In order to get useful and realistic feedback from real users, some software companies deliver pre-release software (a beta or beta trial) to a select number of users to try it out and report bugs, make suggestions, or just give significant customers clear evidence of the state of the product and dispel rumors of vaporware.
In terms of the software development, beta is usually the stage where all major feature implementation should be finished and the software is in the phase of bug fixing, refinement and stabilization before declaring a Final or Release candidate (sometimes called "Gold" as well). Sometimes major changes occur in this stage, but usually only in response to feedback during a beta trial.
Beta, of course, comes after the Alpha stage where major feature implementation usually occurs, is known to be unstable, and not generally fit for anything more than internal trial of carefully selected users. The stage before Alpha some call "Pre-Alpha", "Proof of Concept", or "Prototype".
These stages are semi-formal within the software industry, so "your results may vary".
What Blizzard says about betas
Betas are not guaranteed to work for all | 2012-04-14 15:03 |Kaltonis
"A real beta rarely works, and when it does, it doesn't work well."
Unlike a lot of companies who invite players into "betas" that are little more than game demos of stable preview builds, Blizzard brings in players to an ever-changing process where our programmers are constantly making changes to the "guts" of the game.
What does that mean for you?
Betas are not guaranteed to work for individual players, ever. It's entirely possible that some users will receive a beta invite, only to find that they're never actually able to play it. This is simply the nature of a true beta. While we'd prefer everyone to be able to have a little fun while helping us test the content and servers, the purpose of the beta is to prepare Mists of Pandaria for launch, not to provide a gaming experience for beta testers.
Additionally, because of how quickly conditions change in a beta, it is extremely difficult to provide technical support that is specific to Mists of Pandaria issues. If it seems like the help you receive is very general in nature (update drivers, uninstall security programs, etc.) it's because the tech support staff does not have more specific information on the issue you are dealing with. Please remember that Blizzard is under no obligation to provide support for a product in beta, although we do try when possible.
All of that being said, we do hope that most of you will enjoy your sneak-peek into the game design process. Just be advised that trying to play a beta like it's a finished game will likely result in a very frustrating experience. Take care out there!
The terms "closed beta" and "open beta" are also used when referring to the actual beta trial period of testing. The usage of these terms is not consistent, but the following definitions can be used as a guideline:
Closed beta - Only a selected group of users are invited to the beta trial with varying criteria. Some closed betas are very restrictive and others are tied to a promotion or some other easily obtainable criteria (like purchasing the Annual Pass). Invitation, of course, is not guaranteed.
Open beta - This is basically a trial which is usually only restricted by the need to download the software and go through some sort of registration process. Users may be required to meet some minimum hardware and software requirements, but usually nothing needs to be paid for or membership in a special group needed.
Stuff with names like "something needs a name" or "TBD", etc.
Login problems during announced or known server maintenance periods (usually announced on official forums, launcher news, Twitter, etc.).
Problems widely reported in official status forums and Warcraft news sites (unless it is reported as hard to repro and you have a consistent way to repro the problem).
A closed beta test period was announced on March 20, 2012 with invites going to Annual Pass holders, press, fansites, friends and family, and opt-in beta testers.[3]MMO Champion may have gotten access soon after the opt-in announcement[4] and an official announcement of the start of the Beta was released late March 21st, 2012.[5]
A 64-bit client for Windows (WoW-64.exe) was quietly downloaded with build 15640 of the Beta that was noticed by some users and clarified by an MVP.[7] The key difference between this test release and previous Live and PTR releases was that it was installed with Lancher and did not have to be installed manually. MVPBluspacecow predicted correctly that a 64-bit Mac OS X client (World of Warcraft-64.app) would be available with build 15657.[8]
This section concerns content that is out-of-date. Reason: Need screenshots from new login screen, build 15726.
The Mists of Pandaria beta servers use the same authentication portal as the PTR servers so you may be given the unexpected choice to login as either "wow1" or "wow2" accounts. If you see this choice, select "wow2" assuming you setup your PTR account first.
Beta invite waves
Annual Pass
From March 29th, 2012 to April 19th, 2012, 1.2 million Battle.net accounts were given invites to the Beta based on Annual Pass signups.
Here are the six waves and the number of accounts added in each wave:
Sixth and mostly final wave of 400,000 on April 19th, 2012.[18]
Post Annual Pass
Around May 24th, 2012, WoW Insider reported that those who expressed interest (US, EU) in a beta on their Battle.net account will start getting invites.[19]
Cataclysm
This section concerns content exclusive to Cataclysm.
Starting late September of 2006, Blizzard started signing up Closed Beta Test testers for the first expansion, World of Warcraft: The Burning Crusade, from different playing areas. The plan was to introduce additional players to the beta test in subsequent waves, thus people that didn't make it in the starting lineup still had a chance at a Burning Crusade beta spot prior
to launch.[23]
The Closed Beta started in early October 2006. They were split into two servers:
Starting before March of 2004, Blizzard started signing up Closed Beta Test testers from an unknown pool of people using an undisclosed method of selection. The Closed Beta Trial ran for about 7 months ending in more widely available stress test and then an open beta before final release around the end of November 2004.
The "Closed Beta" was the first phase of Blizzard's stress test. There were three servers and virtually no lag existed. This closed beta is also known as the "First Stress Test". The servers were split up into the following:
^Nethaera 2012-03-22. #11 - How do you use addons?. Official Mists of Pandaria Beta > Beta Feedback forum (US). Addons are currently disabled in the beta. It's important that we do this so that we can tell the difference between a client error and an addon error. We'll notify everyone when we're at the point that we enable them again.
^Vaeflare 2012-06-27. UI Addons Enabled in the Next Beta Build. Official Mists of Pandaria Beta > Beta Feedback forum (US). Starting with the next Mists of Pandaria beta build, we plan to enable the use of UI addons.
