Setting Response Status​

JJ makes it easy to set the HTTP status code for your mock response. If you're testing a scenario where a resource is not found, you might want to return a 404 status code.

jj.Response(status=404)

By explicitly setting the status parameter, you can emulate various server responses, helping you to test edge cases in your application.

To customize the reason phrase, use the reason attribute:

jj.Response(status=404, reason="Custom Reason")

Crafting the Response Body​

JJ provides various options for setting the response body, ranging from simple text and JSON to binary data.

JSON Response​

To return a JSON response, utilize the json parameter. This will also automatically set the Content-Type header to application/json.

jj.Response(json={"message": "200 OK"})

Text Response​

To return plain text, utilize the text parameter.

jj.Response(text="200 OK")

Binary Response​

To simulate responses with binary data like images or files, use the body parameter with a bytes object.

jj.Response(body=b"<binary>")

Predefined Body​

JJ also lets you populate the response body using a file. This is particularly useful for loading predefined mock data.

jj.Response(body=open("responses/users.json", "rb"))

Setting Response Headers​

In addition to crafting the response body, JJ also allows you to set custom headers for your mock responses.

jj.Response(body="<p>text<p>", headers={"Content-Type": "text/html"})

In this example, the Content-Type header is explicitly set to text/html, indicating the type of the response content.
