[Bug] Unable to select a launch target from a workspace file when .vscode/launch.json exists

[arghness]

Brief Issue Summary

If I have a "launch {}" section in my workspace file, and a .vscode/launch.json file, the "Run and Debug" tab lists all the launch targets from both sources in the pulldown.

However, if I try to debug a ctest target from the "Testing" tab, when it provides a pulldown to select a target, it shows duplicate targets from .vscode/launch.json. If I remove .vscode/launch.json it will show targets from the workspace file.

This also applies to the new setting "cmake.ctest.debugLaunchTarget", It won't allow me to use a target from the workspace file, if .vscode/launch.json is present.

Workspace showing the issue (please open the workspace file, not the folder): ctest_issue.zip

Run and debug tab:

Pulldown after pressing "Debug Test" button on "test1":

This shows the targets from launch.json twice, but says 2 of them are in the workspace, from the path underneath. If I try to select one from the workspace, it actually selects one from launch.json.

Hi @arghness, thanks for reporting issue here!
We can reproduce this issue on VS Code 1.104.3 + CMake tools 1.21.36 version.
Repro Steps:

1. Download the attached project (ctest_issue.zip) and open it with "Open Workspace from File".
2. Press F1, run command "CMake: Configure".
3. Open Testing, click on "Debug Test", observe the result.
4. Choose targets and observe the results.

Details please see following video:

I'm not familiar with the VSCode extension API, but I did a little investigation.

The issue seems to be in src/ctest.ts lines 1163 and 1167:

        const launchConfig = vscode.workspace.getConfiguration(
            'launch',
            workspaceFolder.uri
        );
        const workspaceLaunchConfig = vscode.workspace.workspaceFile ? vscode.workspace.getConfiguration(
            'launch',
            vscode.workspace.workspaceFile
        ) : undefined;

The "scope" parameter for vscode.workspace.getConfiguration doesn't seem to do what's expected here.

In the scenario from the ctest_issue.zip in the original post, if I remove "vscode.workspace.workspaceFIle" from the second call to vscode.workspace.getConfiguration, it will give the correct 4 launch configurations (2 from the first call, 2 from the second).

However, if I then remove .vscode/launch.json , the first call to vscode.workspace.getConfiguration also returns the 2 launch configurations from the workspace file, so we end up with the workspace launch targets being duplicated in the pulldown.

Thank you for the additional information.
