reject-requires-await
Assert.rejects must be preceded by an await, otherwise the assertion
may not be completed before the test finishes, might not be caught
and might cause intermittent issues in other tests.
Examples of incorrect code for this rule
Assert.rejects(myfunc(), /startup failed/, "Should reject");
Examples of correct code for this rule
await Assert.rejects(myfunc(), /startup failed/, "Should reject");
