// Copyright 2014 The Flutter Authors. All rights reserved.
// Use of this source code is governed by a BSD-style license that can be
// found in the LICENSE file.
// Runs the tests for the flutter/flutter repository.
//
//
// By default, test output is filtered and only errors are shown. (If a
// particular test takes longer than _quietTimeout in utils.dart, the output is
// shown then also, in case something has hung.)
//
// --verbose stops the output cleanup and just outputs everything verbatim.
//
//
// By default, errors are non-fatal; all tests are executed and the output
// ends with a summary of the errors that were detected.
//
// Exit code is 1 if there was an error.
//
// --abort-on-error causes the script to exit immediately when hitting an error.
//
//
// By default, all tests are run. However, the tests support being split by
// shard and subshard. (Inspect the code to see what shards and subshards are
// supported.)
//
// If the CIRRUS_TASK_NAME environment variable exists, it is used to determine
// the shard and sub-shard, by parsing it in the form shard-subshard-platform,
// ignoring the platform.
//
// For local testing you can just set the SHARD and SUBSHARD environment
// variables. For example, to run all the framework tests you can just set
// SHARD=framework_tests. Some shards support named subshards, like
// SHARD=framework_tests SUBSHARD=widgets. Others support arbitrary numbered
// subsharding, like SHARD=build_tests SUBSHARD=1_2 (where 1_2 means "one of
// two" as in run the first half of the tests).
//
// So for example to run specifically the third subshard of the Web tests you
// would set SHARD=web_tests SUBSHARD=2 (it's zero-based).
//
// By default, where supported, tests within a shard are executed in a random
// order to (eventually) catch inter-test dependencies.
//
// --test-randomize-ordering-seed=<n> sets the shuffle seed for reproducing runs.
//
//
// All other arguments are treated as arguments to pass to the flutter tool when
// running tests.
