Any mistakes are my own. Basecamp is a modern software company that (by many estimates) generates millions of dollars in profit each month.

Promise not to promise

Since the beginning of Basecamp, we've been loath to make promises about future product improvements. We've always wanted customers to judge the product they could buy and use today, not some imaginary version that might exist in the future.

The wrong time for real-time

Chat puts conversations on conveyor belts that are perpetually moving away from you. If you're not at your station when the conversation rolls by, you'll never get a chance to put in your two cents. This means if you want to have your say, you need to be paying attention all day (and often to multiple rooms/channels). ... Chat is great for hashing stuff our quickly when speed truly is important. ... It's also great for watercooler-like banter ... building a camaraderie among people during gaps in the workday.

So you like to write some complicated tests plugged into your rake tasks. Or may be you think you're doing a crime not doing so. I understand. Nothing is wrong with that. But it's more like buying a helicopter so you can travel two blocks in Manhattan.

I'll explain:

1 - Rake tasks are not meant to be a complicated piece of your website. Instead, rake tasks are meant to be "thin" and only to invoke other modules in your system. Those modules do the heavy work. Those modules are what really matters. So, test the meaningful code and not the code that invokes it. Well, if you are still feeling unconfident about the invoking processes ... then:

2 - Trust rails and trust the whole framework. Don't bother testing whether this rake task is going to print something minor. It will work. Otherwise, you have a bigger issue that missing tests in the framework. 

In summary: Focus your energy more on testing the functionality that this rake task is written to invoke, which is a class or a method some where else in your
