Snapshotted from 5e7fd50e17b6edf1cadff973d0ec68966cf3265e in the upstream repository: https://github.com/google/googletest Since standalone builds and bots will need this, checking in a copy rather than require everyone use gclient, repo, git submodules or scary CMake scripts is probably simplest. Consumers with their own copies of googletest will likely wish to ignore or even exclude this directory.

|
|
// class. You don't have to do that exactly, but it helps to keep
|
|
// your tests organized. You may also throw in additional tests as

// If we write NULL instead of

//
|

// static_cast<const char *>(NULL)
|
|
//
|
|
// in this assertion, it will generate a warning on gcc 3.4. The
|
|
// reason is that EXPECT_EQ needs to know the types of its
|
|
// arguments in order to print them when it fails. Since NULL is
|
|
// #defined as 0, the compiler will use the formatter function for
|
|
// int to print it. However, gcc thinks that NULL should be used as
|
|
// a pointer, not an int, and therefore complains.
|
|
//
|
|
// The root of the problem is C++'s lack of distinction between the
|
|
// integer number 0 and the null pointer constant. Unfortunately,
|
|
// we have to live with this fact.
