Gopls test autocompletion issue

[vadimi]

Thank you for the bug report

• I am using the latest version of lsp-mode related packages.
• I checked FAQ and Troubleshooting sections
• You may also try reproduce the issue using clean environment using the following command: M-x lsp-start-plain

Bug description

gopls offers test method generation autocompletion by typing in func Tes. But for some reason after test method is generated the text used for method generation gets copied outside of the method declation, please see this video:

go_autocomplete.mov

Steps to reproduce

1. open any go test file (xxx_test.go)
2. type in func Tes to see the autocompletion popup
3. press Enter

Expected behavior

test method should get generated without copying text to the end of the method declaration

Which Language Server did you use?

lsp-go with gopls

OS

Hi, I have the same issue.

I restarted gopls with the -rpc.trace argument and can see the completion going to the server.

Request:

[Trace - 16:49:00.821 PM] Sending request 'textDocument/completion - (3947)'.
Params: {"textDocument":{"uri":"file:///home/viktor/tmp/complete/complete_test.go"},"position":{"line":2,"character":13},"context":{"triggerKind":1}}

Response:

[Trace - 16:49:00.821 PM] Received response 'textDocument/completion - (3947)' in 0ms.
Result: {"isIncomplete":true,"itemDefaults":{"editRange":{"start":{"line":0,"character":0},"end":{"line":0,"character":0}}},"items":[{"label":"TestSome(t *testing.T)","labelDetails":{},"kind":3,"documentation":"complete the parameter","preselect":true,"sortText":"00000","filterText":"TestSome(t *testing.T)","insertTextFormat":2,"textEdit":{"range":{"start":{"line":2,"character":5},"end":{"line":2,"character":5}},"newText":"TestSome(t *testing.T)"}}]}

If I understand LSP correctly then having start == end like in "textEdit":{"range":{"start":{"line":2,"character":5},"end":{"line":2,"character":5}} means the completion will just insert text.

So could this be a problem in gopls?
