Automation Tests at Babylon
What we will talk about: — What issues do we
face in UI tests — How do we solve them — BDD-style UI tests — Tooling
What we will not talk about: — Why — How
— What to test
What issues do we face? — unexpected failures — performance
— scenarios hard to automate & hard to test manually
Content stability
External system actions required — start/complete appointment — subscribe prescription
— answer patient question — etc
Network stability* * https://techcrunch.com/2016/07/13/facebook-lifts- the-veil-on-its-mobile-device-lab
Performance Repeated test steps — register new user — open
Appointments tab — enter your symptoms — book an appointment — add payment method — confirm payment
large tests, faster test suite vs focused tests, slower test
suite
How do we solve that?
Control the World** — Control the network — Control the
initial state of the app ** C. Montgomery Burns' Handbook of World Domination By Matt Groening.
How to control the network control == own data
How to control the network — from inside the app
— from inside the test runner
From inside the app - in-app stubs — straightforward ✅
— integrates in application code — not very flexible ❌
From inside test runner - local web server — harder
to setup ❌ — integrates in test runner ✅ — very flexible ✅
Local server setup In the app: — switch environment
Local server setup In the app: — allow local networking
in the app
Local server setup In the test: — web server implementation
(Ambassador, GCDWebServer, swifter, Kitura, SwiftNIO, ...) — request interception
Local server setup In the test: — web server implementation
(Ambassador, GCDWebServer, swifter, Kitura, SwiftNIO, ...) — request interception
Local server edge cases — Parallel testing — Absolute urls
in responses — Overriding response size
Local web server use cases — Logging — Snapshots —
Full mocks
Network session recording — Record and replay using mock URLSession
(Vinyl, DVR) — detect recording mode — configure matching strategy — create URLSession mock
Network session recording — Record random test input — match
full request — record random body data in a file
Network session recording — Override current date
Mocked backend — mock everything ❌ — a lot of
boilerplate code to write — total control ✅
Network stability Content stability ✅
Tests performance
Tests performance Shortcuts via launch arguments — Special feature toggles
— User defaults overrides — Memory storage
Tests performance API calls from tests — to register a
new user — to add a family member — to book an appointment — etc
