如何在Swift中进行UITest的UIButton图像更改？

Question

当我点击UIButton时，图像应更改以反映其新状态（例如，记录->暂停等）。

在我的XCode UITest函数中，如何在点击以断言其图像已正确更改为正确图像的.png文件后询问按钮当前图像？

Answer 1

我是这样做的

// Find the button by the image name
// In this example the image's names are "record_image" and "pause_image"
// "_" are replaced by " " in the image name when searching
let recordButton = XCUIApplication().buttons["record image"]
recordButton.tap()
XCTAssertFalse(recordButton.exists) // Record button won't exist anymore since the image has changed
let pauseButton = XCUIApplication().buttons["pause image"]
XCTAssertTrue(pauseButton.exists)
pauseButton.tap()
XCTAssertFalse(pauseButton.exists)
XCTAssertTrue(recordButton.exists)
