This simple test fails in my project. Similar code in my application also crashes.
How do I debug the problem?
What project settings are required. I have added SwiftData as a framework to test (and application) targets?
Thanks,
The problem is with:
modelContext.insert(item)
Thread 1: EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0)
import XCTest
import SwiftData
@Model
class FakeModel {
var name: String
init(name: String) { self.name = name }
}
@MainActor
final class FakeModelTests: XCTestCase {
var modelContext: ModelContext!
override func setUp() {
super.setUp()
do {
let container = try ModelContainer(for: FakeModel.self, configurations: ModelConfiguration(isStoredInMemoryOnly: true))
modelContext = container.mainContext
} catch {
XCTFail("Failed to create ModelContainer: \(error)")
modelContext = nil
}
}
func testSaveFetchDeleteFakeItem() {
guard let modelContext = modelContext else {
XCTFail("ModelContext must be initialized")
return
}
let item = FakeModel(name: "Test")
modelContext.insert(item)
let fetchDescriptor = FetchDescriptor<FakeModel>()
let items = try! modelContext.fetch(fetchDescriptor)
XCTAssertEqual(items.count, 1)
XCTAssertEqual(items.first?.name, "Test")
modelContext.delete(item)
let itemsAfterDelete = try! modelContext.fetch(fetchDescriptor)
XCTAssertEqual(itemsAfterDelete.count, 0)
}
}
