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 free for anyone to take. And then, either someone can grab one of those topics and pitch a talk on it, or it can be, like, inspiration where they see that it jogs their mind, and they have an idea that then they go off and write a proposal.

And so, that allows, I think, a lot of colleagues as well, who are maybe not interested in speaking but might have a lot of great ideas, to participate and sort of really get a lot of that energy going. And then, from there, people who are excited to speak about something can go on to maybe draft a proposal. And then, I've got a couple of other events where we support people in drafting a proposal and reviewing and submitting, things like that.

STEPHANIE: Yes, I really love how you're just involving people with, you know, just different skills and interests to be able to support each other, even if, you know, there's someone on our team who's, like, not interested in speaking at all, but they're, like, an ideas person, right? And they would love to see their idea come to life in a talk from someone else. Like, I think that's really cool, and I certainly appreciate it as a not ideas person [laughs].

JOËL: Also, I want to shout out that Ruby Central is doing CFP coaching sessions on June 24th, June 25th, and June 26th, and those are open to anyone. You can sign up. We'll put a link to the signup form in the show notes. If you've never submitted something before and you'd like some tips on what makes for a good CFP, how can you up your chances of getting accepted, or maybe you've submitted before, you just want to get better at it; I recommend joining one of those slots. So, Stephanie, what's new in your world?

STEPHANIE: So, I just successfully delivered a big project on my client work last week. So, I'm kind of riding that wave and getting into the next bit of work that I have been assigned for this team, and I'm really excited to do this. But I also, I don't know, I've been just, like, thinking about it quite a bit. Basically, I'm getting to spend two dedicated weeks to just refactoring [laughs] some really, I guess, complicated code that has led to some bugs recently and just needing some love, especially because there's some whiffs of potentially, like, really investing in this area of the product, and people wanting to make sure that the foundation does feel very stable to build on top of for extending and changing that code.

And I think I, like, surprised myself by how excited I was to do this because it's not even code I wrote. You know, sometimes when you are the one who wrote code, you're like, oh, like, I would love time to just go back and clean up all these things that I kind of missed the first time around or just couldn't attend to for whatever reason. But yeah, I think I was just a little bit in the peripheries of that code, and I was like, oh, like, just seeing some weird stuff. And now to kind of have the time to be like, oh, this is all I'm going to be doing for two weeks, to, like, really dive into it and get my hands dirty [laughs], I'm very excited.

JOËL: I think that refactoring is a thing that can be really fun. And also, when you have a larger chunk of time, like two days, it's easy to sort of get lost in sort of grand visions or projects. How do you kind of balance the, I want to do a lot of refactoring; I want to take on some bigger things while maybe trying to keep some focus or have some prioritization?

STEPHANIE: Yeah, that's a great question. I was actually the one who said, like, "I want two weeks on this." And it also helped that, like, there was already some thoughts about, like, where they wanted to go with this area of the codebase and maybe what future features they were thinking about. And there are also a few bugs that I am fixing kind of related to this domain. So, I think that is actually what I started with.

And that was really helpful in just kind of orienting myself in, like, the higher impact areas and the places that the pain is felt and exploring there first to, like, get a sense of what is going on here. Because I think that information gathering is really important to be able to kind of start changing the code towards what it wants to be and what other devs want it to be.

I actually also started a thread in Slack for my team. I was, like, asking for input on what's the most confusing or, like, hard to reason about files or areas in this particular domain or feature set and got a lot of really good engagement. I was pleasantly surprised [laughs], you know, because sometimes you, like, ask for feedback and just crickets. But I think, for me, it
