Network Testing

Introduction to Szimpla, a network testing library based on Snapshots that have been recorded before.

1. NETWORK TESTING @PEPIBUMUR - IOS DEVELOPER AT SOUNDCLOUD
2. HOW MANY OF YOU IMPLEMENT UNIT TESTS IN YOUR PROJECTS? !
3. SPECTA, EXPECTA, OCMOCK, OCMOCKITO, QUICK, NIMBLE, KIWI, OCHAMCREST
4. WE TEST UNITS OF CODE !
6. ! CAN WORK AS EXPECTED ↔ BUT NOT THE INTEGRATION
7. INTEGRATION TESTS
8. WE TEST THE UNITS OF CODE AS A SYSTEM ! ↔ !
10. BUT... YOUR COMPONENTS ARE USED BY VIEWCONTROLLERS
11. AND THESE ONES HAVE A LIFECYCLE !
12. CONTROLLED BY YOUR APPLICATION USERS !
13. ! ARE PART OF THE SYSTEM
14. ! ↔ # ↔ !
15. AND WE SHOULD TEST IT... DON'T WE? !
16. HOW MANY OF YOU IMPLEMENT ACCEPTANCE TESTS IN YOUR PROJECTS? !
18. THEY RELY ON ACCESSIBILITY THUS, THE UI LAYER
19. let app = XCUIApplication() app.launch() app.buttons["Stream"].tap() app.tables.staticTexts["Enrique Iglesias"].tap()
20. WE TEST FROM THE USER'S VIEWPOINT
21. BUT...
22. NON-UI STUFF (THAT DEPENDS ON THE VIEWS LIFECYCLE) IS ALSO TAKING PLACE
23. ! NETWORKING
24. !THAT REFLECTS ON UI API INTERACTION !THAT DOESN'T REFLECT ON UI ANALYTICS
25. API INTERACTION CAN BE TESTED WITH ACCEPTANCE TESTS
26. let app = XCUIApplication() app.launch() app.buttons["Stream"].tap() //-----> REQUEST SENT waitForContent(timeout: 5) let enriqueCell = app.tables.staticTexts["Enrique Iglesias"] enriqueCell.tap() // -----> REQUEST :+1:
27. BUT ANALYTICS...
28. let app = XCUIApplication() app.launch() app.buttons["Stream"].tap() //-----> SCREEN EVENT SENT let enriqueCell = app.tables.staticTexts["Enrique Iglesias"] enriqueCell.tap() // -----> WAS IT REALLY SENT?
29. THIS IS EVENT IS NOT SENT
30. THIS IS EVENT IS NOT SENT THIS EVENT IS SENT WITH WRONG PARAMETERS
31. WHAT CAN I DO THEN? ! (ANALYTICS MIGHT BE CRITICAL FOR YOUR BUSINESS !)
32. SZIMPLA NETWORK TESTING IN SWIFT GITHUB.COM/PEPIBUMUR/SZIMPLA
34. ONLY ! STEPS
35. 1. RECORD THE SNAPSHOT
36. class AppUITests: XCTestCase { func testDefault() { try! Szimpla.Client.instance.start() let app = XCUIApplication() app.buttons["Navigate"].tap() try! Szimpla.Client.instance.record(path: "CMDUConf.json") } }
37. 2. VALIDATE THE SNAPSHOT
38. [ { "url": "https://api.soundcloud.com/tracks/1235123", "parameters": {}, "body": {} } ]
39. [ { "url": "https://api.soundcloud.com/tracks/[0-9]+", "parameters": {}, "body": {} } ]
40. 3. UPDATE THE TEST
41. class AppUITests: XCTestCase { func testDefault() { try! Szimpla.Client.instance.start() let app = XCUIApplication() app.buttons["Navigate"].tap() try! Szimpla.Client.instance.validate(path: "CMDUConf.json") } }
42. LIVE DEMO ! "
43. SPANSHOT APPROACH (INSPIRED BY FACEBOOK SNAPSHOT TESTING)
44. SUPPORTS CUSTOM VALIDATORS
45. public protocol Validator { func validate(recordedRequests recordedRequests: [Request], localRequests: [Request]) throws }
46. SUPPORTS CUSTOM FILTERS
47. public protocol RequestFilter { func include(request request: Request) -> Bool }
48. ANALYTICS TEAM CAN VALIDATE THE SNAPSHOTS IT'S A JSON FILE! ! !
