This: - Speeds up local test runs (no coverage overhead) - Avoids coverage file conflicts when running parallel tests locally - Allows parallel test execution without coverage merging complexity Coverage is still enabled in CI by setting COVERAGE=true in the workflow. Also adds proper parallel test support for coverage merging when TEST_ENV_NUMBER is set (by parallel_tests gem) or CI_NODE_INDEX (for GitHub Actions matrix strategy). --- spec/spec_helper.rb | 74 +++++++++++++++++++++++---------------------- 1 file changed, 38 insertions(+), 36 deletions(-) diff --git a/spec/spec_helper.rb b/spec/spec_helper.rb index 3ca44fcb8..ca4b95fab 100644 --- a/spec/spec_helper.rb +++ b/spec/spec_helper.rb @@ -1,47 +1,49 @@ -require 'simplecov' -require 'simplecov-lcov' +require 'simplecov' if ENV['COVERAGE'] == 'true' +require 'simplecov-lcov' if ENV['COVERAGE'] == 'true' require 'shoulda/matchers' require 'webmock/rspec' -# Fix incompatibility of simplecov-lcov with older versions of simplecov that are not expresses in its gemspec. -# https://github.com/fortissimo1997/simplecov-lcov/pull/25 +if ENV['COVERAGE'] == 'true' + # Fix incompatibility of simplecov-lcov with older versions of simplecov that are not expresses in its gemspec. + # https://github.com/fortissimo1997/simplecov-lcov/pull/25 -if !SimpleCov.respond_to?(:branch_coverage) - module SimpleCov - def self.branch_coverage? - false + if !SimpleCov.respond_to?(:branch_coverage) + module SimpleCov + def self.branch_coverage? + false + end end end -end -SimpleCov::Formatter::LcovFormatter.config do |c| - c.report_with_single_file = true - c.single_report_path = 'coverage/lcov.info' -end + SimpleCov::Formatter::LcovFormatter.config do |c| + c.report_with_single_file = true + c.single_report_path = 'coverage/lcov.info' + end -SimpleCov.formatters = SimpleCov::Formatter::MultiFormatter.new( - [ - SimpleCov::Formatter::HTMLFormatter, - SimpleCov::Formatter::LcovFormatter, - ] -) - -SimpleCov.start do - add_filter 'spec/' - - # Support parallel test execution - # In CI: Use CI_NODE_INDEX (0, 1, 2, 3) set by GitHub Actions matrix - # Locally: Use TEST_ENV_NUMBER ('', '2', '3', '4') set by parallel_tests - if ENV['CI_NODE_INDEX'] - command_name "RSpec-#{ENV['CI_NODE_INDEX']}" - use_merging true - merge_timeout 3600 - elsif ENV.key?('TEST_ENV_NUMBER') - # TEST_ENV_NUMBER is '' for first process, '2', '3', etc. for others - suffix = ENV['TEST_ENV_NUMBER'].empty? ?
