How to Automate your API test cases using Rest Assured
Posted By : Sana Khan | 12-Jan-2021
Rest-Assured is a JAVA library or a set of JAVA APIs that can be used for testing and validating RESTful web services. The REST-based services built on the peak of HTTP Builder are passed through this. From assisting the different REST requests to validating and verifying the responses from the different APIs you have used, Rest-Assured can do it all.
As compared to dynamic languages such as Ruby and Groovy, testing and validation in REST services using Java is more difficult. In other words, we can say it REST Assured brings the simplicity of using these languages into the Java domain. Hence you can simply create a test suite using JAVA.
Benefits of REST Assured:
1. REST Assured reduces the need for writing the same section of code many times.
2. Rest Assured supports for Behavior-Driven Development by using these test notation, Given, When, and Then, which makes the tests readable.
3.We can customize reports for the REST-assured.
How to Start:
To get started with REST Assured, we have to add it as a dependency to your project. If you're using Maven add the following entry in the pom.xml
<dependency>
<groupId>io.rest-assured</groupId>
<artifactId>rest-assured</artifactId>
<version>3.0.2</version>
<scope>test</scope>
</dependency>
Validate response data:
With REST Assured, you may not only verify response body contents, even also check the correctness of technical response data, such as the HTTP response status code, the response content type, and other response headers.
- The response status code is 200.
- The response content type equals "application/json."
- The value of the response header "Content-Length" equals to system generated.
First simple Rest Assured script:
Given().
param("a", "b").
header("c", "d").
when().
Method().
Then().
statusCode(aaa).
body("a, ”b", equalTo("c"));
