@iOhYesPodcast Just finished an iOS bootcamp, no CS degree, minimal developer experience. Job hunt as Jr. Dev has been rough. Any advice?— Sean Allen (@SeanA0400) October 16, 2015

Apple’s new UI testing in Xcode
* Requires iOS 9/Mac OS X 10.11
Test Recording
Leverages “Accessibility”
UI Testing Targets
API components
Assertions, XCTAssert
Elements, XCUIElement
Proxy for UI things, exposes object type and accessibility label
Queries, XCUIElementQuery
Tree navigation, similar to XPath
Relationships and Filtering
“app.tables” is actually a convenience method for app.descendantsMatchingType(‘table’)
Application, XCUIApplication
Proxy for the application under test, separate and new process
Dealing with Gotchas
Simulating events
No long press, roll your own with pressForDuration
No 3d touch press (AFAIK)
Wait for…
using waitForExpectationsWithTimeout
without an explicit wait, a total of 3 attempts will be made to resolve a query before failing
Race conditions
Item not visible to accessibility
Note: “isAccessibilityElement” does NOT need to be true in order to be “visible to accessibility”
