Xcode 7 UI Tests, Recording button is greyed out

问题:

I am trying to add UI tests to my existing project using Xcode 7. However the UI test recording button is always greyed out. What I am missing here?

I tried restarting Xcode, cleaning and rebuilding the project and adding a new UI test target. Does anyone else experience the same behaviour?

回答1:

FWIW: I had this problem and it turns out I was trying to run the simulator in the wrong OS.

I was trying to use iOS8.x, and UITesting only works in iOS9+.

Switch the simulator version, and the record button appears.

To enable the red button, you have to have the cursor on the test method:

I got stuck on this for a while too. In order to record, you have to be in a class that Xcode recognizes as containing tests. Add a file to your UI testing target with something like:

import Foundation
import XCTest

class MyTests: XCTestCase {
    func testSomething() {

    }
}

Save the file, clean your project, and switch to another file then back to this one. Record button should be available then.

I had the same issue and my setup was correct, iOS >= 9.0, target was added.

The problem was Xcode indexing which took for a while (about 1h), after indexing was done, recording button becomes active.

回答5:

Had the same issue on Xcode 8.3.

I have removed the tearDown method

   override func tearDown() {
        super.tearDown()

    }

As didn't need to use it. As soon as I added it back the record button was enabled.

For me, the problem was the "Version Editor" pane was open. As soon as I switched back to the Assistant Editor, it worked.

回答7:

This is kind of silly, but missed out in some articles I read.

Make sure you have a UITesting Target, a regular Test target didn't do it for me.

回答8:

A test method has to begin with the word test for Xcode to recognize it and allow recording when the cursor is inside the method.

One indication that Xcode recognized the method is a rhombus appearing left to the method name:

Check your version editor and correct it

I did a few things to enable my record button:

1. (Optional, Recommended) - Delete all TEST schemes and TEST targets for your project, start fresh by creating a new UITest Target.
2. Make sure that your UITest scheme and main project run scheme point to the same target.
3. Try deleting your other UITest schemes if they can be easily recreated/are not of absolute importance.
4. Product > (Press and hold ALT key) > Clean Build Folder
5. Product > Clean (just for safe measure)
6. Close project, quit Xcode.
7. Quit simulator.
8. Finally, reopen Xcode, load your project. Navigate to your UITest file and the little red button of joy should be available for usage.

Also, make sure that your build/run target is set to iPhone X 9.X.

I've found another solution that I haven't seen listed here.

If you're subclassing XCTestCase, change your class to inherit from that again, save the file, change it back to your subclass name. No clean or build needed.

For my project I've got a sublcass of XCTestCase, let's call it APPMyTestCase. I often find that the record button is greyed out and sometimes the little green/red buttons next to each test method don't appear either to be able to run them individually. If I change my subclass back to XCTestCase for a second everything works again.

Change this:

class APPLoadingPageUITests: APPMyTestCase {
    // tests here
}

To this:

class APPLoadingPageUITests: XCTestCase {
    // tests here
}

And then back to this:

class APPLoadingPageUITests: APPMyTestCase {
    // tests here
}

This fixed it for me.

回答12:

Be sure to only have one subclass of XCTestCase per file. You want the filename and class names to match.

In my experience, even when you have UI tests working, if you add a new subclass of your working XCTestCase subclass in the same file, the record button will be disabled (although all other testing UI will continue to work).

回答13:

As silly as it sounds, I had to select another file from the sidebar on the left and go back to my file with the test cases. After that, the button immediately became active.

回答14:

It immediately came back when I switched to the right scheme. Ensure that you're on the UI testing scheme as the UI test recorder can't work on any other one.

回答15:

You should import the View Class you want to Test. Then put the cursor in the test method.
