test_center plugin 🎯

Have you ever spent too much time trying to fix fragile tests only to give up with nothing real to show? Use the fastlane actions from test_center to remove the pain around your tests, so that you can focus on what makes 💰: features that customers love 😍.

For those of you new to fastlane, I recommend that you read my article Rescue Your Mobile Builds from Madness Using Fastlane.

Features

This plugin makes testing your iOS app easier by providing you actions that give you greater control over everything related to testing your app.

multi_scan began when I created an action to only re-run the failed tests in order to determine if they were truly failing, or if they were failing randomly due to a fragile infrastructure. This action morphed into an entire plugin with many actions in the testing category.

This fastlane plugin includes the following actions:

read the documentation on each action by clicking on the action name

Action	Description	Supported Platforms
`multi_scan`	supports everthing that `scan` (also known as `run_tests`) does, and also supports: - dividing your tests evenly into batches and run each batch on its own Simulator in parallel to reduce the time to test - re-running tests that may be failing due to a fragile test environment - splitting tests into batches when a huge number of tests overwhelm the Simulator - performing an action after a block of tests have been run	ios, mac
`suppress_tests_from_junit`	suppress tests in an Xcode Scheme using those in a Junit test report	ios, mac
`suppress_tests`	suppress tests in an Xcode Scheme	ios, mac
`suppressed_tests`	returns a list of the suppressed tests in your Xcode Project or Scheme	ios, mac
`test_options_from_testplan`	returns the tests and test code coverage configuration for a given testplan	ios, mac
`testplans_from_scheme`	returns the testplans that an Xcode Scheme references	ios, mac
`tests_from_junit`	returns the passing and failing tests in a Junit test report	ios, mac
`tests_from_xcresult`	returns the passing and failing tests in a xcresult bundle	ios, mac
`tests_from_xctestrun`	returns a list of tests for each test target in a `xctestrun` file	ios, mac
`collate_junit_reports`	combines multiple Junit test reports into one report	ios, mac
`collate_html_reports`	combines multiple HTML test reports into one report	ios, mac
`collate_json_reports`	combines multiple json test reports into one report	ios, mac
`collate_test_result_bundles`	combines multiple test_result bundles into one test_result bundle	ios, mac
`collate_xcresults`	combines multiple xcresult bundles into one xcresult bundle	ios, mac

Installation

This project is a fastlane plugin. To get started with fastlane-plugin-test_center, add it to your project by running:

fastlane add_plugin test_center

Usage

Click the name of each action above and review the documentation to learn how to use each action.

The most popular action in the test_center plugin is multi_scan, and if you run your tests in parallel with multiple retries, they will finish faster and only the truly failing tests will be reported as failing:

multi_scan(
  project: File.absolute_path('../AtomicBoy/AtomicBoy.xcodeproj'),
  scheme: 'AtomicBoy',
  try_count: 3, # retry _failing_ tests up to three times^1.
  fail_build: false,
  parallel_testrun_count: 4 # run subsets of your tests on parallel simulators^2
)
# [1] The ones that pass on a retry probably failed due to test interactions or test infrastructure
# [2] splits all your tests into 4 smaller batches and runs each batch on its own sim in parallel for faster completion!
