[docs] WebDriver (Selenium and WebdriverIO) e2e testing does not work.

[ospfranco]

I'm trying to setup end-to-end tests for Tauri. I've followed the official documentation but when I try to start my tests I get the following error:

** (pulsar:12894): WARNING **: 06:38:47.744: Disabled hardware acceleration because GTK failed to initialize GL: Unable to create a GL context.

** (pulsar:12894): WARNING **: 06:38:47.751: webkit_settings_set_enable_offline_web_application_cache is deprecated and does nothing.

  1) "before all" hook in "{root}":

      at Context.<anonymous> (test/test.js:47:16)

The application starts correctly when I launch it manually. But fails without a reason in the selenium test. Any idea what could be wrong or how can I get a more descriptive error? Are the docs up-to-date? Migration to v2 is not possible for us at the moment, just need to get the tests running, any help is much appreciated.

I decided to give webdriverio a test. Again following the official docs. This time it gets further. The app starts and there is some console output. But the tests never start running. Am I missing something?

My app starts and when I minimize it I see on the console nothing is running.

I have tried updating the wdio dependencies to the latest versions, but I get other errors.

Any feedback @FabianLars ?

When I leave the test running my linux vm hangs and dies. But I've manage to retrieve a log where there is a request failure:

You can see there is a Request timed out! response. When I call the endpoint http://localhost:4444/session manually I do get a response:

debian@debian:~/Developer/pulsar/wdio$ curl -X POST http://localhost:4444/session -H "Content-Type: application/json" -d "{\"capabilities\":{\"alwaysMatch\":{\"tauri:options\":{}},\"
firstMatch\":[{}]},\"desiredCapabilities\":{\"tauri:options\":{\"application\":\"../src-tauri/target/release/pulsar\",\"webviewOptions\":{}}}}"
{"value":{"sessionId":"be344bce-7ba2-492a-923f-b39062057565","capabilities":{"browserName":"MiniBrowser","browserVersion":"2.44.2","platformName":"linux","acceptInsecureCerts":false,"strictFileInteractability":false,"setWindowRect":true,"unhandledPromptBehavior":"dismiss and notify","pageLoadStrategy":"normal","proxy":{},"timeouts":{"script":30000,"pageLoad":300000,"implicit":0}}}}

Maybe the script is missing permissions? I need another console?

I am seeing similar behavior

Here are capabilities that work for me without tauri-driver wrapper https://github.com/bukowa/tauri-e2e/blob/605a3ec1a3dbce14105d1a8576a1aa7f6fd34dfd/selenium/javascript/src/selenium/webkitgtk2.ts
