I used to think git submodules were categorically evil. This was naive, as most choices in software development are about tradeoffs. A part of the reason I had this simplistic view was because of an article called “Why your Company Shouldn’t use Git Submodules.” I took a second look at this article recently and I read the docs on git submodules. What follows are some more nuanced thoughts on how and when git submodules can be used effectively. »
A part of the TDD work flow is getting a failing test to pass as quickly as possible. This makes sense if we think about how TDD is supposed to help us take smaller steps when we’re writing programs. Beck goes over three ways of getting a test to pass quickly in the fist part of TDD By Example. The first method is to fake it. Just hard code whatever values you need to to get the tests to pass. »
Red, green, refactor. That’s the TDD flow. That much was obvious to me. However, refactoring is a pretty broad term. There are many reasons you may want to refactor code and as a result of this, I didn’t really understand what exactly was supposed to happen during the refactor step of the TDD loop until I finished the first part of Kent Beck’s TDD by Example. Actually, in the first description of TDD, Beck uses a more helpful description of the “refactor step. »
Kent Beck introduces TDD by Example with a little story meant to show the business value of automated testing: Early one Friday, the boss came to Ward Cunningham to introduce him to Peter, a prospective customer for WyCash, the bond portfolio management system the company was selling. Peter said…“I’m starting a new bond fund, and my strategy requires that I handle bonds in different currencies.” The boss turned to Ward, “Well, can we do it? »
According to Eric Reis, MVPs allow us to test our business’ most important “hypotheses.” This is supposed to help us “fail faster,” but I’m finding that there are real differences in how much effort we have to put into our MVPs before we can validate our business hypotheses. In other words, some MVPs are more capital intensive than others. This is a big deal because you often can’t get favorable investment terms until you’ve shown that you’ve got product-market fit. »
If you’re going to be successful, Richard, you need to learn to be an asshole. Erlich Bachman, Silicon Valley For those of you who don’t know, I was recently accepted into Starter Studio, an Orlando-based incubator to work on University Android, a codeacademy-like program for learning Android development. Every Monday night, Starter Studio brings in successful founders to talk about things they’ve learned along the way to success. »
When building our Android apps, we can often wind up with a decent amount of code in our
RecyclerView.Adapters that we want to test. In this article, I briefly suggest two ways of structuring our
RecyclerView-related classes so that we can accomplish this.
Loaders are awesome…they’re essentially the best practice implementation of asynchronous data loading in your Activities.

I’ve been working on a unit test recorder for Android. After struggling to find a way to implement the unit test recorder,1 I decided to take a look at how Google implements the espresso test recorder. This post presents what I found when I dug into the source code of the espresso test recorder. Collecting User Interaction Info Before I took a look at the source for the espresso recorder, I half expected to find some fancy bytecode manipulation of the sort we see for the proguard or jacoco transformers. »
Last week, I introduced Vice, a proof of concept regression test generation library. Vice generates regression tests simply by exercising the code we want to test. This is neat, but there’s already something else out there that does something like this, and ultimately, Vice as it stands doesn’t answer a fundamental question I have about regression tests: if we can record functional UI tests using the espresso test recorder or apple’s test recorder, why don’t we have a unit test recorder? »
