Thank you for the workaround. Based on the explanation, we are bypassing some sort of security restriction. Are there any security concerns with bypassing this restriction? Will this be addressed in the future?

Actually this is not issue of ExTester itself, it is new security feature of AppArmour 24.04 (which is used by Ubuntu 24.04). This workaround disables this security feature of AppArmor, which may expose your system to potential risks, but at the moment that is the only option we are aware.

Another way how to avoid this security option is to open resources using VS Code UI file dialogs.

@pospisilf do you guys have any examples on how to do it using native VSCode UI? or perhaps some helpers? would highly appreciate that

Hello @Arcticae
you can see description how to use dialogs in our docs - https://github.com/redhat-developer/vscode-extension-tester/wiki#using-dialogs

Here is an example how to use it eg. for opening file - https://github.com/redhat-developer/vscode-extension-tester/blob/main/tests/test-project/src/test/workbench/open.test.ts#L30
