An assertion documents the expected state of specific program variables at the point where the assertion is written, in a testable way so that we can find program bugs — logic errors that have led to corrupted program state. Assertions are only about finding bugs, not doing program work.

But we need to be smart about it.

The first and most obvious is that they are long on how to start, but short on how to finish.

It’s also awkward, an exercise of the blindfolded people describing the pachyderm.
