bluepillar plugin

Getting Started

This project is a fastlane plugin to run XCUI Tests in parallel using Linkedin's Bluepill tool. To get started with fastlane-plugin-bluepillar, add it to your project by running:

fastlane add_plugin bluepillar

Pre-requisite

Bluepill homebrew package doesn't work well as it's lacking bp binary. We have to manually download bluepill and bp binaries from the Bluepill releases page on Github and put in PATH. This plugin expect it inside /usr/local/bin/ where all the other binaries live, so that we have /usr/local/bin/bluepill and /usr/local/bin/bp binaries in place.

Fastlane Setup

We can setup Fastlane using some BluePill optins and Derived data.

BluePill Options

There are so many options available for the Bluepill but we just need few of them to get going and keep other options as default. This plugin provides basic 7 options as follows

• app : PATH to your application. This is usually in the derived data /Products/Debug-iphonesimulator/YOUR_APP.app

• runner_app_path : PATH to UI Test runner app. This is usually in derived data /Products/Debug-iphonesimulator\YOUR_UITEST_SCHEME-Runner.app If you have a space in the Scheme name then you have to amend it with backslash in your path.

• scheme_path : This is path to your scheme. This is usually in the YOUR_PROJECT.xcodeproj/xcshareddata/xcschemes/YOUR_SCHEME.xcscheme

• output_dir : This is a directory where Bluepill will generate reports.

• num_sims : Number of simulators to be launched.

• runtime : The iOS version we want to run test against. Note we have to pass it as nested string like this '"iOS 10.3"'

• device: The simulator to be used. We have to pass it as 'iPad Air' or 'iPhone 6'

Generate Derived Data for Bluepill

It's good idea to generate derived data in the project itself using build for testing option. You can do that using Fastlane scan like this

scan(
    scheme: YOUR_SCHEME,
    build_for_testing: true,
    derived_data_path: "./bluepill",
    buildlog_path: "./bluepill/logs/"
  )

This will generate derived data inside bluepill directory.

Configure Fastfile

Now that, all the Bluepill options are in place and we have generated derived data, we can configure lane in our Fastfile like this:

lane :test do
    app: 'bluepill/Build/Products/Debug-iphonesimulator/Bluepillar.app',
    runner_app_path: 'bluepill/Build/Products/Debug-iphonesimulator/BluepillarUITests-Runner.app',
    scheme_path: 'Bluepillar.xcodeproj/xcshareddata/xcschemes/Bluepillar.xcscheme',
    output_dir: 'bluepill_output/',
    num_sims: '3',
    runtime: '"iOS 10.3"',
    device: 'iPad Air'
end

Now that we can run test using fastlane like this :

       $ fastlane test

About bluepillar

Run XCUITests in Parallel using Bluepill. Bluepill is a tool from LinkedIn to run XCUI tests in the parallel.

Example

There is sample example project available on Github Bluepillar-Demo. Just clone it, replace the path to derived data and run

         $ git clone git@github.com:Shashikant86/Bluepillar-Demo.git
         $ bundle install
         $ bundle exec fastlane test

You can see sample report in the sample_bluepill_output directory.

Run tests for this plugin
