Expected vs Actual Snapshot

Introduction

In this article, we will explore the issue of assertSnapshot not generating the accessibility panel when used with Tuist and SwiftPM. We will delve into the possible causes and provide a solution to this problem.

Understanding the Issue

The assertSnapshot function is a crucial part of snapshot testing, which allows developers to verify that their UI components behave as expected. However, when used with Tuist and SwiftPM, this function fails to generate the accessibility panel. This issue can be frustrating, especially when trying to integrate the library in a project.

Project Setup

To reproduce this issue, we need to set up a project using Tuist and SwiftPM. The project should include the AccessibilitySnapshot library, which provides the assertSnapshot function. We can use the following code to set up the project:

// tuist.yml
targets:
  - name: AccessibilitySnapshotTuist
    type: application
    platform: ios
    dependencies:
      - name: AccessibilitySnapshot
        version: 1.0.0

// Package.swift
// swift-tools-version:5.6
import PackageDescription

let package = Package(
    name: "AccessibilitySnapshotTuist",
    platforms: [
        .iOS(.v14)
    ],
    products: [
        .executable(name: "AccessibilitySnapshotTuist", targets: ["AccessibilitySnapshotTuist"])
    ],
    dependencies: [
        .package(url: "https://github.com/cashapp/AccessibilitySnapshot.git", from: "1.0.0")
    ],
    targets: [
        .target(name: "AccessibilitySnapshotTuist", dependencies: ["AccessibilitySnapshot"])
    ]
)

Expected vs Actual Snapshot

When using the assertSnapshot function, we expect to see the accessibility panel. However, in this case, the panel is not generated. The expected snapshot is shown below:

This is the expected Snapshot	This is what I'm getting

Possible Causes

There are several possible causes for this issue:

Missing Accessibility Configuration: The accessibility configuration might be missing in the project. This configuration is necessary for the accessibility panel to be generated.
Incorrect Snapshot Configuration: The snapshot configuration might be incorrect. This configuration is necessary for the snapshot to be generated correctly.
Tuist and SwiftPM Issues: There might be issues with Tuist and SwiftPM that are causing the accessibility panel to not be generated.

Solution

To solve this issue, we need to ensure that the accessibility configuration is correct and that the snapshot configuration is also correct. We can do this by:

Adding Accessibility Configuration: We need to add the accessibility configuration to the project. This can be done by adding the following code to the Info.plist file:
