If I have something like:
ASSERT_TRUE(RANGE(val1, val2, abs_err) || RANGE(val1, val3, abs_err));
How would I use ASSERT_NEAR instead of ASSERT_TRUE?
I've attempted to break up the statement into two ASSERT_NEAR statements, like below, but the test fails.
ASSERT_NEAR(val1, val2, abs_err);
ASSERT_NEAR(val1, val3, abs_err);
Your use case is: any of these two condition should be true.
So use ::testing::AnyOf(m1,m2,...)!
Equivalent of ASSERT_NEAR(lhs,rhs,max_error) in matchers world is ::testing::DoubleNear(rhs,max_error) - so your example will look like this:
ASSERT_THAT(val1, AnyOf(DoubleNear(val2, abs_err),
DoubleNear(val3, abs_err)));
If you need both of your conditions are true - use ::testing::AllOf - actually your attempt is just equivalent of AllOf - that is why it failed.
