Setting a Host Application yo my test target

[asalom]

Need/problem

I need to set a specific Host Application to my Target of type .unitTests which tests a Target of type .framework.

Motivation

I have a Target of type .framework which makes use of the Keychain. In order to test the Keychain, the tests have to run in a device, they can't run directly on the framework. In other words, there can't be a Keychain without a Simulator or device.

I've tried to change the test target settings with:

Settings(
  base: [
    "TEST_HOST": "$(BUILT_PRODUCTS_DIR)/HostTarget.app/HostTarget"
  ], 
  configurations: [.debug(name: "Debug"), .release(name: "Release")], 
  defaultSettings: .recommended
)

However, this is not enough and it produces the following configuration, where the Host Application is not being set properly.

I've tried to manually change the Host Application from Xcode user interface, and the changes that are applied to the xcodeproj file include setting TEST_HOST to $(BUILT_PRODUCTS_DIR)/HostTarget.app/HostTarget but also TestTargetID = E4E2F9AB233E5A0600B3CE9B; and this I have no idea how to obtain from the Project.swift file

Visual desired outcome

Hi @asalom

I believe this is already supported

#300

The way to get it working is to add the Application targets as a dependency to the unit test target and that should set the appropriate test host.

We should update the docs to capture this :)

Hope this helps

It worked like a charm, thank you. I will leave my configuration in case someone else faces the same issue.

let tests = Target(
  name: "CommonTests",
  platform: .iOS,
  product: .unitTests,
  bundleId: "com.vodafone.CommonTests",
  infoPlist: "Tests/Info.plist",
  sources: "Tests/**",
  dependencies: [
    .target(name: "Common"), // product is .framework
    .target(name: "HostTarget") // product is .app
  ]
)
