I am trying to follow the "Rust and WebAssembly" Tutorial. I am at the point where we are adding tests, Testing Life - Rust and WebAssembly. The problem is that I keep getting an error that it cannot find the wasm_game_of_life crate even through that is the crate the test is in.

tests\web.rs:
//! Test suite for the Web and headless browsers.

#![cfg(target_arch = "wasm32")]

extern crate wasm_bindgen_test;
use wasm_bindgen_test::*;

extern crate wasm_game_of_life;
use wasm_game_of_life::Universe;

wasm_bindgen_test_configure!(run_in_browser);
...

I am getting the following error when I run wasm-pack test --chrome --headless and I cannot figure out why.

PS C:\Users\<user>\Rust\wasm-game-of-life> wasm-pack test --chrome --headless
[INFO]: Checking for the Wasm target...
