```

```reason

open Fest;

module RTL = ReactTestingLibrary;

[@mel.get] external textContent: Dom.element => string = "textContent";

Domloader.init();

module Hello = {

  [@react.component]

  let make = (~text) => 
 {"Hello " ++ text |> React.string} 
;

};


let () =

  test("test component", () => {

    let result = RTL.render();

    // Check that Hello component renders the name properly.

    let el = RTL.getByText(~matcher=`Str("Hello Nila"), result);

    expect |> equal(textContent(el), "Hello Nila");

  });

```

## Commands

Run all tests:

```bash

make test

```
