Unit-testing Redux
We have already fiddled with the Jest testing framework in Chapter 4, Chat System with Electron and React: Enhancement, Testing, and Delivery (Writing Unit-tests section). Redux introduces new concepts, such as actions and reducers. Now, we are going to unit-test them.
As you may remember, to run Jest, we need to configure Babel:
.babelrc
{ "presets": [ ["env", { "targets": { "node": 7 }, "useBuiltIns": true }], "react", "stage-3" ], "plugins": [ "transform-class-properties", "transform-decorators-legacy" ] }
Again, with env preset, we target Babel on Node.js 7 and enable the extra plugins we used in the webpack configuration.
