How to ignore files and folders in bashcov in GitLab-CI yaml?

[a-t-0]

Thank you for your work on this project! While trying to run Bashcov on a basic BATS testing repo in a .GitLab-CI.yml:

image: vergissberlin/alpine-development

stages:
  - build
  - deploy

test:
  stage: build
  image: ruby:slim
  before_script:
    - gem install bashcov
  script:
    # bashcov cannot run as root so here's a magic user
    - useradd -s /bin/bash user
    - su user -c "$(command -v bashcov) test"
  coverage: '/\(\d+\.\d+%\) covered/'
  artifacts:
    untracked: true

I receive the error:

bashcov: warning: encountered an error parsing Bash's output (error was: expected integer for LINENO, got ""). This can occur if your script or its path contains the sequence "010ae148-b419-4384-b227-69b97f25cdb6", or if your script unsets LINENO. Aborting early; coverage report will be incomplete.

So after scanning the tested repo I noticed the bats installation packages at: test/libs/bats/* contain the $lineno variable.

So I thought I would perhaps be able to circumvent this error by adding the test/libs/bats/* dir to the ignored folders when I run bashcov with:

bashcov bats test

However, after inspecting the documentation:

bashcov --help
Usage: bashcov [options] [--] <command> [options]
Examples:
    bashcov ./script.sh
    bashcov --skip-uncovered ./script.sh
    bashcov -- ./script.sh --some --flags
    bashcov --skip-uncovered -- ./script.sh --some --flags

Specific options:
    -s, --skip-uncovered             Do not report uncovered files
    -m, --mute                       Do not print script output
        --bash-path PATH             Path to Bash executable
        --root PATH                  Project root directory
        --command-name NAME          Value to use as SimpleCov.command_name

Common options:
    -h, --help                       Show this message
        --version                    Show version

I did not find an option to ignore certain folders. Hence, I would like to ask:

How can I specify ignored folders and files when running bashcov bats test?

The --exclude/--ignore option is supported through a SimpleCov configuration file. In the root directory of one's own project, one can add a .simplecov file with content:

SimpleCov.start do
  minimum_coverage 15
  add_filter "test/libs"
  add_filter "/.git/"
end

And that ensures the coverage report and result ignore those test/libs/ and .git/ directories.
