This tests whether the first parameter is not equal to the second parameter. If both parameters are numbers, the values are instead compared using {{code|assertNotWithinDelta}} with delta 1e-8 (0.00000001) since numbers are represented as [[floating point]]s with limited precision.

</syntaxhighlight>
=== assertNotWithinDelta ===
<syntaxhighlight lang="lua">
self:assertNotWithinDelta(expected, actual, delta, message)
</syntaxhighlight>
For two numbers, this tests whether the first is not within a given distance (delta) from the second. This test is the inverse of [[#assertWithinDelta|assertWithinDelta]].

self:assertNotWithinDelta(0.1, calculator.subtract(0.3, 0.1), 1e-10)
