 they take effect and build still passes.
 
 ### Add a new non gtest-based test
 Generally, look at [steps.py](https://code.google.com/p/chromium/codesearch#chromium/build/scripts/slave/recipe_modules/chromium_tests/steps.py)
-, and either use an existing class there, or add a new one. For example, look at
-the Android Tests (amp split) [recipe](https://code.google.com/p/chromium/codesearch#chromium/build/scripts/slave/recipe_modules/chromium_tests/chromium_fyi.py)
-, which uses a special step to talk to an external service:
-
-```
-'Android Tests (amp split)': {
-  ...
-  'tests': [
-    steps.AndroidInstrumentationTest('AndroidWebViewTest'),
-    steps.AndroidInstrumentationTest('ContentShellTest'),
-    steps.AMPGTestTest('android_webview_unittests',
-        device_name=['Nexus 5'], device_os=['4.4.2']),
-    steps.AMPGTestTest('base_unittests',
-        device_name=['Nexus 5'], device_os=['4.4.2'],
-        android_isolate_path='base/base_unittests.isolate'),
-    ...
-  ]

 ## Background
 Chromium tests are currently run on buildbot, and are organized by builders.
 A builder, in buildbot’s terminology, is a sequence of steps
 (typically, individual commands) executed by a slave, and controlled by
 the central master process.
 
 Since such tightly controlled system is hard to maintain at scale, and requires
 human attention and frequent downtimes for master restarts on every update,
 Chrome Infra introduced [recipes](https://chromium.googlesource.com/external/github.com/luci/recipes-py/+/master/doc/user_guide.md).

 Implements methods like `configure_build`, `prepare_checkout`, compile, etc.
 that take configuration parameters and actually run the steps.
 
 ### src/testing/buildbot/*.json: per-master configs: targets & tests
 
 Example config: [src/testing/buildbot/chromium.mac.json](https://code.google.com/p/chromium/codesearch#chromium/src/testing/buildbot/chromium.mac.json&sq=package:chromium)
 
 These configs live in the project repo, and define additional compile targets and specific tests to run on each builder.
