    Blog: Jest Preset Update October 2019

These are complete with example tests including testing the rendering of components, testing async functions using promises or callbacks and even simulating user events. You can learn more about the presets in the original post, Enable Jest testing of SharePoint Framework Projects in One Simple Step.

    Blog: Dealing with Undefined 'this' in React Event Handlers in a Performant Way

    Blog: Enable Jest testing of SharePoint Framework projects in one simple step

    Over the last two weeks, I have been presenting on the topic of the SharePoint Framework (SPFx) at a pair of SharePoint conferences (the European SharePoint Conference in Copenhagen & SharePoint Fest in Chicago).
