### Per-Test-Suite Setup and Tear-down Example

Source: https://github.com/ayugram/ayugram4a/blob/rewrite/TMessagesProj/jni/boringssl/third_party/googletest/docs/advanced.md

This C++ example demonstrates how to declare and define static members for shared resources, along with `SetUpTestSuite()` and `TearDownTestSuite()` methods within a test fixture class. Use this pattern when tests require expensive resources that can be safely shared.

```C++
class FooTest : public ::testing::Test {
 protected:
  // Per-test-suite set-up.
  // Called before the first test in this test suite.
  // Can be omitted if not needed.
  static void SetUpTestSuite() {
    shared_resource_ = new ...;
  }

  // Per-test-suite tear-down.
  // Called after the last test in this test suite.
  // Can be omitted if not needed.
  static void TearDownTestSuite() {
    delete shared_resource_;
    shared_resource_ = NULL;
  }

  // You can define per-test set-up logic as usual.
  virtual void SetUp() { ... }

  // You can define per-test tear-down logic as usual.
  virtual void TearDown() { ... }

  // Some expensive resource shared by all tests.
  static T* shared_resource_;
};

T* FooTest::shared_resource_ = NULL;

TEST_F(FooTest, Test1) {
  ... you can refer to shared_resource_ here ...
}

TEST_F(FooTest, Test2) {
  ... you can refer to shared_resource_ here ...
}
```

### GoogleTest Death Test Example: Killed by Signal

Source: https://github.com/ayugram/ayugram4a/blob/rewrite/TMessagesProj/jni/boringssl/third_party/googletest/docs/advanced.md

This example uses EXPECT_EXIT to verify that a statement terminates the process by a specific signal (SIGKILL). It also checks for a particular message on stderr.

```c++
TEST(MyDeathTest, KillMyself) {
  EXPECT_EXIT(KillMyself(), ::testing::KilledBySignal(SIGKILL),
              "Sending myself unblockable signal");
}
```

### Register Environment with a Global Variable

Source: https://github.com/ayugram/ayugram4a/blob/rewrite/TMessagesProj/jni/boringssl/third_party/googletest/docs/advanced.md

An example of registering a global test environment using a global variable. It's recommended to call `AddGlobalTestEnvironment()` explicitly in `main()` for better readability and to avoid initialization order issues.

### SizeSpecificPartitionAllocator Example

Source: https://github.com/ayugram/ayugram4a/blob/rewrite/TMessagesProj/jni/voip/webrtc/base/allocator/partition_allocator/PartitionAlloc.md

Satisfies allocations up to a maximum size (N - kAllocationGranularity). Contains buckets for all multiples of kAllocationGranularity up to the maximum. Allocations exceeding the maximum size will fail.

```c++
template <size_t N> class SizeSpecificPartitionAllocator
{
  // ...
};

const size_t kMaxAllocation = N - kAllocationGranularity;
// Allocations of size kMaxAllocation or less are satisfied.
// Allocations larger than kMaxAllocation will fail.
```

### GoogleTest Death Test Example: Compound Statement

Source: https://github.com/ayugram/ayugram4a/blob/rewrite/TMessagesProj/jni/boringssl/third_party/googletest/docs/advanced.md

This example demonstrates a death test using ASSERT_DEATH with a compound statement. It verifies that the statement causes a crash with a specific error message on stderr.

```c++
TEST(MyDeathTest, Foo) {
  // This death test uses a compound statement.
  ASSERT_DEATH({
    int n = 5;
    Foo(&n);
  }, "Error on line .* of Foo()" );
}
```

### ECC Public Key with Large Y-coordinate Signature (Example 2)

Source: https://github.com/ayugram/ayugram4a/blob/rewrite/TMessagesProj/jni/boringssl/third_party/wycheproof_testvectors/ecdsa_secp384r1_sha384_test.txt

Presents a message, its validity, and a signature for an ECC public key with a large y-coordinate. This example is similar to the previous one but with a different signature.

```text
msg = 4d657373616765
result = valid
sig = 306602310090b95a7d194b73498fba5afc95c1aea9be073162a9edc57c4d12f459f0a1730baf2f87d7d6624aea7b931ec53370fe47023100cbc1ef470e666010604c609384b872db7fa7b8a5a9f20fdefd656be2fcc75db53948102f7ab203ea1860a6a32af246a1

### Deriving Test Fixtures in googletest

Source: https://github.com/ayugram/ayugram4a/blob/rewrite/TMessagesProj/jni/boringssl/third_party/googletest/docs/faq.md

Test fixtures can be derived from a base fixture to share common setup and teardown logic. Ensure proper ordering of SetUp() and TearDown() calls between the base and derived fixtures.

```c++
// Defines a base test fixture.
class BaseTest : public ::testing::Test {
 protected:
  ...
};

// Derives a fixture FooTest from BaseTest.
class FooTest : public BaseTest {
 protected:
  void SetUp() override {
    BaseTest::SetUp();  // Sets up the base fixture first.
    ... additional set-up work ...
  }

  void TearDown() override {
    ... clean-up work for FooTest ...
    BaseTest::TearDown();  // Remember to tear down the base fixture
                           // after cleaning up FooTest!
  }

  ... functions and variables for FooTest ...
};

// Tests that use the fixture FooTest.
TEST_F(FooTest, Bar) { ... }
TEST_F(FooTest, Baz) { ... }
```

--------------------------------

### GoogleTest Death Test Example: Normal Exit

Source: https://github.com/ayugram/ayugram4a/blob/rewrite/TMessagesProj/jni/boringssl/third_party/googletest/docs/advanced.md

This example uses EXPECT_EXIT to verify that a statement exits normally with a specific exit code (0) and produces a given string on stderr. This is useful when the process is expected to terminate cleanly.

```c++
TEST(MyDeathTest, NormalExit) {
  EXPECT_EXIT(NormalExit(), ::testing::ExitedWithCode(0), "Success");
}
```

  player = new YT.Player("player", {
    "width": "100%%",

### C++ Example: Custom Mutually Prime Predicate-Formatter

Source: https://github.com/ayugram/ayugram4a/blob/rewrite/TMessagesProj/jni/boringssl/third_party/googletest/docs/advanced.md

Implements a custom predicate-formatter `AssertMutuallyPrime` to provide a detailed failure message for checking if two integers are mutually prime. This example demonstrates how to return `::testing::AssertionSuccess()` on success and `::testing::AssertionFailure()` with a custom message on failure.

```c++
// Returns the smallest prime common divisor of m and n,
// or 1 when m and n are mutually prime.
int SmallestPrimeCommonDivisor(int m, int n) { ... }

// A predicate-formatter for asserting that two integers are mutually prime.
::testing::AssertionResult AssertMutuallyPrime(const char* m_expr,
                                               const char* n_expr,
                                               int m,
                                               int n) {
  if (MutuallyPrime(m, n)) return ::testing::AssertionSuccess();

  return ::testing::AssertionFailure() << m_expr << " and " << n_expr
      << " (" << m << " and " << n << ") are not mutually prime, "
      << "as they have a common divisor " << SmallestPrimeCommonDivisor(m, n);
}
```

```bash
g++ -std=c++11 -isystem ${GTEST_DIR}/include -I${GTEST_DIR} \
    -pthread -c ${GTEST_DIR}/src/gtest-all.cc
ar -rv libgtest.a gtest-all.o
