The CtorVsSetUp section of the FAQ says that constructors and destructors should be preferred over SetUp() and TearDown(), because they will automatically chain up to the fixture's base class, whereas for methods the user must remember to add the chaining manually.

* Applies for `std::index_sequence`, `std::make_index_sequence`, and `std::index_sequence_for` replacing `IndexSequence`, `MakeIndexSequence` and IndexSequenceFor`
* Also deleted implementation helper `DoubleSequence`
* The standard interfaces [have been in the standard library since C++14](https://en.cppreference.com/w/cpp/utility/integer_sequence), which [is the minimum supported C++ version by Google Test](https://github.com/google/oss-policies-info/blob/main/foundational-cxx-support-matrix.md)

during program exit
A race condition exist between the Watcher thread and main(). A case
was found where the Watcher thread does not get execution time before
the main function returns and calls atexit(). At that point the
Watcher thread started runing tls_init() code while the main thread
was shutting down. This resulted in rare crashes and deadlocks.

GoogleTest's tests do not currently compile when WINAPI_FAMILY is set to
anything else than WINAPI_FAMILY_DESKTOP_APP on Windows (if WINAPI_FAMILY is not
set explicitly, it will default to WINAPI_FAMILY_DESKTOP_APP).
Support for Xbox platforms, requires the code to support compilation with the
WINAPI_FAMILY_GAMES subset of the Win32 API.
- Add support for WINAPI_FAMILY_GAMES to enable GTEST_OS_WINDOWS_GAMES platform.
- Disable stream redirection (GTEST_HAS_STREAM_REDIRECTION = 0) and colored TTY
printing for GTEST_OS_WINDOWS_GAMES platform. Both features currently require
Win32 functions that don't exist in the WINAPI_FAMILY_GAMES subset.
Misc fixes:
- gtest-port.cc: Move GTEST_DISABLE_MSC_DEPRECATED_PUSH_ into
GTEST_HAS_STREAM_REDIRECTION conditional section where the corresponding
GTEST_DISABLE_MSC_DEPRECATED_POP_ is located.
- googletest-port-test.cc: Switch stream redirection tests to be conditional on
GTEST_HAS_STREAM_REDIRECTION instead of !defined(GTEST_OS_WINDOWS_MOBILE).
googletest avoids using the Abseil flag library, so googlemock should
do the same for consistency.

Google Test performs hidden test registration during process
startup. For test binaries that contain a large number of tests, this
registration can be costly. In this CL, we reduce the overhead of
registration via several tactics:
- Treat CodeLocation and FilePath as value types, using std::move to
pass them around.
- Reduce string copies in various places by either passing std::string
values via std::move, or passing const-refs to std::string instances.
- Use std::to_string to stringify an int in DefaultParamName rather than
a std::stringstream.
- Pull some std::string instances out of nested loops in
ParameterizedTestSuiteInfo::RegisterTests so as to reuse some
allocations, and replace stringstream with ordinary string appends.
- Use std::unordered_map in UnitTestImpl::GetTestSuite and
ParameterizedTestSuiteRegistry::GetTestSuitePatternHolder to spend a
little memory to turn O(N) lookups into constant time lookpus.
- Use range-based for loops in a few places.
- Use emplace-ish methods to add to containers where appropriate.
All together, these changes reduce the overall runtime of a series of 50
death tests in a single Chromium test executable by ~38% due to the
fact that the registration costs are paid in every death test's child
process.

Since Fuchsia engineers rarely work within this repo, initialize a lightweight fake @fuchsia_sdk repo rather than distributing the Fuchsia SDK here.

The Fuchsia team has been using either fork branches
(https://fuchsia.googlesource.com/third_
party/github.com/google/googletest/+/refs/heads/sandbox/fuchsia_bazel_sdk)
or patch files
(https://cs.opensource.google/fuchsia/fuchsia/+/main:build/bazel/patches/googletest/fuchsia-support.bundle)
to support googletest-based tests that run against a Fuchsia target device.
As our SDK is maturing and @platforms//os:fuchsia constraint has been added
for a while now, upstream Fuchsia gtest support to reduce technical debt and
overhead.
This change is noop for non-fuchsia platform builds.

Destruction in static teardown causes issues for Environments which own threads and try to join them in their destruction.
This may be a breaking change for users who call RUN_ALL_TESTS multiple times in the same main function if they also install environments, or those who access registered environments after RUN_ALL_TESTS.
The easiest fix is to only call RUN_ALL_TESTS once as the last line of the main function. Another potential fix is to re-register new instances of the Environment once before each call to RUN_ALL_TESTS.

Stack traces in assertion failures are an extremely useful tool for
developers tasked with investigating failing tests. It's difficult to
understate this. In contrast to ordinary test assertions (e.g.,
ASSERT_TRUE or EXPECT_FALSE), SUCCEED() is a developer-authored
directive that indicates a success codepath. In fact, the documentation
states that this directive doesn't generate any output. Generating stack
traces for uses of SUCCEED() is wasted work since they are never
printed. If this were to change one day in the future, they still would
not be useful since any emitted message would include the file and line
number where SUCCEED was used. In addition to being noise in the output
in this case, symbolization of stack traces is not free. In some
Chromium configurations, symbolization for use of SUCCEED() can incur a
cost in excess of 25 seconds for a test that otherwise takes 0-1ms; see
https://crbug.com/1517343.
In this CL, we suppress generation and emission of stack traces for
kSuccess messages to reduce the overhead of SUCCEED().

https://bazel.build/external/overview#bzlmod
Bzlmod will be the default in a future Bazel release.
By default it requires projects to be registered with the
Bazel Central Registry (https://registry.bazel.build/) and
thus uses regular releases by default.
Users that want to "live-at-head" can still do this through
with overrides (https://bazel.build/external/module#overrides).
This change updates GoogleTest dependencies to use released versions.
CI uses Bzlmod except in the case of linux_gcc-floor, which will
keep testing the old WORKSPACE-based dependency system.
