cypress-runner-themes

Alternative themes for the Cypress Test Runner for Cypress v10+.

Currently supports dark-mode, light-mode and colorblind-mode.

Heavily inspired by cypress-dark and cypress-light-theme but all in one package.

Feel free to suggest/create additional themes. As the test runner changes over-time, the themes may break unexpectedly. For any issues please let us know. Thanks!

Themes

Dark

Light

Colorblind (Red/Green)

The three main types of color blindness are

• Deutan (red/green)
• Protan (red/green)
• Tritan (blue/green and yellow/red)

By replacing green with yellow, now the Cypress test results will show up as

• Yellow (passing)
• Red (failing)
• Blue (skipped)

This color combination addresses those with Deutan and Protan color-blindness. Those with sensitivity to red/yellow should keep the default Cypress test result colors.

If there is another case that isn't covered please let me know and I will add a theme for it.

Install

npm install --save-dev cypress-runner-themes

Use

To enable any of the themes, set the theme env var in your cypress.config.js file.

The acceptable theme values are dark, light, and colorblind.

"env": {
    "theme": "dark",
}

After, require the plugin in your support/e2e.js file

import "cypress-runner-themes";

Finally, the next time you run a test the theme will be applied.

Unfortunately, there's no hook to inject the theme into the test runner without running a test first. Hoping that changes in the future.

Development

For local development, install all dependencies (npm install) and change the getThemesFolder under src/utils to point toward the local css files.

const getThemesFolder = () => "src/themes"; // Enable for local development

Next, change the theme env var within the cypress.config.js to whatever you are testing.

Finally, run the cypress test runner npm run cy:open.

TODO

• [ ] Apply theme on runner load, not before a test begins
• [ ] Support cypress-plugin-api
• [ ] Remove "Colorblind" as explicit theme and allow toggle ability within runner
• [ ] Migrate over the fun Halloween mode from cypress-dark
