|

|
| -// 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)

|

|

|

|
| -// 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");
