Ta-dah! Ta-dah!

Coding

Ok, time to start moving forward on the whole “Let’s wrap this thing in tests so we can safely replace all of the tech” thing. QA terminology varies between industries, between groups in the same industry, between people in the same group even; but I like to call this kind of stuff “arm’s length” testing. Tests run, or can run, on a separate machine from the code being tested, and are run on a “release” build. It’s pretty natural for client-server systems, where we’ll just pretend to be a normal client (for the most part).

Let’s start with a Cucumber feature file:

Feature: Login

Scenario: Logging in a new user
Given a new random user
And a telnet connection
When I create an account and character
Then I can play the game

And some definitions for those steps:

end

Then(/^I can play the game$/) do
  @connection.cmd({"String" => "1", "Match" => / ->/}) { |c| puts "12 #{c.gsub(/\e/, "[ESC]")}" unless c.nil? }
end

and we’re off to the races, once we define random_char_name.

To make sure I’m getting valid names, I started with code from the server’s CharGen.cs; specifically, CharacterNameDenied. But then why am I calling it with max_length of 10, and why no period in the acceptable array? Because I immediately ran into issues with the account name being rejected. A little digging found there were different rules there.

public static bool AccountNameDenied(string name)
{
    // check if account exists
    if (Account.AccountExists(name))
        return true;

    // check account name length
    if (name.Length < Account.ACCOUNT_MIN_LENGTH || name.Length > Account.ACCOUNT_MAX_LENGTH)
        return true;

    bool deny = false;

    string[] silly = new string[]{"pvp","lol","haha","hehe","btw","atm","jeje","rofl","roflmao","lmao","lmfao","lmho","dragonsspine",
                                    "dragonspine","nobody","somebody","anybody","account"};

    public const int ACCOUNT_MAX_LENGTH = 12;
    public const int PASSWORD_MIN_LENGTH = 4;
    public const int PASSWORD_MAX_LENGTH = 12;

So I’ll have to treat the various parts of the user a little differently. But for now, does this work?

A note about Cucumber

It looks like the online docs are being rewritten as we speak. I found saving a copy of the output of cucumber --help to be, well, helpful.

Playing

The Talos Principle

Second playthrough, about to try exploring the dialog trees now that I’ve done all of the main puzzles again.

Tearaway: Unfolded

Having played the original on the Vita, played through mostly to see the differences and to experience that world on the big screen. Even if you haven’t/won’t play it, go here for a glimpse of how it was built.

More to come
