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 implemented a new feature for our calculator: it makes a bell sound when you divide by zero. The bell is a simple function that the calculator calls and it is provided as a constructor dependency. We wrote a unit test for this as well, but the code for that is a bit verbose. Let’s see how we can use a mocking library like sinon to reduce and standardize the testing code. Continue reading “Using sinon spies”
In the previous post we started writing a basic Calculator class and added the first unit test. Let’s have a closer look at that unit test and extend our calculator with more features.
Here’s a small tip that puzzled us at work the other day for a while. How do you use chai-as-promised together with chai-string? Continue reading “Chai as promised with Chai string”
