 The `@testcafe-community/axe` module allows you to define the `context` and `options` [axe.run parameters](https://github.com/dequelabs/axe-core/blob/develop/doc/API.md#api-name-axerun) in a TestCafe test.
 
 ```js
-test('Automated accessibility testing', async () => {
+test('Automated accessibility testing', async (t) => {
     const context = { exclude: [['select']] };
     const options = { rules: { 'html-has-lang': { enabled: false } } };

-## Additional features
-
-By default `checkForViolations` does not allow any violations, but if you want more fine grained control 
-there are a couple options.  First, you can pass in `numAllowed` which will only fail the test if the 
-number of violations exceeds that number.  Secondly, `checkViolations` returns the list of violations from
-axe-core so you can inspect it if needed.
-
-```js
-test('Automated accessibility testing', async () => {
-    const {violations} = await checkForViolations({numAllowed:2});
-
-    // do stuff with violations.
+    await checkForViolations(t, context, options);
