How to use Cypress Intercept to Stub API Responses
Cypress provides a complete package for End to End automation, it can help you with UI automation, API automation and web application automation. Cypress is a Unique tool it makes all the tasks associated with test automation very easy and doable, In addition to that it can provide you a functionality called Intercept which helps in mocking or stubbing the request and its associated response.

Why use Cypress Intercept
There are various reasons why we are using Cypress Intercept, the most
important reason is the ease of its usage for performing Mocking and
stubbing. We can easily take control of requests and responses which are
performing communication between application and API or services and
make required changes in that. We can even take a record for all these
transactions and use these responses in the absence of an API backend.
We can use Cy.intercept for manipulating network requests which were
made by application during testing, we can intercept specific HTTPS
requests, determine its properties and then decide how we are going to
respond to the same.
With the help of Cypress intercept we can perform performance testing,
security testing and reduce the risk of test flakiness, reduce the number of
false failures and perform testing of edge cases.
What is Mocking?
Mocking or Stubbing are the process of providing predefined responses to
specific requests. We use this technique when we want to remove our
dependency from all the third party services, there are cases when these
third party API services are not stable enough and we are not getting
desired support. So for resolving this issue we create responses for the
required request and make sure whenever automation hits the backend
with a request which involves third party dependency, it will get the already
defined response.
How can we use Cypress Intercepts for Security
and performance testing?
Using Cypress Intercepts we can explore different dimensions and scope of
testing.
