J.B. Rainsberger sums it up:

Fundamentally, Behaviour-driven development is Test-driven development
practiced correctly, though frameworks tend to have different naming
conventions.

As JB points out, the wording is key --- some people associate specific
meanings with the word "test", which aren't what TDD is about, and using
"behaviour specification" instead gets around that.

I have experimented with various syntaxes in C++, such as

CHECK(some_value, must_be > 2 and must_be < 42);
CHECK(some_container, must_contain(3));

In the end, I've always come back to our trusty friend: ASSERT.

ASSERT_GREATER_THAN(some_value,2);
ASSERT_LESS_THAN(some_value,42);
ASSERT_NOT_EQUALS(std::count(some_container.begin(),some_container.end(),3),0);
