Bread is made by mixing ingredients of more or less fixed proportions. There is a tolerance around these proportions defined by the quality standards. This level of tolerance ensures that the quality of the mix stays the same regardless of […]
Test Automation
One of the most powerful features of SinonJs is the ability to create a fake server. This feature is very useful when unit testing a component that’s connected to a server via an API. Fake servers let you write real […]
Fake Servers in SinonJs
Tests suites tend to grow together with applications. It is quite common that you need a significant amount of time to execute all your unit tests. Under these circumstances, you cannot afford to waste 5 secons on waiting for a […]
Fake Timers with SinonJs
This is part 5 of the automating testing series with Mocha, Chai and SinonJs. Part 1 and part 2 introduce the Mocha automated testing framework and the Chai assertion library. We then learned how to use SinonJs spies and stubs. […]
SinonJs Mocks
In part 1 and part 2 of this series, we learned the basics of using Mocha and Chai. Part 3 introduced SinonJs spies. We will continue with the exploration of an additional utility belt responsible for isolating the tested functionality […]
Stubbing with SinonJs
This series introduces automated testing libraries for Javascript applications with Mocha, Chai and SinonJs. The first part covers the fundamentals of Mocha and Chai. The second part describes how Mocha and Chai can test DOM manipulations and handle asynchronous tests. […]
SinonJs Spies
This is the second part on automated testing with Mocha, ChaiJs and SinonJs. If you have never used Mocha or ChaiJs before, I suggest reading the first part. We will continue where we left off last time. The syntax of […]
Asynchronous Tests and Fixtures with Mocha and ChaiJs
Many people claim that unit testing is a necessary condition for refactoring code. It is very hard to reliably refactor code without having good testing coverage. According to the definition of code refactoring, the process results in changes applied on […]
Writing Automated Tests with Mocha and Chai
The motivation behind introducing automated testing on client side can be twofold. Either inspiration or desperation. Suppose you are in a team thinking about the architecture of a new software solution. The task “from zero to hero” is often motivating […]
