Understanding & Debugging Network Requests
I work on web applications for a living. I meander across the stack, but my experience tends towards front-end engineering. Legitimately nothing I do would be possible without HTTP requests.
The Network Layer
I’m going to start by briefly covering some computer science concepts. Full disclosure — my understanding of these ideas is basic. I don’t have a degree in computer science, and I’m not a network engineer. If you fall into one of those categories and have strong feelings about this post, please reach out! I would love to learn more.
Debugging in the Browser
Let’s start by focusing on that first request — the one between the browser and our application. We can inspect and debug these requests using existing developer tools in your browser of choice.
Debugging in an Application
We can also take a look at the other side of the first request on our chart, and look at our application to see how it handles incoming requests with routing and middleware.
Debugging in a Sandbox
Now let’s take a look at the requests that our application sends out. Let’s say our application has received a request from the browser, but in order to respond with the correct page, it needs to fetch some information from the server.
Debugging Database Requests
We only have one more request on our chart — the one connecting an API to a Database. There is a whole world of options when it comes to getting information from your database. You could use one (or more!) of the following:
What is a network request?

Which library handles network requests?

What is the request list of the Network Monitor?

Clicking an item in the search results highlights that item in the monitor list, and displays the corresponding information in the request details pane.

Testing Strategies
- Cypress helps you test the entire lifecycle of HTTP requests within yourapplication. Cypress provides you access to the objects with information aboutthe request, enabling you to make assertions about its properties. Additionallyyou can even stub and mock a request's response. C…
Stubbing
- Cypress enables you to stub a response and control the body, status,headers, or even delay. cy.intercept()is used to control the behavior ofHTTP requests. You can statically define the body, HTTP status code, headers,and other response characteristics.
Routing
- When you use cy.intercept()to define a route,Cypress displays this under "Routes" in the Command Log. When a new test runs, Cypress will restore the default behavior and remove allroutes and stubs. For a complete reference of the API and options, refer to thedocumentation for cy.intercept().
Waiting
- Whether or not you choose to stub responses, Cypress enables you todeclaratively cy.wait()for requests and theirresponses. Here is an example of aliasing requests and then subsequently waiting on them: If you would like to check the response data of each response of an aliasedroute, you can use several cy.wait()calls. Waiting on an aliased route has big advantages: 1. Tests are …
Command Log
- Cypress logs all XMLHttpRequests and fetches made by the application undertest in the Command Log. Here is an example of what this looks like: The circular indicator on the left side indicates if the request went to thedestination server or not. If the circle is solid, the request went to thedestination server; if it is outlined, the response was stubbed bycy.intercept() or cy.route()a…
