Type mismatch: PlayerRowView is not HStack || but it is. about viewinspector HOT 3 CLOSED

OK - resolved my issue - and YES - it was ALL me.

I just finished a TDD course with James Grenning https://wingman-sw.com - and by watching his process very closely and comparing it to mine... well - he moves in tiny steps - verifies that each step compiles/links/works before moving on to the next one. So I decided to apply that method to my testing of PlayerRowView...

I thought - heck - I've not validated the unit-testing system works - I just assume it SHOULD! [foreshadow - I will end up with should all over me]

I decided to install the example ContentView example with the classic "Hello World" and see if that test will pass.
So going BACK to the instructions in Guide.... I copied the ContentView:

struct ContentView: View {
    var body: some View {
        Text("Hello, world!")
    }
}

Then I copied the example UI Test

import XCTest
import ViewInspector // 1.
@testable import MyApp

extension ContentView: Inspectable { } // 2.

final class ContentViewTests: XCTestCase {

    func testStringValue() throws { // 3.
        let sut = ContentView()
        let value = try sut.inspect().text().string() // 4.
        XCTAssertEqual(value, "Hello, world!")
    }
}

I don't know if you SEE IT... - but I did! the STEP #2
extension ContentView: Inspectable {}

I'd not written that in my test!

Reflecting... I want to BLAME the document... it leaves that out of the subsequent example code... OK fair. I skipped to them thinking I had all the setup I needed (WRONG). Could we get a better error message.... I don't know... could the ViewInspector validate that the test case extends or implements the Inspectable protocol? Seems like it could - maybe should.

Anyway - JAMES GRENNING FOR THE WIN!!! To go really really fast - you are going to need to SLOW d..o..w..n.

Thanks James!

Hey David, I did check the podcast you were on and got lots of gotchas where the confusion comes from when using the library (thanks!), so I know there I should put more descriptive error messages. As for the place where you stuck, you almost got it right - for inspecting the PlayerRowView inside the ContentView you need to use .view(PlayerRowView .self) in the chain. You typed .view() at some point, and code autocomplete would have helped you if you didn't have .hStack or something else in the tail.
