The Terra service integrates [axe accessibility](https://github.com/dequelabs/axe-core) and screenshot comparison testing commands into the test environment. Invoking the axe engine will perform a static analysis of the entire document and dom structure.
A list of available commands can be viewed [here](../about
An optional selector can be configured in the `serviceOptions` to specify the default element to be captured when taking a screenshot. Accessibility testing ignores this option and always tests the entire document.
Type: `string`
Required: `false`
Default: `[data-terra-test-content] *:first-child`
Example:
```js
// wdio.conf.js
const { config } = require('@cerner/terra-functional-testing');
config.serviceOptions = {
selector: '#root',
};
exports.config = config;
```
