Automate Testing of Rest API using Rest Assured

JSON Schema is a powerful tool for validating the structure of JSON data or your JSON Response. JSON Schema itself is written in JSON. It is data itself, not a computer program. It’s just a declarative format for “describing the structure of other data”.  The JSON document being validated or described we call the   instance , and the document containing the description is called the   schema . JSON Schema validation is done to check whether the response received is correct or is structured according to the defined schema for your project.  Let's loo k at an example of JSON Schema validation using Rest Assured. Here we are making use of Google Search API that we studied in  Testing GET Requests and their Responses using Rest Assured . I would highly recommend reading previous posts before reading this one. Lets us create a JSON File where we will define the JSON Schema for our response ( JSON Schema of a Response that we will get when...

  In one of the earlier post, we studied about Extracting a JSON Response with RestAssured ,  before following this tutorial, I would recommend reading the previous blogs.  I would assume that everyone following this tutorial has knowledge of Java and TestNG. If you need help then please follow tutorials on   Java   and   TestNG . In this post, we will learn about comparing JSON Responses using JSONAssert . Once the response is extracted we will store it into Response class and later verify the entire response using a single assert statement instead of comparing specific attributes. The disadvantage of directly comparing the response as string without JSONAssert is as follows: If we compare two jsons by simply comparing the json string then it fails to let us know where exactly the comparison has failed. It will also mark json as failed if the order of array elements in json is different.  However if use JSONAssert Library, it will  let us know th...

In the previous post, we studied about f inding broken links using Rest Assured . In this post, we will learn about verifying file download using Rest Assured. We will first download the file for which we will perform the verification of size. We will download  rest-assured-3.0.5-dist.zip   file   from Rest Assured Download   Section . We will save the file inside our eclipse project.  Now let us look at an example of verifying file download using Rest Assured: import org.testng.Assert ; import org.testng.annotations.Test ; import java.io.File ; import static io . restassured . RestAssured .*; public class GetRequestTest { @Test public void verifyFileDownload () { int fileSize ; File filePath = new File ( System . getProperty ( "user.dir" )+ "/resources/rest-assured-3.0.5-dist.zip" ); fileSize = ( int ) filePath . length (); System . out . println ( "The actual value is " + f...
