Visual Studio Code Task Argument - go

I'm trying to create some tasks in Visual Studio Code to run all the tests in my go project.
I usually execute the tests on the command line using:
go test ./...
In Visual Studio Code my tasks.json looks like this:
{
"version": "0.1.0",
"command": "go",
"tasks": [
{
"taskName": "build",
"isBuildCommand": true
},
{
"taskName": "test",
"isTestCommand": true,
"args": ["./..."]
}
]
}
So Build works fine (CTRL + SHIFT + B)
But when I try to run the tests (CTRL + SHIFT + T) the following error occurs:
go: unknown subcommand "./..."
It seems to be omitting the "test" param, but when I comment out the args it runs go test fine.
Any ideas?

THIS MAY BE A BUG
VSCode Reverse Args and Task as of v0.8.0
This may be a bug that still persists in the newer versions. As of v0.9.1 I have not had a chance to test. Prior to 0.9.1 at least one hack worked by reversing the task and it's arg as in the following example:
{
"version": "0.1.0",
"command": "go",
"tasks": [
{
"taskName": "build",
"isBuildCommand": true
},
{
"taskName": "./...",
"isTestCommand": true,
"args": ["test"]
}
]
}
It's hard to believe that this has still persisted until v0.8.0 so there may be a preferred solution that I have not discovered.
Here is a link to a prior post that deals with a similar issue:

Compile two golang files into one executable and run in vscode

I have a go program with a main.go and a sub.go. When I run it under the debugger, main cannot see the function defined in sub. I tried creating a tasks.json but when I run it nothing happens.]
The MS documentaiton linked is for Node Package Manager and it doesn't state where the identifier for the task is placed in the configuration file
Here is my tasks.json:

This might be happening due to recent updates to VS Code Go extension.
First options is to fix it by running "Go: Install/Update Tools" command from the Command Palette (Linux/Windows: Ctrl+Shift+P, Mac: ⇧+⌘+P).
Then, mark dlv & dlv-dap from the menu, and hit ok to start install/update.
Delve’s native DAP implementation is under active development, so take advantage of the most recent features and bug fixes by using Delve built from its master branch. The Go extension maintains this newest version of Delve separately from the officially released version of dlv and installs it with the name dlv-dap.
Second option, is to use legacy debug adapter. More on this in the link below ...
Check out the full documentation at https://github.com/golang/vscode-go/blob/master/docs/debugging.md
You might have some luck switching the delveConfig to use legacy mode:
"go.delveConfig":{
"debugAdapter":"legacy"
}
My team and I recently began seeing the same issue after updating VSCode. There's a little more info on this setting here: https://go.googlesource.com/vscode-go/+/HEAD/docs/debugging.md#switching-to-legacy-debug-adapter, but I believe root cause (if this does indeed solve your issue) is going to be your version of Golang is not the version targeted by dlv-dap. Anything below Go version 1.15 needs to use legacy mode, and the latest version of the delve debugger happens to skip legacy mode by default now.
I also needed to kill VSCode before this change took effect. According to the dlv-dap docs, you can also force it into legacy mode by switching launch.json's mode to "remote", so there's likely a few (maybe better) ways to resolve this issue.
For macOS users:
brew install delve

Running vscode task that includes which fails

I have a task created that runs some unittests via bash_unit.
The bash unit script seems to fail based on its use of which.
If I replace:
CAT="$(which cat)"
and other which referances in bash unit to point to my local commands all runs great.
If I run bash)unit directly all good, but if i run it as a vscode task it fails.
I have simplified the task below to the minimum failure:
{
// See https://go.microsoft.com/fwlink/?LinkId=733558
// for the documentation about the tasks.json format
"version": "2.0.0",
"tasks": [
{
"label": "run which",
"type": "shell",
"command": "/usr/bin/which which",
"problemMatcher": [],
"group": "test",
}
]
}
This produces the following:
The terminal process "/bin/bash '-c', '/usr/bin/which which'" failed to launch (exit code: 1).
Any ideas what is happening?

Why aren't my Visual Studio Code task executing?

I am struggling with getting my Visual Studios code task to work. The problem is that it seems like the task/.bat file is not being executed.
VS Code task configuration:
{
// See https://go.microsoft.com/fwlink/?LinkId=733558
// for the documentation about the tasks.json format
"version": "2.0.0",
"tasks": [
{
"label": "My Label",
"type": "shell",
"windows": {
"command": "'c:\\Program Files (x86)\\path\\to\\the\\file.bat${file}'"
},
"presentation": {
"reveal": "always"
},
"group": {
"kind": "build",
"isDefault": true
}
}
]
}
For testing purposes the file.bat contains:
echo "------"
echo %1
echo "------"
The output in Visual Studio Code terminal is:
> Executing task in folder User: 'c:\\Program Files (x86)\\path\\to\\the\\file.bat c:\project\file.abc' <
c:\\Program Files (x86)\\path\\to\\the\\file.bat c:\project\file.abc
Terminal will be reused by tasks, press any key to close it.
I expected that the ${file} argument/value to printed in the console. The problem is that nothing is printed. It doesn't matter if I intentionally make syntax errors in the bat file. From VS Code it seems like the .bat file is not executed at all.
The shell being used is PowerShell
Configuration:
"terminal.integrated.shell.windows": "C:\\WINDOWS\\System32\\WindowsPowerShell\\v1.0\\powershell.exe"
Thank you in advance!

You just have a slight syntax error using double quotes and single quotes together.
Change to:
...
"windows": {
"command": "c:\\Program Files (x86)\\path\\to\\the\\file.bat ${file}"
}

Debug Electron using Visual Studio Code on Mac

Refer to this stackoverflow question:
I am trying to do the same but on Mac. I have the same as above,except instead of
"runtimeExecutable": "node_modules/electron-prebuilt/dist/electron.exe"
I have it as
"runtimeExecutable": "/usr/local/bin/electron"
Since F5 on mac is mapped to screen dimmer, I launched the app from command line as follows:
electron --debug-brk=5858 .
My program launched and ran without breaking.
So I modified keybindings.json like so:
[
{ "key": "shift+ctrl+f5", "command": "workbench.action.debug.play",
"when": "inDebugMode" },
{ "key": "shift+ctrl+f5", "command": "workbench.action.debug.start",
"when": "!inDebugMode" },
]
I tried launching the program by pressing shift+ctrl+f5 - I am still unable to debug my program.
I get the following error:
Error: Connection Failed
when I run node instead of electron, the debugger works fine when the the app is launched from command line
PLEASE HELP!
Thanks in advance
This is your launch.json. The important parts are runtimeExecutable and env. For VS Code 0.8.0, debugging only mostly works using electron 0.30.6.

Install 0.30.6 of electron-prebuilt in your project directory using npm install –-save-dev electron-prebuilt#0.30.6
