UI Testing - Astronomy

Introduction

The goal of this project is to write UI tests for the given project in this respository.

Instructions

Please fork and clone this repository. It contains a modified version of the Astronomy that you should use. This project is set up so you can test the UI without having to worry about the uncertainty that network calls bring into the application. This is done by using local data when running UI tests.

Part 1 - Prepare the application for UI testing

1. Add a new UI testing target to the project.
2. In the setUp() method of the AstronomyUITests class that comes with your UI test target, create a constant for the application (let app = XCUIApplication)
3. Set the app's launchArguments to ["UITesting"]. This string is the launch argument that the application will look for to know that it use local data instead of making network calls.

Part 2 - Writing the tests

Create a test for every interaction you can think of. To get you started:

• Test saving a photo. WARNING: You must manually run your app in the simulator and accept the permissions for Photo Library access in the alert controller that appears when you tap the save photo button in the detail view controller of a photo. If you do not do this, you will be unable to write a successful test for saving a photo.
• Test viewing another sol (Note that since you're using local data, there will only be 3 sols (sols 14-16)

You should be able to write at least 4 tests. If you're stumped on tests to write, it can be helpful to think about how a normal user would interact with the app.

Go Further

• Create UI tests for a previous project that you've made at Lambda School that does not include networking or concurrency.

AND/OR

• For an added challenge, create UI tests for the Journal app. This will require you figure out how to use local "mock" data in order to avoid performing network calls in your tests. For some help on starting with that, refer to the following in the Astronomy project:
  • In the Resources folder, there is a folder called "UI Testing" that has the mock data.
  • The "IsUITesting.swift" file
  • From there, use "Find in Project" (Command + Shift + F) and search for "if isUITesting" to show where the project has been modified to account for using the mock data instead of performing network calls.
