Manjyot Singh and Ruchika Rawat gave an introduction to API testing using REST-Assured. They discussed the basics of REST and SOAP, and how REST-Assured can be used to test GET, POST, PUT, and DELETE requests. They also covered response parsing, JSON parsing, authentication, and provided references for further reading.

3. What is a web service – QA point of view?
A method of communication between two web applications

7. REST Vs SOAP

8. ???

9. SOAP
● Simple object access protocol.
● Used for exchange of information on distributed platform using XML.
● Works mainly with HTTP, HTTPS.
● HTTP makes SOAP go around firewalls.
● Slower when using large XML messages.

10. ???

11. REST
● Representational State Transfer.
● REST architectural style, data and functionality are considered
resources and are accessed using Uniform Resource Identifiers
(URIs).
● Resources are manipulated using a fixed set of four create, read,
update, delete operations: PUT, GET, POST, and DELETE.
● Formats - XML, plain text, PDF and JSON.

12. REST - Example
ResponseRequest
http://localhost:9000/users/1

13. Let’s talk about...

14. Why REST-assured ?
● Java Domain Specific Language (DSL) for testing web services
● Built on top of HTTPBuilder
● Supports response parsing
● Supports in-built assertions
● Supports BDD syntax

15. Setup (Requirement)
● Install JDK
● IDE (Eclipse/Intellij)
● Build Tool (gradle) *optional
● Rest-assured jars
● Hamcrest-matchers jars
● Junit jars

16. Understanding a Request

17. Simple GET Request
given().
contentType(“application/json”).
when().
get("/users").
then().
assertThat().
statusCode(HttpStatus.SC_OK);

18. GET Request
given().
contentType(“application/json”).
when().
get("/users/1").
then().
assertThat().
body("userId", equalTo(1)).
body("userName", equalTo("Robert")).
body("employer", equalTo("facebook")).
body("location.state", equalTo("California")).
body("location.city", equalTo("San Jose"));

19. POST Request
given().
contentType("application/json").
body("[{"userName":"Jayant2","employer":"Google","location":{"
state":"California","city":"Mountain View"}}]").
when().
post("/users").
then().
assertThat().
body("userName", hasItems("Jayant2"));

20. PUT Request
int userId = 1;
given().
contentType("application/json").
when().
body("{"userName":"Taylor"}").
put("/users/" + userId).
then().
statusCode(HttpStatus.SC_OK).
body("userName", equalTo("Taylor"));

21. DELETE Request
int userId = 9;
given().
when().
delete("/users/" + userId).
then().
statusCode(HttpStatus.SC_OK);

22. Response parsing
Response response =
given().
contentType(ContentType.JSON).
when().
get("/users/5").
then().
extract().response();
String userName = response.path("userName");
String userCity = response.path("location.city");
Assert.assertTrue(userName.equals("Steve"));
Assert.assertTrue(userCity.equals("San Francisco"));

23. Json parsing
String jsonResponse =
get("/users/5").
asString();
JsonPath jsonPath = new JsonPath(json).setRoot("location");
String state = jsonPath.getString("state");
String city = jsonPath.getString("city");
Assert.assertTrue(state.equals("California"));
Assert.assertTrue(city.equals("San Francisco"));

24. Authentication
String sessionToken =
given().
body("{"userName" : "ruchikar","password" : "P@ssW0rd"}").
when().
with().
header("Content-Type", "application/json").
header("X-Forwarded-Proto", "https").
post("/sessionTokens").
then().
statusCode(200).
contentType(ContentType.JSON).
extract().
response().path("response.sessionToken");

25. given().
when().
with().
header("X-Forwarded-Proto", "https").
header("Content-Type", "application/json").
header("X-Auth", sessionToken).
get(“/users”).
then().
statusCode(HttpStatus.SC_OK).
contentType(ContentType.JSON);
