Automating GET and DELETE Request Using Rest Assured Testing

In the previous blog, we already have understood the basic terminology that we will be using during rest assured testing. We also have seen that how to setup Rest Assured JAR or maven dependency in our project.

In this blog, we will try to automate two very simple basic API (GET and Delete) to get some hands-on experience.

For this purpose, I would be using https://reqres.in/ which provides a few sample API for testing.

Please note in order to use Rest Assured effectively we need to do some static import manually in our eclipse IDE.

import static io.restassured.RestAssured.given;

import static org.hamcrest.Matchers.equalTo;

Let’s first start with One Simple Get Request on https://reqres.in/

As shown in the below screenshot once we fire the Get Request to Server. The server will respond back with status Code 200 which means the response is a success along with body.

In this case, our Base URI is: https://reqres.in/

and successive URI for passing Get request is "/api/users?page=2".

Before Moving Further to Coding part let's fire the same request in Postman and see the response.

As we can see in the above screenshot we are getting the same response along with some additional details in the form of Cookies and headers which will ultimately help us to validate different scenarios while doing API Testing.

Below is the first test for getting the list of the user. As you might observe in the below code we have written all the code in BDD Format using Given, When, Then and extract the response in the form of String.

Now you might be wondering it out how I have asserted i.e validated different values from the server which I am not getting while seeing the response

For that purpose Postman Will help us a lot.

As shown in the above screenshot for validating the Header response we need to use the header in the code and similarly need to use body for validating any specific response from JSON Body.

Below is the output for Code execution.
