# Rails app with knapsack

[![Circle CI](https://circleci.com/gh/KnapsackPro/rails-app-with-knapsack.svg)](https://circleci.com/gh/KnapsackPro/rails-app-with-knapsack)

This is example Ruby on Rails app with knapsack gem. Knapsack splits tests across CI nodes and makes sure that tests will run comparable time on each node.

__You can read more about free [knapsack gem here](https://github.com/ArturT/knapsack). You will find there info how to set up your test suite and how to do it on your favorite CI server.__

## How to load knapsack rake tasks

See [Rakefile](Rakefile).

## Parallel rspec test suite with knapsack

### How to set up knapsack

See [spec/spec_helper.rb](spec/spec_helper.rb)

### Step 1

First generate only once a report `knapsack_rspec_report.json` on your CI with command:

    $ KNAPSACK_GENERATE_REPORT=true bundle exec rspec spec

Add the report into your repository and commit.

### Step 2

You can use below command on CI to run tests:

    # Run this on first CI server

    $ CI_NODE_TOTAL=2 CI_NODE_INDEX=0 bundle exec rake knapsack:rspec

    # Run this on second CI server

    $ CI_NODE_TOTAL=2 CI_NODE_INDEX=1 bundle exec rake knapsack:rspec

See [.circleci/config.yml](.circleci/config.yml) to see how we set up CircleCI.

## Parallel cucumber test suite with knapsack

### How to set up knapsack

See [features/support/knapsack.rb](features/support/knapsack.rb)

### Step 1

First generate only once a report `knapsack_cucumber_report.json` on your CI with command:

    $ KNAPSACK_GENERATE_REPORT=true bundle exec cucumber features

Add the report into your repository and commit.

### Step 2

You can use below command on CI to run tests:

    # Run this on first CI server

    $ CI_NODE_TOTAL=2 CI_NODE_INDEX=0 bundle exec rake knapsack:cucumber

    # Run this on second CI server

    $ CI_NODE_TOTAL=2 CI_NODE_INDEX=1 bundle exec rake knapsack:cucumber

See [.circleci/config.yml](.circleci/config.yml) to see how we set up CircleCI.

## Parallel minitest test suite with knapsack

### How to set up knapsack

See [test/test_helper.rb](test/test_helper.rb)

### Step 1

First generate only once a report `knapsack_minitest_report.json` on your CI with command:

    $ KNAPSACK_GENERATE_REPORT=true bundle exec rake test

Add the report into your repository and commit.

### Step 2

You can use below command on CI to run tests:

    # Run this on first CI server

    $ CI_NODE_TOTAL=2 CI_NODE_INDEX=0 bundle exec rake knapsack:minitest

    # Run this on second CI server

    $ CI_NODE_TOTAL=2 CI_NODE_INDEX=1 bundle exec rake knapsack:minitest

See [.circleci/config.yml](.circleci/config.yml) to see how we set up CircleCI.

## Parallel spinach test suite with knapsack

### How to set up knapsack

See [spinach_features/support/env.rb](spinach_features/support/env.rb)

### Step 1

First generate only once a report `knapsack_spinach_report.json` on your CI with command:

    $ KNAPSACK_GENERATE_REPORT=true bundle exec spinach -f spinach_features

Add the report into your repository and commit.

### Step 2

You can use below command on CI to run tests:

    # Run this on first CI server

    $ CI_NODE_TOTAL=2 CI_NODE_INDEX=0 KNAPSACK_TEST_FILE_PATTERN="spinach_features/**{,/*/**}/*.feature" bundle exec rake "knapsack:spinach[-f spinach_features]"

    # Run this on second CI server

    $ CI_NODE_TOTAL=2 CI_NODE_INDEX=1 KNAPSACK_TEST_FILE_PATTERN="spinach_features/**{,/*/**}/*.feature" bundle exec rake "knapsack:spinach[-f spinach_features]"
