Reliability is paramount to good testing, and there are steps you can take to optimize pass or fail executions. In this Node.js tutorial, you will learn how to install Nock to help speed up the process of testing by simulating a server connection to test that an application is working.

- There are some steps that we can take to…make these tests run a little bit faster…and also make them more reliable…so that they will actually pass or fail based off of…whether these functions are working or not.…Take a look at Load Abraham Lincoln's wikipedia page.…That's taken 230 milliseconds to work…because we are actually loading…Abraham Lincoln's Wikipedia page.…This test is dependent upon us having a…web connection working.…It's also dependent on Wikipedia being up and running.…When we run this test, we are actually hitting…Abraham Lincoln's page on Wikipedia.…
When we test our "loadWiki" function,…we require Wikipedia.…The "loadWiki" function is actually hitting Wikipedia.…That's how we want this function to work in production,…but when we're testing it, this seems a little…unnecessary and a little bit time consuming.…The solution is to create a Mock Wikipedia,…so that when we actually run this test,…we don't have to hit Wikipedia, but our…"loadWiki" function can interact with our Mock…as if it were Wikipedia.…
Alex Banks shows how to install Node.js on a Mac or PC and work with the Node.js core: the global object, event loop, http module, and file system. Then he covers reading and writing data, streaming data, making http requests, and working with the node package manager (npm). In the final chapters, he shows how to start sessions on web servers, communicate with web servers and clients with WebSockets, use the Express framework to develop applications, and test and debug Node.js code. Want to speed up your Node.js workflow? Check out the tutorials on automating tasks with Grunt and npm scripts.
