In this post, I’ll add unit tests to the example application that I’ve been fiddling around with in the recent posts.
In the previous post, we explored the Page Object pattern and rewrote our tests to use this technique. Sometimes, it can be that the tests appear to be a bit verbose due to the usage of promises. Additionally, promises and asynchronous programming in general can be somewhat confusing to developers. Let’s see some ways of making the tests shorter and easier to read.
In the previous post, we wrote some functional tests and we encountered our first failing test. Let’s see how we can go about investigating these failures, both on a developer machine and during continuous integration. Continue reading Functional Testing – Dealing with failed tests
Before we go any further, let’s take a break and add a bit of a structure to our functional tests. This will allow us to reduce the code we have to write for each test. We’ll also start thinking about how to organize the tests into folders and files. Continue reading Functional Testing – First steps towards a framework
Let’s continue our functional testing examples by adding a few more tests. This will demonstrate why we need to start thinking about the structure of our tests and why we should be developing a framework that will allow us to write less code.

Let’s have a look at a first example of writing and running a functional test. This is going to be a very basic hello world example, but still it gives an opportunity of looking at the bare minimum usage of WebDriverIO and a first taste of asynchronous programming with promises. Continue reading Functional Testing Hello World
In the previous post we had a look at sinon spies. With spies, we are able to determine if a specific function was called or not. Usually the dependencies between units are more interesting, they involve units co-operating, exchanging data and so on. Spies do not suffice. Let’s have a look at another technique, using stubs.
