2. Agenda Prelude An Ancient World Forget Physical Laws Layered World Parallel Worlds
3. Prelude
6. Test .NET Code with Specflow
7. Test .NET Code with Specflow Drive a Windows App Using White
8. Test .NET Code with Specflow Drive a Windows App Using White Test Windows GUIs with AutoIt
11. An Ancient World
13. Not for everyone
14. For some many of us this is more accurate…
16. Our context
20. Do desktop applications still make sense?
21. IF you have to integrate with low-level SDKs And…
22. IF client app requires low latency IF you have to integrate with low-level SDKs And…
23. AND your stress tests look like this…
34. Forget Physical Laws
35. Test automation with physical devices ?!
37. Not great to maintain…
38. char[] start_scan() char[] capture() char[] scan_finger()
39. Plain Old Interfaces
40. byte[] start_scan();
41. byte[] start_scan();
42. Decoupled Development x. Device Integration y. Application Biometric Logic
43. Decoupled Development x. Device Integration y. Application Biometric Logic
44. Decoupled Development x. Device Integration y. Application Biometric Logic
45. byte[] start_scan();
46. byte[] start_scan();
47. byte[] start_scan();
48. byte[] start_scan();
49. Requires: Categorized Test Data Supports: Randomization
50. Requires: Categorized Test Data Supports: Randomization
51. byte[] start_scan();
54. Virtual Fingerprint Scanner
55. Given a complete Visa application When I capture 4 valid fingerprints Then application is sent for approval Virtual Fingerprint Scanner
56. Given a complete Visa application When I capture 4 valid fingerprints Then application is sent for approval Virtual Fingerprint Scanner
57. Given a complete Visa application When I capture 4 valid fingerprints Then application is sent for approval Virtual Fingerprint Scanner
58. Given a complete Visa application When I capture 4 valid fingerprints Then application is sent for approval Virtual Fingerprint Scanner
59. Given a complete Visa application When I capture 4 valid fingerprints Then application is sent for approval Virtual Fingerprint Scanner
60. Given a traveler leaving the country When 1 finger is missing Then emigration supervisor is called Virtual Fingerprint Scanner
61. Forget Physical Laws Problem Automate testing of applications using physical devices Ingredients • Common interface for similar devices • Virtual device implementation for that interface • Categorized test data repository • Test data sampler
62. Layered World
63. Reusable core modules but Many customizations and Specific client requirements ?
64. Reusable core modules but Many customizations and Specific client requirements ?
65. Reusable core modules but Many customizations and Specific customer requirements ?
67. Plain Old Layers
69. Low level UI automation across all apps
70. Low level UI automation across all apps
71. Low level UI automation across all apps Module “object” automation
72. Low level UI automation across all apps Module “object” automation
73. Low level UI automation across all apps Module “object” automation Application logic automation
74. Low level UI automation across all apps Module “object” automation Application logic automation
75. Low level UI automation across all apps Module “object” automation Application logic automation
76. Application Driver DSL
77. Given a traveler entering the country When I capture all biometric data And no alarms are raised Then travel is allowed Application Driver DSL
78. Given a traveler entering the country When I capture all biometric data And no alarms are raised Then travel is allowed Application Driver DSL
79. Given a traveler entering the country When I capture all biometric data And no alarms are raised Then travel is allowed Application Driver DSL
80. Layered World Problem Automate testing of reusable client modules with project customizations and specific requirements Ingredients • Specflow (Cucumber family) • White (GUI automation) • Layered test code: pure UI + module + application DSL
81. Parallel Worlds
82. Multiple public-facing interfaces GUI vs API
83. Multiple public-facing interfaces GUI vs API
84. OR
85. Multiple execution alternatives GUI objects vs Keyboard shortcuts
86. Multiple execution alternatives GUI objects vs Keyboard shortcuts
87. Plain old Dependency Injection
90. FingerprintsUI
91. FingerprintsUI
92. FingerprintsUI FingerprintsShortcuts … IFingerprints
93. FingerprintsShortcuts IFingerprints Given a complete Visa application When I capture 4 valid fingerprints Then application is sent for approval FingerprintsUI
94. FingerprintsShortcuts IFingerprints Given a complete Visa application When I capture 4 valid fingerprints Then application is sent for approval FingerprintsUI Fingerprint.IFingerprints = Fingerprint.FingerprintsUI
95. FingerprintsShortcuts IFingerprints Given a complete Visa application When I capture 4 valid fingerprints Then application is sent for approval FingerprintsUI Fingerprint.IFingerprints = Fingerprint.FingerprintsUI
96. FingerprintsShortcuts IFingerprints Given a complete Visa application When I capture 4 valid fingerprints Then application is sent for approval FingerprintsUI Fingerprint.IFingerprints = Fingerprint.FingerprintsShortcuts
97. FingerprintsShortcuts IFingerprints Given a complete Visa application When I capture 4 valid fingerprints Then application is sent for approval FingerprintsUI Fingerprint.IFingerprints = Fingerprint.FingerprintsShortcuts
98. Parallel Worlds Problem Automate testing of multiple interfaces/executions for same scenario Ingredients • A single test interface for the exposed functionality • Two or more implementations of that interface • (Basic) dependency injection mechanism
