-/**
- * This API is used for the Web API testing. You can use it to trigger API endpoints, configure micro-services, prepare

- * <p> Each Playwright browser context has associated with it {@code APIRequestContext} instance which shares cookie storage with the
- * browser context and can be accessed via {@link BrowserContext#request BrowserContext.request()} or {@link Page#request

- * <p> **Cookie management**
- *
- * <p> {@code APIRequestContext} retuned by {@link BrowserContext#request BrowserContext.request()} and {@link Page#request
- * Page.request()} shares cookie storage with the corresponding {@code BrowserContext}. Each API request will have {@code Cookie}
- * header populated with the values from the browser context. If the API response contains {@code Set-Cookie} header it will
- * automatically update {@code BrowserContext} cookies and requests made from the page will pick them up. This means that if you
- * log in using this API, your e2e test will be logged in and vice versa.
- *
- * <p> If you want API requests to not interfere with the browser cookies you shoud create a new {@code APIRequestContext} by calling
- * {@link APIRequest#newContext APIRequest.newContext()}. Such {@code APIRequestContext} object will have its own isolated cookie
