How to use vimspector with vim test

You can use the plugin vim-test to start your vimspector session.

Example using Node.js with Jest

Your debug adapter (using ${TestName} as an input variable and a globally-installed jest module):

{
  "configurations": {
    "jest": {
      "adapter": "vscode-node",
      "breakpoints": {
        "exception": {
          "all": "N",
          "uncaught": "N"
        }
      },
      "configuration": {
        "request": "launch",
        "name": "Debug Jest Test",
        "type": "node",
        "runtimeArgs": [
          "--inspect-brk",
          "/usr/local/bin/jest",
          "--no-coverage",
          "-t",
          "'${TestName}'",
          "--",
          "${file}"
        ],
        "console": "integratedTerminal",
        "skipFiles": ["<node_internals>/**/*.js"],
        "internalConsoleOptions": "neverOpen",
        "port": 9229
      }
    }
  }
}

Then you can add a test strategy in your vim configuration:

function! JestStrategy(cmd)
  let testName = matchlist(a:cmd, '\v -t ''(.*)''')[1]
  call vimspector#LaunchWithSettings( #{ configuration: 'jest', TestName: testName } )
endfunction

let g:test#custom_strategies = {'jest': function('JestStrategy')}

Now call :TestNearest -strategy=jest to debug your test.
