RestAssured - Class library

  • Popular and Widely used java library for RestAPI Automation
  • We can utilize the advantages of Java or Groovy
  • Doesn’t have any limitations and can be combined with different frameworks.
  • Easy integration with existing framework and customization
  • Library provides an option of :
    • writing any tests
    • performing any manipulations with data during the testing process leaving tests independent
Advantages:
  • Opportunity to apply ready-made tools without connecting additional libraries.
  • Comprehensive documentation is available on Github.
  • Extensive testing options in combination with different frameworks for testing and reports building.
  • Tests writing in the form of code using Java or Groovy with an option to update, improve the code’s quality or the number of tests.
  • Independence from the platform or development environment.
Disadvantages:
  • The necessity of having a basic knowledge of Java, Groovy, Maven and the experience of working with dependencies, command line and IDE.
  • Code quality and time necessary for compilation directly impact test running speed.
  • No GUI as for Postman and Katalon Studio.
  • A tester has to connect and set up additional tools for reports building.
  • It will take some time to check general API working efficiency and spend time on test writing.
Language Support:
  • Java or Groovy
Library Combinations-1:
  • RestAssured
  • TestNG
  • GSON
  • Log4j
Library Combinations-2:
  • RestAssured
  • Junit
  • GSON
  • Log4j
GET Request

POST Request
public class SampleAPITest { @Test public void PostEmpDetails() { RestAssured.baseURI = "http://192.168.20.150:3000"; RequestSpecification request = RestAssured.given(); request.header("Content-Type", "application/json"); JSONObject requestParams = new JSONObject(); requestParams.put("name", "Rajendra"); requestParams.put("salary", "20000") request.body(requestParams.toJSONString()); Response response = request.post("/employees"); String responseBody = response.getBody().asString(); System.out.println("Response Body is => " + responseBody); int statusCode = response.getStatusCode(); Assert.assertEquals(statusCode, "201"); String successCode = response.jsonPath().get("SuccessCode"); Assert.assertEquals( "Correct Success code was returned", successCode, "OPERATION_SUCCESS"); } }
PUT Request
public class SampleAPITest { @Test public void PutEmpDetails() { int empid=122; RestAssured.baseURI = "http://192.168.20.150:3000"; RequestSpecification request = RestAssured.given(); request.header("Content-Type", "application/json"); JSONObject requestParams = new JSONObject(); requestParams.put("name", "Rajendra"); requestParams.put("salary", "21000") request.body(requestParams.toJSONString()); Response response = request.put("/employees/"+ empid); int statusCode = response.getStatusCode(); System.out.println(response.asString()); Assert.assertEquals(statusCode, 200); } }
DELETE Request
public class SampleAPITest { @Test public void DeleteEmpDetails() { int empid=122; RestAssured.baseURI = "http://192.168.20.150:3000"; RequestSpecification request = RestAssured.given(); request.header("Content-Type", "application/json"); Response response = request.delete("/employees/"+ empid); int statusCode = response.getStatusCode(); System.out.println(response.asString()); Assert.assertEquals(statusCode, 200); String jsonString =response.asString(); Assert.assertEquals(jsonString.contains("successfully! deleted Records"), true); } }

Request with Query params

public class SampleAPITest { @Test public void GetEmpDetails() { RestAssured.baseURI = "http://192.168.20.150:3000"; RequestSpecification request = RestAssured.given(); request.param("name", "rajendra").param("age", "15"); request.header("Content-Type", "application/json"); Response response = request.get("/employees/1"); String responseBody = response.getBody().asString(); System.out.println("Response Body is => " + responseBody); } }
