Visual Reporter

Background

The @wdio/visual-service has a reporting output since v5.2.0 which will output the diffs into a large JSON file. This project is a sample of what people could do with the output.

To make use of this utility, you need to have the 'output.json' file generated by the Visual Testing service. This file is only generated when you have the following in your configuration:

export const config = {
    // ...
    services: [
        [
            // Also installed as a dependency
            "visual",
            {
                createJsonReportFiles: true,
            },
        ],
    ],
    },
}

For more information, please refer to the WebdriverIO Visual Testing documentation.

Installation

The easiest way is to keep @wdio/visual-reporter as a dev-dependency in your package.json, via:
