Testing React Components Using Shallow Rendering

Previously we tested React components with Jasmine and jQuery, but what if we want to test without having a DOM available? React's testing tools have you covered with Shallow Rendering. Shallow Rendering will render the object as it would before sending it to be painted on the screen. This makes the final state of a component available for testing.


Testing React Components With Jasmine

Making a React component feels straight forward. Testing a React component should feel just as straight forward. Now that I have built tests for my React code, I can say it is.


Making Your First React Component Raise Events and Update (update to v0.14.x)

My last article described creating a simple React component. This post will walk through adding a click event to that component. The click event will modify the data the component is displaying. React will automatically update the screen without us making any explicit requests based on the change in data.


Making Your First React Component (updated to v0.14.x)

Update: Fixed example with 0.14.x ReactDom format and to use states, not props.

In a world of Angulars and Embers, what is the point of a library that only provides a third of the MVC equation? React offers simplicity and a welcome decoupling of display and business logic.


Tweak the Angular Test By Controlling the Template

We recently finished bringing our test coverage up to 90%+ on our Angular project. The team worked hard and I am proud of our accomplishments. Going forward we are using TDD and this has proven to be an interesting experience that has provided new challenges. We have found building Angular directives through test driven development to be a little challenging since the templates haven't been built yet. We aren't going to know what to build right away, and we are loathe to break our rhythm and constantly be updating a template file. A bigger problem is the template creating an external dependency which is never a good thing for unit tests. When it comes time to do e2e testing and using Selenium or Protractor then the whole template needs to be run. If I'm starting with unit tests to define my code, how can I use a template without these problems? We found one method that we like - the $templateCache.
