How to use Cypress Intercept to StubAPI ResponsesCypress is a Unique tool it makes all the tasks associated with testautomation very easy and doable, In addition to that it can provide you afunctionality called Intercept which helps in mocking or stubbing the requestand its associated response. Using which user can active test automationand its running ability can be assured even if api services are down.What is Intercept ?Intercept is a fairly new concept in the world of service virtualization, the“cy.intercept()” is a very powerful concept, using this we can monitor all theinteraction of the application with the webservices or third party API. Duringtest automation and execution it becomes extra useful as we can controlvarious aspects of applications and its interaction with external API andservices.
Why use Cypress InterceptThere are various reasons why we are using Cypress Intercept, the mostimportant reason is the ease of its usage for performing Mocking andstubbing. We can easily take control of requests and responses which areperforming communication between application and API or services andmake required changes in that. We can even take a record for all thesetransactions and use these responses in the absence of an API backend.We can use Cy.intercept for manipulating network requests which weremade by application during testing, we can intercept specific HTTPSrequests, determine its properties and then decide how we are going torespond 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 offalse failures and perform testing of edge cases.What is Mocking?Mocking or Stubbing are the process of providing predefined responses tospecific requests. We use this technique when we want to remove ourdependency from all the third party services, there are cases when thesethird party API services are not stable enough and we are not gettingdesired support. So for resolving this issue we create responses for therequired request and make sure whenever automation hits the backendwith a request which involves third party dependency, it will get the alreadydefined response.How can we use Cypress Intercepts for Securityand performance testing?Using Cypress Intercepts we can explore different dimensions and scope oftesting.
