430: Test Suite Pain & Anti-Patterns The Bike Shed

Stephanie and Joël discuss the recent announcement of the call for proposals for RubyConf in November. Joël is working on his proposals and encouraging his colleagues at thoughtbot to participate, while Stephanie is excited about the conference being held in her hometown of Chicago!


The conversation shifts to Stephanie's recent work, including completing a significant client project and her upcoming two-week refactoring assignment. She shares her enthusiasm for refactoring code to improve its structure and stability, even when it's not her own. Joël and Stephanie also discuss the everyday challenges of maintaining a test suite, such as slowness, flakiness, and excessive database requests. They discuss strategies to balance the test pyramid and adequately test critical paths.


Finally, Joël emphasizes the importance of separating side effects from business logic to enhance testability and reduce complexity, and Stephanie highlights the need to address testing pain points and ensure tests add real value to the codebase.

Transcript:


STEPHANIE: Hello and welcome to another episode of The Bike Shed, a weekly podcast from your friends at thoughtbot about developing great software. I'm Stephanie Minn.


JOËL: And I'm Joël Quenneville. And together, we're here to share a bit of what we've learned along the way.


STEPHANIE: So, Joël, what's new in your world?


JOËL: Something that's new in my world is that RubyConf just announced their call for proposals for RubyConf in November. They're open for...we're currently recording in June, and it's open through early July, and they're asking people everywhere to submit talk ideas. I have a few of my own that I'm working with. And then, I'm also trying to mobilize a lot of other colleagues at thoughtbot to get excited to submit.


STEPHANIE: Yes, I am personally very excited about this year's RubyConf in November because it's in Chicago, where I live, so I have very little of an excuse not to go [laughs]. I feel like so much of my conference experience is traveling to just kind of, like, other cities in the U.S. that I want to spend some time in and, you know, seeing all of my friends from...my long-distance friends. And it definitely does feel like just a bit of an immersive week, right? And so, I wonder how weird it will feel to be going to this conference and then going home at the end of the night. Yeah, that's just something that I'm a bit curious about. So, yeah, I mean, I am very excited. I hope everyone comes to Chicago. It's a great city.


JOËL: I think the pitch that I'm hearing is submit a proposal to the RubyConf CFP to get a chance to get a free ticket to go to RubyConf, where you get to meet Bike Shed co-host Stephanie Minn.


STEPHANIE: Yes. Ruby Central should hire me to market this conference [laughter] and that being the main value add of going [laughs], obviously. Jokes aside, I'm excited for you to be doing this initiative again because it was so successful for RailsConf kind of internally at thoughtbot. I think a lot of people submitted proposals for the first time with some of the programming you put on. Are you thinking about doing things any differently from last time, or any new thoughts about this conference cycle?


JOËL: I think I'm iterating on what we did last time but trying to keep more or less the same formula. Among other things, people don't always have ideas immediately of what they want to speak about. And so, I have a brainstorming session where we're just going to get together and brainstorm a bunch of topics that are fr
