Delivery pipelines and source code management systems help—for example, you can gate pull requests on a failing test. One way to increase the confidence you get from your tests is to have more of them. By improving your system under tests in a way that invites more testing, your testing becomes easier in different ways.

In JavaScript, you can get around this with an immutability library; for example, Immutable.js , Lodash , or Ramda. For example, say that the return type of a function should be a prime number.
