HTTP Requests & Responses

Books URL: https://apis.ccbp.in/book-store

Example:

https://apis.ccbp.in/book-store?title=IndiaQuery ParameterValuetitleValue of the searchInput element. Example: India

Method: GET

It should pass test conditions:

When a value is provided in the HTML input element with id searchInput and Enter Key is pressed, an HTTP GET request should be made to the Books URL with the query parameter 'title' as the value of the searchInput element

When the HTTP GET request is successful, then the searchResults element should consist of HTML image elements with src attribute value as the value of key 'imageLink' and HTML paragraph elements with text content as the value of key 'author' from HTTP response
