In this task, you are tasked with implementing the processRequest method within the HttpRequestProcessor class. You
are going to use a very simplified version of HttpClient with mocked logic.
If you are not familiar with the client-server architecture, feel free to check details about brief explanation of how HttpClient work:
Here’s a breakdown of how it typically works:
-
Sending a Request: When you want to access information from a server (like a webpage, data from a database, or other resources), the
HttpClientsends a request to the server. This request includes the URL (which specifies the address of the server and the specific page or data you want) and sometimes additional headers or data if needed. -
Receiving a Response: After the server receives and processes the request, it sends back a response to the
HttpClient. This response includes a status code (which tells if the request was successful or not), any data requested (like a webpage, image, or other data), and possibly some headers with extra information about the response. -
Handling the Response: The
HttpClientreceives this response and processes it according to the needs of the application. For example, it might display data on a webpage, store it in a database, or use it in some other way.
In essence, an HttpClient acts as a messenger, sending requests to and receiving responses from a server, enabling
your applications to interact with different web services seamlessly.
Your goal is to manage HTTP requests efficiently, ensure accurate logging of details, and handle responses using
Kotlin's also scope function. It's crucial to adhere to the specified logging format, as it will be checked by unit
tests.
Implement the processRequest method to accurately utilize the also function for logging side-effects while
processing HTTP responses effectively. Strict adherence to the specified logging formats is mandatory, as these are part
of the assessment criteria in the accompanying unit tests. This ensures functional correctness and compliance with
expected output formats for automated validation.
-
Method to Implement:
fun processRequest(url: String): ResponseData- This method accepts a URL string as its parameter and should return a
ResponseDataobject.
- This method accepts a URL string as its parameter and should return a
-
Using the
HttpClient:- Send an HTTP request to the provided URL using the
HttpClient'ssendRequest(url: String)method. - Capture the response in a variable.
- Send an HTTP request to the provided URL using the
-
Logging with
also:- Immediately after receiving the response, use the
alsoblock to log:- "Response Status:
<STATUS_CODE> - <STATUS_TEXT>" - "Response Content:
<CONTENT>"
- "Response Status:
- These logs are crucial for passing unit tests that verify the correctness of the implementation based on the expected output format.
- Immediately after receiving the response, use the
-
Response Handling:
- If the
statusCodein the response is 200:- Use the
alsoblock again to log:- "Processing content:
<CONTENT>"
- "Processing content:
- Return a
ResponseDataobject with "Success" as the status and the actual content of the response.
- Use the
- If the
statusCodeis not 200:- Return a
ResponseDataobject with "Failure" as the status and a message indicating the failure along with the status code:- "Request failed with status:
<STATUS_CODE>"
- "Request failed with status:
- Return a

The provided classes in the task serve specific purposes related to making and handling HTTP requests and responses. Check details below if you need more information about them.
-
HttpClientInterface:- Purpose: This interface defines the structure for an HTTP client class. It has one
method,
sendRequest(url: String): HttpResponse, which is intended to send an HTTP request to the specified URL and return an HTTP response. - Functionality: It acts as a contract for any class that implements it, ensuring they provide a specific
implementation of the
sendRequestmethod.
- Purpose: This interface defines the structure for an HTTP client class. It has one
method,
-
SimpleHttpClientClass:- Purpose: This class is an implementation of the
HttpClientinterface. It simulates the behavior of an HTTP client by providing a mock implementation of thesendRequestmethod. - Functionality: When the
sendRequestmethod is called, it prints a message indicating the URL to which a request is being sent and returns a simulatedHttpResponseobject with hardcoded values (status code 200, status text "Success", and a generic response content). This is useful for testing without needing to connect to an actual external server.
- Purpose: This class is an implementation of the
-
HttpResponseData Class:- Purpose: This data class represents the structure of an HTTP response.
- Functionality: It holds three properties:
statusCode(the HTTP status code of the response),statusText(a textual description of the status code), andcontent(the body of the response, which could be the data retrieved from a server). This class allows easy access and manipulation of these properties in the client code.
-
ResponseDataData Class:- Purpose: This class is used to format the final output of processing an HTTP request.
- Functionality: It contains two properties:
status, which indicates the outcome of the request (like " Success" or "Failure"), andcontentSummary, which provides a summary or the actual content of the response. This class is useful for encapsulating the result of an HTTP request in a structured form that is easy to log or display.
