Hollis: For Developers, 'One Size Fits All' Doesn't Fit
Giving a keynote presentation at the VSLive! conference this week, noted speaker Billy Hollis decried the "fixation" on unit testing, among other topics.
In an industry changing as rapidly as the technology industry, there's no such thing as a universal solution. That was the primary message of Billy Hollis's keynote address at Visual Studio Live! earlier this week. Hollis, principal consultant with Next Version Systems, spoke on the current state of conventional wisdom in the application development world and how developers can and should take a more realistic, practical view.
"I've always had a bit of a contrarian view," said Hollis. In fact, his keynote session was entitled, "There's No Future in the Past: A Critique of Conventional Thinking on the Radical Changes in Our Industry."
"There are certain things people push as the only way to do things, and they just aren't universally applicable," he said. "My skepticism is shared by lot of people, but they don't hear that message in public."
And it's not just changes in technology that outpace organizational evolution, according to Hollis. Development practices and business processes also need to change. "There are certain processes developers like," he said. "Certainly development teams, depending on the size, that's a good approach. Others don't need that. It can be a straitjacket on how you think about software development."
Testing is another process upon which developers and businesses often place too much emphasis, said Hollis. "There's a fixation on unit testing. Everything should have a unit test," he said. "Unit testing has enormous value. I just don't believe you should be dogmatic about it. It gives up a lot of innovation in the client space." Certain aspects of visual code, he said, defy the processes of unit testing. "If you unit test everything, you're committing to not using those techniques, even though they're good for the users."
It all comes down to matching the solution with the challenge, Hollis said. "Our industry is changing too fast for there to be one true way of doing anything."
Visual Studio Live! was held May 5-8 in Chicago. The next event is on the Microsoft campus, from Aug. 18-22.
