gtest

svn checkout ....

configure
make
make install

默认装在 /usr/local/include /usr/local/lib 下
有两个库 libgtest 和 libgtest_main

使用时 gcc -I.. -L... -l...  .................

Once you are able to compile the Google Test library, you should create a project or build target for your test program. Make sure you have GTEST_ROOT/include in the header search path so that the compiler can find when compiling your test. Set up your test project to link with the Google Test library

test program -> test cases -> tests

ASSERT_*
EXPECT_*

<<

ASSERT_EQ(expected, actual);

the arguments' evaluation order is undefined (i.e. the compiler is free to choose any order) and your code should not depend on any particular argument evaluation order.

ASSERT_EQ() does pointer equality on pointers. If used on two C strings, it tests if they are in the same memory location, not if they have the same value. Therefore, if you want to compare C strings (e.g. const char*) by value, use ASSERT_STREQ() , which will be described later on. In particular, to assert that a C string is NULL, use ASSERT_STREQ(NULL, c_string) . However, to compare two string objects, you should use ASSERT_EQ.

TEST(test_case_name, test_name) {
 ... test body ...
}

fixtures:
class Footest : public ::testing::test

TEST_F(test_case_name, test_name) {
 ... test body ...
}


The ::testing::InitGoogleTest() function parses the command 
line for Google Test flags, and removes all recognized flags. This 
allows the user to control a test program's behavior via various flags, 
which we'll cover in .
 You must call this function before calling RUN_ALL_TESTS(), or
 the flags won't be properly initialized. 

int main(int argc, char **argv) {
  ::testing::InitGoogleTest(&argc, argv);
  return RUN_ALL_TESTS();
}

Fatal assertion	Nonfatal assertion	Verifies
ASSERT_THROW(statement, exception_type);	EXPECT_THROW(statement, exception_type);	statement throws an exception of the given type
ASSERT_ANY_THROW(statement);	EXPECT_ANY_THROW(statement);	statement throws an exception of any type
ASSERT_NO_THROW(statement);	EXPECT_NO_THROW(statement);	statement doesn't throw any exception
