Is it possible to mock the tauri API functions?

[fortserious]

I'm implementing e2e testing with Selenium and Webdriver (and am grateful to https://github.com/bukowa/tauri-e2e for helping me get started on that), and it's become necessary to mock some file dialog APIs.

I believe the only course of action is to re-implement my own wrappers for tauri_api::dialog and use mockIPC to intercept those, but before I do that I wanted to see if there was a better way.

Thanks!

I've tried a few more things and I'd like to amend my question to "Is it possible at all to mock the backend in a Selenium/Webdriver environment"?

I'll explain the specific case I'm trying to test in case that helps: Instead of opening a tauri dialog to attaching a file, I'd like to return my test file path.

It seems to me like I could probably override the 'tauri' command like so:

mockIPC((cmd, args) => { // simulated rust override for tauri api commands if(cmd === "tauri") { // override tauri api functions here } });

However, when attempting to use mockIPC from a mocha test suite, I get the error that window is undefined.

Is there an officially-supported method to create backend mocks when doing e2e tests in Selenium/Webdriver, or is that reserved specifically for Vitest?

The way I see it, there are two courses I can take:

• Implement a wrapper for all the Tauri API commands I use and then, based on some setting triggered in a before() call, call a custom mock library. This seems overly complex.
• Use robotjs/nut-js/AutoHotkey as part of the CI environment in order to enter the test file path into the tauri dialog. Seems hacky, but preferable to the above solution.

Am I approaching this the correct way?

I'll close this as I was able to find a different solution.

I'm now using keysender for desktop automation and using that to direct the tauri dialogs to my test files.

I now have full e2e testing working on my app!
