This looks like a pretty standard config – why can't this just be in
chromium_fyi.py?

+
+  api.chromium.compile(targets=['empty_fuzzer'])
+
+  config_kwargs = bot_config.get('chromium_config_kwargs', dict())
+  build_config = config_kwargs.get('BUILD_CONFIG', 'Release')
+  build_dir=api.path['slave_build'].join('src', 'out', build_config)
+
+  api.step('running empty_fuzzer', [api.path.join(build_dir, 'empty_fuzzer'),
+                                    '-runs=1'])

+def GenTests(api):
+  for test in api.chromium.gen_tests_for_builders(BUILDERS):
+    yield test
