• I have updated to the latest version of Neotest.
• I have updated to the latest version of neotest-golang.

Describe the problem

Hello, I'm currently using neotest-golang to run and debug my tests, but I'm having some issues with debugging tests that include build flags.
I've tried passing the build_flags through the dap_go_opts option, but it doesn't seem to have any effect. It seems like the dap-go.debug_test() method is not being executed when a test file includes a build flag.
Every time I try to run a test with a build flag, I receive the following error message:

Error on launch: Failed to launch: Could not launch process: Not an executable file. 

Could you please help me understand what might be causing this issue and how I can resolve it? I'd really appreciate your assistance in this matter.

Hey @oleynikandrey I actually think this might be a bug. I opened #178 and it would be great if you can try that out. You can just add branch to your config:

return {
  {
    "fredrikaverpil/neotest-golang",
    branch = "dap-build-flags",
  }
}

If this doesn't help , I think we need to do some debug logging (details in the README).

Thank you for resolving the issue. It is working now.

That's really great to hear. Thanks for reporting this.

I merged the fix into main.
