Macro verify_ne 

macro_rules! verify_ne {
    ($actual:expr, $expected:expr $(,)?) => { ... };
}

Checks whether the second argument is not equal to the first argument.

Evaluates to Result::Ok(()) if they are not equal and Result::Err(TestAssertionFailure) if they are equal. The caller must then decide how to handle the Err variant. It has a few options:

• Abort the current function with the ? operator. This requires that the function return a suitable Result.
• Log the test failure and continue by calling the method and_log_failure.

Of course, one can also use all other standard methods on Result.

Invoking this macro by itself does not cause a test failure to be recorded or output. The resulting Result must be handled as described above to cause the test to be recorded as a failure.

Example:

use googletest::prelude::*;

#[test]
fn should_fail() -> Result<()> {
    verify_ne!(1, 1)
}
