"Failed to decode JSON line" and "Test(s) not associated (not found/executed)"

[santiagorendong]

Not entirely sure if there's something missing on my end or if this is a bug, but I get a WARN log saying:

And also the warning:

Test(s) not associated (not found/executed): {... list of paths to the test}

I have the following structure:

arraystring
|-- length_of_last_word.go
|-- length_of_last_word_test.go

And the following tests:

package arraystring

import "testing"

func TestLengthOfLastWord(t *testing.T) {
	tests := []struct {
		name  string
		input string
		want  int
	}{
		{
			name:  "single word",
			input: "onomatopoeia",
			want:  12,
		},
		{
			name:  "multiple words",
			input: "luffy is still joyboy",
			want:  6,
		},
		{
			name:  "excess whitespace",
			input: "   fly me   to   the moon  ",
			want:  4,
		},
	}

	for _, tc := range tests {
		t.Run(tc.name, func(t *testing.T) {
			got := lengthOfLastWord(tc.input)
			if got != tc.want {
				t.Logf("got %d, wanted  %d", got, tc.want)
				t.Fail()
			}
		})
	}
}

My system:

• Windows 10 Pro 22H2
• NVIM 0.10.0
• Windows Terminal + PowerShell 7
• Go 1.22.1 windows/amd64

return {
  {
    "nvim-neotest/neotest",
    dependencies = {
      "nvim-neotest/nvim-nio",
      "nvim-lua/plenary.nvim",

      "nvim-treesitter/nvim-treesitter",
      
      "fredrikaverpil/neotest-golang",
    },
    config = function()
      local neotest = require("neotest")

      neotest.setup({
        adapters = {
          require("neotest-golang"),
        }
      })
    end,
  },
}

[fredrikaverpil]

I don't see anything wrong with your config. Since the adapter is definitively running I think this is very likely related to you being on Windows, as I've not tested the adapter at all on that platform.

I believe this particular issue comes from string replacements and regex in process.lua which needs to be updated to also support backslashes instead of only supporting forward slashes.

I'll have a look at this and we can track this as bug/issue #147 which is also related to supporting backslashes.

[fredrikaverpil]

I will close this, as it is closely related to #147, and the solution in PR #149.
