Using lcov with genhtml

You can combine the lcov exporter, with the genhtml command in order to generate an HTML coverage report for your complete workspace codebase.

From the workspace Makefile:

.PHONY: coverage
coverage: ## Generates coverage report
  mix workspace.run -t test -- --cover
  mix workspace.test.coverage
  genhtml artifacts/coverage/lcoverage.lcov -o artifacts/coverage --prefic ${PWD}

Options

The following options are supported:

• :filename - the .lcov filename, defaults to coverage.lcov
• :output_path - the output path, defaults to cover under the current directory

Usage

In order to enable LCOV coverage exporter you can add the following to your workspace's :test_coverage, :exporters config:

test_coverage: [
  exporters: [
    lcov: fn workspace, coverage_stats ->
      Workspace.Coverage.LCOV.export(workspace, coverage_stats,
        output_path: "artifacts/coverage"
      )
    end
  ]
