- |
-// 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) \ |

- |
-// 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 ExitedWithCode { |
- public: |
- explicit ExitedWithCode(int exit_code); |
- bool operator()(int exit_status) const; |
- private: |
- const int exit_code_; |
-}; |
- |
-// Tests that an exit code describes an exit due to termination by a |
-// given signal. |
-class KilledBySignal { |
- public: |
- explicit KilledBySignal(int signum); |
- bool operator()(int exit_status) const; |
- private: |
- const int signum_; |
-}; |
- |
-// 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; |
-// } |
-// LOG(DFATAL) << "death"; |
-// return 12; |
-// } |
-// |
-// TEST(TestCase, TestDieOr12WorksInDgbAndOpt) { |
-// int sideeffect = 0; |
-// // Only asserts in dbg. |
-// EXPECT_DEBUG_DEATH(DieInDebugOr12(&sideeffect), "death"); |
-// |
-// #ifdef NDEBUG |
-// // opt-mode has sideeffect visible. |
-// EXPECT_EQ(12, sideeffect); |
-// #else |
-// // dbg-mode no visible sideeffect. |
-// EXPECT_EQ(0, sideeffect); |
-// #endif |
-// } |
-// |
-// This will assert that DieInDebugReturn12InOpt() crashes in debug |
-// mode, usually due to a DCHECK or LOG(DFATAL), but returns the |
-// appropriate fallback value (12 in this case) in opt mode. If you |
-// need to test that a function has appropriate side-effects in opt |
-// mode, include assertions against the side-effects. A general |
-// pattern for this is: |
-// |
-// EXPECT_DEBUG_DEATH({ |
-// // Side-effects here will have an effect after this statement in |
-// // opt mode, but none in debug mode. |
-// EXPECT_EQ(12, DieInDebugOr12(&sideeffect)); |
-// }, "death"); |
