expect() with no actual expectations

The Problem:

Recently, while reviewing our existing test codebase, I've noticed a dangerous kind of typo/mistake when expect() was used without the "matching" part:

expect(page.filters.fromDateLabel.getText(), "After");

I'm pretty sure toEqual() was meant to be used here:

expect(page.filters.fromDateLabel.getText()).toEqual("After");

The problem with this is that jasmine would not fail the expectation in this case (well, obviously because nothing was actually expected). And this gets us to a more serious problem - nothing was actually tested in a test case - it was passing with no expectations made. We were getting a false sense of what was tested.

The Question:

I want to catch these mistakes as fast as possible. How do you think I should handle the problem?

Thoughts:

• somehow fail a test case if there was no expectations made in it (not sure if jasmine has anything like this built-in)
• "patch" the expect() and issue a warning/raise an error if nothing was called on the "expect" part
• use static code analysis - define a custom eslint rule
