### Start Lamdera Development Server for Visual Testing

Source: https://github.com/tibastral/program-test-boilerplate/blob/main/README.md

This command initiates the Lamdera development server, which is crucial for visually observing program-tests in action. Once the server is running, you can access the test runner in your browser to watch tests step-by-step and debug layout or rendering issues interactively.

```Shell
lamdera live
```

### Example End-to-End Test in Elm using Program-Test

Source: https://github.com/tibastral/program-test-boilerplate/blob/main/README.md

This Elm code snippet provides a typical example of an end-to-end test using the program-test framework. It demonstrates how to simulate user interactions like inputting text into a DOM element and clicking a button, followed by asserting the presence of specific text content in the rendered view. The test starts a frontend session and defines a sequence of client actions.

```Elm
helloWorldTest : TF.EndToEndTest ToBackend FrontendMsg FrontendModel ToFrontend BackendMsg BackendModel
helloWorldTest =
    TF.start "Test Hello World"
        (Time.millisToPosix 0)
        config
        [ TF.connectFrontend
            100
            (sessionIdFromString "session1")
            "/"
            { width = 900, height = 800 }
            (\client ->
                [ client.input 100 (Dom.id "best-framework") "react"
                , client.click 100 (Dom.id "save-the-world")
                , client.checkView
                    100
                    (Test.Html.Query.has
                        [ Test.Html.Selector.text "Thank you, Mario, but the slowness is in another framework"
                        , Test.Html.Selector.text "Take that, react"
                        ]
                    )
                ]
            )
        ]
```

### Run Lamdera Program-Tests with elm-test-rs

Source: https://github.com/tibastral/program-test-boilerplate/blob/main/README.md

This shell command executes end-to-end tests written with program-test using the `elm-test-rs` runner. It specifies the Lamdera compiler to ensure compatibility with the Lamdera ecosystem. This is the standard way to run your program-tests from the command line.

```Shell
elm-test-rs --compiler lamdera
```
