gcov2lcov-action's Introduction

gcov2lcov-action

Convert golang coverage files to lcov format. Works nicely with the coveralls github action and uses gcov2lcov under the hood.

Inputs

`infile`

Optional Name of the go coverage file. Default coverage.out.

`outfile`

Optional Name of the lcov file to write. Default coverage.lcov.

`version`

Optional Name of the specific gcov2lcov program version. Default latest.

`working-directory`

Optional Name of directory where gcov2lcov is run. Defaults to $GITHUB_WORKSPACE.

Outputs

No outputs.

Example usage

uses: jandelgado/gcov2lcov-action@v1
with:
  infile: coverage.out        # optional, default filename is `coverage.out`
  outfile: coverage.lcov      # optional, default filename is `coverage.lcov`
  version: v1.0.4             # optional, use specific `gcov2lcov` release version
  working-directory: testdata # optional, change working directory

Full example

coverage:
  runs-on: ubuntu-latest
  steps:
    - name: Install Go
      if: success()
      uses: actions/setup-go@v3
      with:
        go-version: 1.18
    - name: Checkout code
      uses: actions/checkout@v2
    - name: Calc coverage
      run: go test -v -covermode=count -coverprofile=coverage.out
    - name: Convert coverage to lcov
      uses: jandelgado/gcov2lcov-action@v1
    - name: Coveralls
      uses: coverallsapp/[email protected]
      with:
        github-token: ${{ secrets.github_token }}
        path-to-lcov: coverage.lcov

Is it because runner doesn't have Go v1.13 installed anymore?

Why not use precompiled binary?

Bad download link for specific versions

When a gcov2lcov version is specified (i.e. v1.0.4), the download link is created as:

https://github.com/jandelgado/gcov2lcov/releases/v1.0.4/download/gcov2lcov-linux-amd64.tar.gz

But it should be:

https://github.com/jandelgado/gcov2lcov/releases/download/v1.0.4/gcov2lcov-linux-amd64.tar.gz

It seems that for latest, it works as:

https://github.com/jandelgado/gcov2lcov/releases/latest/download/gcov2lcov-linux-amd64.tar.gz

But not for specific versions.

I don't think -coverpkg=./... is handled well.

codecov: 82%
coveralls: 48%
https://github.com/arvenil/kata

go test -coverpkg=./... -coverprofile=coverage.txt -covermode=atomic ./...

Note -coverpkg=./....
This results in below file (I cut it only to show line 14 of templates.go file):

$ cat coverage.txt | grep templates.go:14
github.com/arvenil/kata/format/templates/templates.go:14.37,19.17 5 0
github.com/arvenil/kata/format/templates/templates.go:14.37,19.17 5 0
github.com/arvenil/kata/format/templates/templates.go:14.37,19.17 5 1
github.com/arvenil/kata/format/templates/templates.go:14.37,19.17 5 0
github.com/arvenil/kata/format/templates/templates.go:14.37,19.17 5 0
github.com/arvenil/kata/format/templates/templates.go:14.37,19.17 5 0

As you may see, for example, line 14 is visible there several times with different count.
This tool converts it to:

DA:14,0
DA:14,0
DA:14,1
DA:14,0
DA:14,0
DA:14,0

And then coveralls doesn't seem to handle it and shows ZERO coverage when there was exactly one pass. Maybe this tool should sum such entries, and as so coveralls would show correct value, or maybe it's a bug worth reporting to coveralls?
