toBeLessThan(expectedValue) is a comparison function that evaluates to true or false. It must be called in the chain after the t.expect(value) or .and(value).
toBeLessThan is equivalent to received < expected
When toBeLessThan(expectedValue) evaluates to false, the chain is broken, and the test is marked as failed. When the chain is broken, further checks inside of the test are omitted.
|expectedValue||any||The expected value|
