Can't get it to work

[filippopassante]

I've specified the example keys and values in the run scheme's environment variables, run the tests in record mode and then with record mode off.

Still, I'm getting the error "/Users/xqc/Library/Mobile Documents/com~apple~CloudDocs/Xcode Projects & Resources/Snapshot/SnapshotTests/SettingsVCSnapshotTests.swift:26: error: -[SnapshotTests.SettingsVCSnapshotTests test_example] : failed - Snapshot comparison failed: Optional(Error Domain=FBSnapshotTestControllerErrorDomain Code=1 "Unable to load reference image." UserInfo={NSLocalizedFailureReason=Reference image not found. You need to run the test in record mode, NSLocalizedDescription=Unable to load reference image., FBReferenceImageFilePathKey=/Users/xqc/Library/Developer/CoreSimulator/Devices/A5B479B7-4DF1-B030-05CAF050B00C/data/Containers/Bundle/Application/629A7F7C-4264-B830/Snapshot.app/PlugIns/SnapshotTests.xctest/ReferenceImages_64/SnapshotTests.SettingsVCSnapshotTests/test_example@3x.png})"

`import iOSSnapshotTestCase @testable import Snapshot

final class SettingsVCSnapshotTests: FBSnapshotTestCase { private var sut: SettingsVC!

override func setUp() {
    super.setUp()
    recordMode = false
    sut = SettingsVC()
}

override func tearDown() {
    sut = nil
    super.tearDown()
}

func test_example() {
    FBSnapshotVerifyViewController(sut)
}

}`

What can I do to figure out the problem?

Thanks

Yep, same issue:

import iOSSnapshotTestCase
import XCTest

@testable import AssertYourself

final class SnapshotTests: FBSnapshotTestCase {

    private var sut: SnapshotsViewController!

    @MainActor
    override func setUp() {
        super.setUp()

        recordMode = false

        let sb = UIStoryboard(name: "Main", bundle: nil)
        let identifier = String(describing: SnapshotsViewController.self)
        sut = sb.instantiateViewController(identifier: identifier)
        sut.loadViewIfNeeded()
    }

    override func tearDown() {
        sut = nil
        super.tearDown()
    }

    func test_zero() throws {
        FBSnapshotVerifyViewController(sut)
    }
}

When I run it with recordMode = true, it generates the image (the image is there, I checked):

2023-11-12 23:49:17.386959+0100 AssertYourself[34842:868152] Reference image save at: /Users/fernando.fernandes/Library/Developer/CoreSimulator/Devices/FA8F811E-B1FF-45FF-995A-ED6F1D93705A/data/Containers/Bundle/Application/0454BE61-CE78-4B5E-80F6-36F75C663A9C/AssertYourself.app/PlugIns/SnapshotTests.xctest/ReferenceImages_64/SnapshotTests.SnapshotTests/test_zeroAndReturnError_@3x.png

But then, running again with recordMode = false produces:

/Users/fernando.fernandes/Downloads/source/backslash-f/assert-yourself/Xcode/Tests/SnapshotTests/SnapshotTests.swift:35: error: -[SnapshotTests.SnapshotTests test_zero] : failed - Snapshot comparison failed: Optional(Error Domain=FBSnapshotTestControllerErrorDomain Code=1 "Unable to load reference image."

It seems the directories don't match the ones set with environment variables:

Environment: Xcode 15.0.1 (15A507) MacBook Pro 13-inch, M1, 2020 MacOS Sonoma 14.1.1 (23B81)

Oh, I get it... When using test plans, the environment variables should be set into the test plan configuration, not the app scheme:

That did the trick on my side. 👍🏻

Thank you so much
