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.
