A demo for how to setup testing with fastlane in Swift.
This demo tests the uitest by screenshot with Fastlane.

• Before starting

Before you using this demo, install fastlane first.
See here to install fastlane.

• Start demo

After installed, create a project with some ui.
In this demo, we have two page, the first page(PageOneVC) and second page(PageTwoVC).
And having a button in PageOneVC, a label in PageTwoVC.
Just to let you known that they are not the same page.

• What we want to test?

1. When we first enter the PageOneVC, the button will show "first_in".
2. When tapping the button, it will go to PageTwoVC.
3. Then tapping the back button on the navigatoin bar.
4. And we back to PageOneVC, the button will show "viewWillAppear".

By knowning what we want to test, we can use the XCUIApplication, XCUIElementQuery and XCTAssert to test.

1. Lanch app.
2. Check the button named "first_in" and the button named "viewWillAppear" exist or not.
3. Tap the button.
