openTextDocument after opening a folder

[mdt123]

I am trying to write unit tests that open a specific folder as a workspace, and then open a specific file and show it in the editor.

I tried using the vscode.openFolder command to open the folder which worked, but I cant seem to be able to open files after that's executed.

        vscode.commands.executeCommand("vscode.openFolder", wsUri);
        
        const document = await vscode.workspace.openTextDocument(fileUri);
        const editor = await vscode.window.showTextDocument(document);

also tried to open the file in then

          vscode.commands.executeCommand("vscode.openFolder", wsUri).then(async () => {

          const document = await vscode.workspace.openTextDocument(fileUri);
          const editor = await vscode.window.showTextDocument(document);
        });

The behavior is that the folder opens but after that the document does not.
If I try to open the document without opening the folder, it opens. But I need to open the folder first.

The described behavior is how it is expected to work. If you disagree, please explain what is expected and what is not in more detail. See also our issue reporting guidelines.

Happy Coding!

Requiring a window reload when opening a folder is unfortunately a limitation we cannot lift easily. You cannot write a test today that opens a folder first and then executes code, also because the extension host will restart (related: #69335)
