In the root level of your testing folder, install the @axe-core/watcher package and all of its dependencies using npm or your preferred package manager (for example, Yarn or pnpm).

npm install --save-dev @axe-core/watcher

In your test files, import the wdioConfig(), the wrapWdio() function, and the WdioController class from @axe-core/watcher:

const {
  wdioConfig,
  wrapWdio,
  WdioController
} = require('@axe-core/watcher')

In your test setup code (typically in a before or beforeAll block), wrap any existing code for creating a browser instance with a call to wdioConfig(), while providing your API key:

const browser = await wdio.remote(
  wdioConfig({
    axe: {
      apiKey: process.env.API_KEY
    }
  })
)

Once you have a browser instance, create an instance of the WdioController class:

const controller = new WdioController(browser)

Wrap your browser instance with the wrapWdio() function, providing the browser instance and the controller instance:

wrapWdio(browser, controller)

Finally, ensure all test results from axe Watcher are flushed out. To do this, add the following block of code to your test teardown code (typically in an afterEach block):

afterEach(async () => {
  await controller.flush()
})
