So I downloaded the beta of XCode 7 and I've created some UI tests, but I can't find the functionality of how to take screenshots of my app/UI during the test.
Can someone please help?
How do I take screenshots of my UI with Xcode 7 during UI Testing?

UI Testing in Xcode automatically takes screenshots of your app after every step.
Simply go to one of the tests that has already ran (Report Navigator > choose a Test), then start expanding your tests. When you hover your mouse over the steps, you will see eye icons near each step that has a screenshot.
Here's an example... in this case, notice the eye icon at the end of the gray row. If I were to tap on it, I would see a screenshot of the app right when the button in my app was tapped (since the step is Tap the "Button" Button).
Does this work in XCode 7.1 ? I am not able to see the same. Also through this process, XCode will take screenshots for Failed test cases as well ? –

In Xcode 7.1 right click on the test and select "Jump to report". –

Is there a way to reference these screenshots from within the tests themselves? That would allow us to compare the result of an action to the desired result. Is that possible? –

These eye icons are not appearing for me in Xcode 7.3beta5 (7D162j). –

@LeMotJuiced This can be used to analyze the results of a test and figure out why it broke, but it can't be used for perceptual difference testing. The screenshot is not available to the test code. –

If you want to generate screenshots, you can also use snapshot, which describes how to trigger screenshots in UI tests: https://github.com/fastlane/fastlane/tree/master/snapshot#how-does-it-work
It basically rotates the device to .Unknown (Source), which triggers a snapshot without actually modifying your app's state.
Comparing the output with the generated plist file enables you to even properly name the screenshot
fastlane snapshot and deliver works great when generating app store screenshots. However I'm looking for a solution to generate a static website from snapshots which is targeted towards purely UITests. For example screenshots batches are separated based on test cases+devices+language. Can we have such a flavor in snapshot in future or do you know any alternative? –

Can you not use
snapshot for that? –
Handgun I can. And of course I'm using
snapshot. I just want a different template for generated static web page.(A separation of image batches based on the test) which I'm working on. I was wondering if there anything already available. –
Gerhard Facebook's ios-snapshot-test-case and KIF both run as Unit Tests, and therefore are in the same process as the app. As such, they can directly access views and use something like renderView: or snapshotViewAfterScreenUpdates. Xcode UI Testing runs in a separate process, and therefore cannot directly access the views.
UI Automation, Apple's now-deprecated Javascript UI testing library, had a function calledcaptureScreenWithName.
Unfortunately, the new Xcode UI Testing lacks any similar function in its testing library, which to me seems like a glaring omission and I encourage you to submit a Radar for it, as taking screenshots is fundamental to perceptual difference tests (which it sounds like you're trying to do). I hope (and expect) that able will address this deficiency in later Xcode updates.
In the meantime, there are more creative approaches to taking screenshots. See this stack overflow response for a workaround involving taking the screenshot in the app itself and then sending it to the test process.
I' ve created a tool that saves the tests last n screenshots and generates the JUnit tests results report, parsing TestSummaries plist file from test logs. https://github.com/nacuteodor/ProcessTestSummaries
Maybe, that helps you.
Can I ask you to take a look at How to offer personal open-source libraries? please? –

Facebook's FBSnapshotTestCase can be alternative solution:
