SPLIT

Parallelizing directive

Webapp.io provides a utility to run tests in parallel - SPLIT 5 duplicates the entire VM 5 times at the point it executes. In practice this means that you can run tests in parallel without worrying about race conditions causing flaky tests.

Rails: knapsack

See knapsack pro

Install the gem
Run KNAPSACK_GENERATE_REPORT=true bundle exec rspec spec on your local computer
git add knapsack_rspec_report.json && git commit -m 'knapsack' && git push origin master

Your Layerfile will look something like this:

Layerfile

# install ruby, bundle install, etc

COPY . .
SPLIT 5
ENV CI_NODE_TOTAL=$SPLIT_NUM CI_NODE_INDEX=$SPLIT
RUN bundle exec knapsack:rspec

Go: custom test runner

See this file for an example parallel test runner for go. The Layerfile from that example:

Layerfile

FROM ../base/Layerfile

COPY . .
SPLIT 5
RUN ./parallel-go-test.sh

The Layerfile Cache RUN REPEATABLE
