The document discusses web services and their functionalities, emphasizing their use in automation and testing. It provides insight into testing methods, the role of Quality Assurance (QA) in this context, and examples of using tools like Postman and programming languages like Java and Python for automation. Key takeaways include understanding web services, their testing approaches, and enhancing test automation familiarity.
Increase automation to rest
- 1. Increase Automation to REST Understanding Web Services and how to test them Shiva and Fiona
- 2. Key Take Aways: ❏ What Web Services are and why we use them ❏ How to test a Web Service in multiple ways ❏ Increased familiarity with test automation
- 3. Web Services ● Interface to provide access to functionality ● Uses HTTP/HTTPS/SMTP for communication ● Communicates using JSON/XML/CSV/Plain Text etc.
- 4. When and Why Same functionality multiple UIs: ● Customise cross platform ● Multiple apps ● Different vendors Being able to implement one service and use that functionality across all these different displays
- 5. Let see an example! ...things get clearer when you can see them :)
- 6. An Example Website serving request: Weather Underground Underlying HTTP request: curl -X GET http://api. wunderground. com/api/e896598d74613088/conditi ons/q/zmw:00000.1.43128.json
- 7. Another Example Booking a ticket with Orange Bus via different agencies RedBus UI TravelYari UI Orange Bus UI Book a seat Book a seat Get bus details Orange Bus Web Service
- 8. REpresentational State Transfer (REST) ● Uses HTTP(S) for CRUD operations ● Uniform Resource Identifiers (URIs) ● New alternative to SOAP
- 10. What about APIs? ● Part of the web service which receives requests/sends responses ● Has one or more endpoints ● Documented contract
- 11. Requests and Responses ...lets see some examples...
- 12. Request Request: URI Method Headers DATA
- 14. Requests Common request types: ● GET ● POST ● PUT ● DELETE
- 15. Response Codes Outcome of a request: ● 1xx - Informational ● 2xx - Success ● 3xx - Redirection ● 4xx - Client Error ● 5xx - Server Error
- 22. QAs and Web Services ...based on our experiences testing web services out in the wild...
- 23. How testing helps ● Business issues first then the presentation issues ● Early feedback ● Debug in different layers ● Save time retesting ● More confident app works ● Release more frequently ● Lots more….
- 24. The role of QAs
- 25. Demo - try it yourself!
- 26. Manual in browser test https://petal-spirit.hyperdev.space/
- 28. curl Sample Curl Request: curl -X GET https://petal-spirit.hyperdev.space/dreams -H "Content-Type: application/json" -i > curl _
- 29. Alternatives? Cocoa Rest Client IntelliJ REST Plugin
- 30. Let’s automate it! - Java Use Library: UniRest (Java) Sample Test Scenario public class TestDreams { @Test public void testGetDreams() throws UnirestException { System.out.println("Testing Get Dreams....."); String url = "https://petal-spirit.hyperdev.space/dreams"; HttpResponse<JsonNode> jsonResponse = Unirest.get(url) .header("Content-Type", "application/json").asJson(); Assert.assertEquals(200, jsonResponse.getStatus()); Assert.assertNotNull(jsonResponse.getBody()); } }
- 31. Let’s automate it! - Python Use Package: Requests (Python) Sample Test Scenario import unittest import requests class TestDreams(unittest.TestCase): def setUp(self): self.url = 'http://petal-spirit.hyperdev.space/dreams' def test_should_verify_get_dreams(self): print("Verifying Get Dreams....") headers = {"Content-Type": "application/json"} res = requests.get(url=self.url, headers=headers, verify=False) self.assertEqual(200, res.status_code, "Response code doesn't match") self.assertTrue(res.json())
- 32. Closing notes ...time flies when you’re automating tests...
- 33. Suggestions ● Test as you go ● Cross role pairing ● Integrate with build pipeline ● If the service is broken no need to test UI ● Spread the word! :)
