Using Knapsack Pro with CircleCI

Collect metadata in Queue Mode

You may want to collect metadata in CircleCI. For example, to collect junit reports of your RSpec runs you would:

• Configure the junit formatter for RSpec
• Copy the report to the $CIRCLE_TEST_REPORTS directory as shown below

RSpec

spec_helper.rb or rails_helper.rb

# `TMP_REPORT` must be the same path as `--out`
# `TMP_REPORT` must be a full path (no `~`)
TMP_REPORT = "tmp/tmp_rspec_#{ENV['KNAPSACK_PRO_CI_NODE_INDEX']}.xml"
FINAL_REPORT = "tmp/final_rspec_#{ENV['KNAPSACK_PRO_CI_NODE_INDEX']}.xml"

KnapsackPro::Hooks::Queue.after_subset_queue do |queue_id, subset_queue_id|
  if File.exist?(TMP_REPORT)
    FileUtils.mv(TMP_REPORT, FINAL_REPORT)
  end
end

KnapsackPro::Hooks::Queue.after_queue do |queue_id|
  if File.exist?(FINAL_REPORT) && ENV['CIRCLE_TEST_REPORTS']
    FileUtils.cp(FINAL_REPORT, "#{ENV['CIRCLE_TEST_REPORTS']}/rspec.xml")
  end
end

CircleCI

.circleci/config.yml

- run:
    name: RSpec with Knapsack Pro in Queue Mode
    command: |
      export CIRCLE_TEST_REPORTS=/tmp/test-results
      mkdir $CIRCLE_TEST_REPORTS
      bundle exec rake "knapsack_pro:queue:rspec[--format documentation --format RspecJunitFormatter --out tmp/rspec.xml]"

- store_test_results:
    path: /tmp/test-results

- store_artifacts:
    path: /tmp/test-results
    destination: test-results

You can find a complete CircleCI configuration in RSpec testing parallel jobs with CircleCI and JUnit XML report.
