// This file provides reliablity test which runs under UI test framework. The
// test is intended to run within QEMU environment.
//
// Usage 1: reliability_test
// Upon invocation, it visits a hard coded list of sample URLs. This is mainly
// used by buildbot, to verify reliability_test itself runs ok.
//
// Usage 2: reliability_test --site=url --startpage=start --endpage=end [...]
// Upon invocation, it visits a list of URLs constructed as
// "http://url/page?id=k". (start <= k <= end).
//
// Usage 3: reliability_test --list=file --startline=start --endline=end [...]
// Upon invocation, it visits each of the URLs on line numbers between start
// and end, inclusive, stored in the input file. The line number starts from 1.
//
// If both "--site" and "--list" are provided, the "--site" set of arguments
// are ignored.
//
// Optional Switches:
// --iterations=num: goes through the list of URLs constructed in usage 2 or 3
//                   num times.
// --continuousload: continuously visits the list of URLs without restarting
//                    browser for each page load.
// --memoryusage: prints out memory usage when visiting each page.
// --endurl=url: visits the specified url in the end.
// --logfile=filepath: saves the visit log to the specified path.
// --timeout=millisecond: time out as specified in millisecond during each
//                        page load.
// --nopagedown: won't simulate page down key presses after page load.
// --noclearprofile: do not clear profile dir before firing up each time.
// --savedebuglog: save Chrome, V8, and test debug log for each page loaded.
