C++ assert Test

[pod...@gmail.com]

The program I have to test contains some C++ assert statement from
<cassert>.
I have something like that to test :

void Foo(int x, int y)
{
assert(x > y);
}

TEST(tassert, testAssert)
{
Foo(2, 1); //true
Foo(1, 2); //false
(...some ASSERT_*...)
}

When assert(false) is executed, not only the test crash, but all the
tests program crash.
How can I do to continue the execution of the test program with this
test marked as "failed" ?
I maybe forget something about deathtest or an execution flag or
something else..

{
Foo(2, 1);
EXPECT_DEATH(Foo(1, 2), "");
...
}

I don't know when it fail (I don't know the values of x and y) so if I
put EXPECT_DEATH and it don't fail, the test is marked as "fail". I
just want the test program not crash.
I think the assertion I need is "!EXPECT_DEATH".
(I don't have my code here, I hope I'm right..)

You can use EXPECT_EXIT(statement, ExitedWithCode(0), "") then.

Ok thanks, I'll try it.

But, is there any flag or something to lauch every test in its own thread?

(I use googletest to make large/fonctional tests not unit test, so I don't have control on everything. There are many "assert" in the code, so I can't put a death test on every statement)

No, we don't have such a flag. (BTW, I think you mean process instead
of thread.)

I'd say don't worry about it unless it's a real problem. It would be
nice if the assert doesn't crash the entire test program, but how
often does it happen? If it happens a lot, you probably have a bigger
problem to worry about.
