I have an Electron application that needs to save some data when it’s closed by the user (e.g. just after the user clicked on the “Close” button). For this example, we want to store the resolution (width and height of the application in pixels) to a config file. The next time, the application starts, these values should be read and the application resized accordingly.

You will learn how to set up the test environment and run automated integration or E2E tests with Spectron, Mocha, and Chai. Furthermore, a short introduction to CSS selectors is given.
