"debug this test" option from editor not parsing flags

[lfourky]

Describe the solution you'd like
I would like to be able to pass flags to the debugger when debugging from the editor.

Describe alternatives you've considered
I was able to run dlv and pass flags to it from the terminal, so I guess there must be a way to pass flags when using the "debug this test" from the editor, as well.

Example code that I would like to be able to debug from editor:

@lfourky Are you passing flag via args property in launch.json? You should have something like:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Launch",
            "type": "go",
            "request": "launch",
            "mode": "auto",
            "program": "${fileDirname}",
            "env": {},
            "args": ["-f=flag_value_placeholder"]
        }
    ]
}

I am able to pass flag value to tests and debug them from VSCode with this in place.

Seems this issue has already been filed: #2115

I have tried to add the flag to "args", yes. Since @BojanKomazec and I had a conversation outside of this, we've come to the conclusion that debugging the tests by using the F5 command or selecting Debug -> Start Debugging (F5) from the menu bar in VSCode works - the flags get parsed!

However, the issue still remains, when pressing the "debug test" option just above a specific test, the flags don't get parsed.

EDIT: Sorry, haven't seen the duplicate issue before. However, it's still ongoing, and I'm happy to provide any feedback if needed.

The flags provided in the debug configuration in the launch.json file do not get used by the debug test code lens that appears above individual tests.

But the ones that get passed to go.testFlags should definitely get used. Have you tried that?

[ramya-rao-a]

If you are specifically looking for args that should get passed, then #2115 is indeed tracking this case and we can close this issue

Thanks @ramya-rao-a for the go.testFlags hint. I can confirm that particular test is able to pick passed flags ONLY if run via run test code lens BUT NOT if run via debug test if settings.json contains the above mentioned property and looks like:

{
   ...
   "go.testFlags": ["-f=flag_value_placeholder"],
   ...
}

Thanks everyone. @ramya-rao-a I was not looking for args specifically, I just need a way to pass flags when debugging specific test functions. Will continue the discussion there, though!
