* @fileoverview
* @suppress {checkTypes} By default, JSCompile is not run on test files.
* However, you can modify |remoting_webapp_files.gypi| locally to include
* the test in the package to expedite local development. This suppress
* is here so that JSCompile won't complain.
*
* Provides basic functionality for JavaScript based browser test.
*
* To define a browser test, create a class under the browserTest namespace.
* You can pass arbitrary object literals to the browser test from the C++ test
* harness as the test data. Each browser test class should implement the run
* method.
* For example:
*
* browserTest.My_Test = function(myObjectLiteral) {};
* browserTest.My_Test.prototype.run() = function() { ... };
*
* The browser test is async in nature. It will keep running until
* browserTest.fail("My error message.") or browserTest.pass() is called.
*
* For example:
*
* browserTest.My_Test.prototype.run() = function() {
* window.setTimeout(function() {
* if (doSomething()) {
* browserTest.pass();
* } else {
* browserTest.fail('My error message.');
* }
* }, 1000);
* };
*
* You will then invoke the test in C++ by calling:
*
* RunJavaScriptTest(web_content, "My_Test", "{"
* "pin: 123123"
* "}");
