirection described in the previous paragraph.
What if your parameter type is not implicitly convertible from the generated
type but is *explicitly* convertible? There will be no automatic conversion, but
you can force it by applying `ConvertGenerator<T>`. The compiler can
automatically deduce the target type (your fixture's parameter type), but
because of the aforementioned indirection it cannot decide what the generated
type should be. You need to tell it, by providing the type `T` explicitly. Thus
`T` should not be your fixture's parameter type, but rather an intermediate type
that is supported by the factory object, and which can be `static_cast` to the
fixture's parameter type:
```cpp
// The fixture's parameter type.
class MyParam {
public:
// Explicit converting ctor.
explicit MyParam(const std::tuple<int, bool>& t);
...
};
INSTANTIATE_TEST_SUITE_P(MyInstantiation, MyTestSuite,
ConvertGenerator<std::tuple<int, bool>>(Combine(Values(0.1, 1.2), Bool())));
```
In this example `Combine` supports the generation of `std::tuple<int, bool>>`
objects (even though the provided values for the first tuple element are
`double`s) and those `tuple`s get converted into `MyParam` objects by virtue of
the call to `ConvertGenerator`.
For parameter types that are not convertible from the generated types you can
provide a callable that does the conversion. The callable accepts an object of
the generated type and returns an object of the fixture's parameter type. The
generated type can often be deduced by the compiler from the callable's call
signature so you do not usually need specify it explicitly (but see a caveat
below).
```cpp
// The fixture's parameter type.
class MyParam {
public:
MyParam(int, bool);
...
};
INSTANTIATE_TEST_SUITE_P(MyInstantiation, MyTestSuite,
ConvertGenerator(Combine(Values(1, 1.2), Bool()),
[](const std::tuple<int, bool>& t){
const auto [i, b] = t;
return MyParam(i, b);
}));
```
The callable may be anything that can be used to initialize a `std::function`
with the appropriate call signature. Note the callable's return object gets
`static_cast` to the fixture's parameter type, so it does not have to be of that
exact type, only convertible to it.
**Caveat:** Consider the following example.
```cpp
INSTANTIATE_TEST_SUITE_P(MyInstantiation, MyTestSuite,
ConvertGenerator(Values(std::string("s")), [](std::string_view s) { ... }));
```
The `string` argument gets copied into the factory object returned by `Values`.
Then, because the generated type deduced from the lambda is `string_view`, the
factory object spawns a generator that holds a `string_view` referencing that
`string`. Unfortunately, by the time this generator gets invoked, the factory
object is gone and the `string_view` is dangling.
To overcome this problem you can specify the generated type explicitly:
`ConvertGenerator<std::string>(Values(std::string("s")), [](std::string_view s)
{ ... })`. Alternatively, you can change the lambda's signature to take a
`std::string` or a `const std::string&` (the latter will not leave you with a
dangling reference because the type deduction strips off the reference and the
`const`).
