☑️ tests_from_xctestrun

Do you have multiple test targets referenced by your xctestrun file and need to know all the tests? Use this action to go through each test target, collect the tests, and return them to you in a simple and usable structure.

Example

require 'fastlane/actions/scan'

lane :split_tests do
  scan(
    build_for_testing: true,
    workspace: File.absolute_path('../AtomicBoy/AtomicBoy.xcworkspace'),
    scheme: 'AtomicBoy'
  )
  derived_data_path = Scan.config[:derived_data_path]
  xctestrun_file = Dir.glob("#{derived_data_path}/Build/Products/*.xctestrun").first
  tests = tests_from_xctestrun(xctestrun: xctestrun_file).values.flatten.shuffle
  slice_size = (tests.size/4.0).ceil
  tests.each_slice(slice_size).each_with_index do |inner_array, index|
    File.write("test_output/batch#{index}.txt", inner_array.join(','))
  end
end

lane :run_split_tests do |options|
  batch_file = File.join('test_output', "batch#{options[:batch_index]}.txt")
  only_testing = File.read(batch_file).split(',')
  multi_scan(
    workspace: File.absolute_path('../AtomicBoy/AtomicBoy.xcworkspace'),
    scheme: 'AtomicBoy',
    try_count: 3,
    fail_build: false,
    only_testing: only_testing
  )
end
