Discover how to manipulate the Node.js require cache using libraries like mockery, proxyquire, and rewrite, and then compare the differences between the modules.
- [Instructor] All the test doubles in the world…won't do any good if we can't actually use them.…In node.js and in most languages,…units of code usually have dependencies.…That's a good thing,…because it promotes reusability and modularity.…As an example, our application has dependencies…on the sequel-like database…and the debugger module for logging.…Of course, you can actually write tests…that use other components, but testing dependencies…isn't actually unit testing.…It's integration testing.…
