I am trying to create a document-based (macOS) app using SwiftUI and SwiftData. I'm trying to set up XCTests to validate my model behaviors.
Clearly, I need to set up a container in my test class for my model objects. Failing to do so shows that SwiftData is trying: my app launches into the New Document dialog; if I dismiss it, the app fails with a "failed to find an active container" for my model object.
Any pointer on setting up a container and context within XCTest is welcome. TIA
After re-watching some of the WWDC video, here's what I've got so far:
final class ModelTests: XCTestCase {
var context: ModelContext?
override func setUpWithError() throws {
// Put setup code here. This method is called before the invocation of each test method in the class.
let schema = Schema([MyModelClass.self])
let config = ModelConfiguration(schema: schema, inMemory: true)
guard let container: ModelContainer = try? ModelContainer(for: schema, configurations: [config]) else {
XCTFail("Failed to set up model container")
return
}
context = ModelContext(container)
}
…
I feel like this gets me to the point where I can test the functionality of my model objects, and probably test persistence by re-fetching objects from the store.
Comments and questions welcome.
