I had a good google for this problem, and couldn’t find a solution, so I though I’d put my own here.
I’m running Jasmine tests through Karma. One of the components I’m testing logs error messages to the console, which is the desired behaviour in production but makes testing hard because methods fail silently.
This code snippet causes any calls to console.error(message) to throw an exception, ensuring that any tests that trigger errors will fail.

Daphne the Wondercat: monarch, fluffball, evil genius.
Daphne often takes to social media to rant about the inadequate service provided by her staff (tech journalist Kate Bevan). This activity is cathartic, and highly recommended for any household pet. Unfortunately, Daphne’s catflap was until recently mute, and couldn’t tell the world about its thoughts and feelings.
This was a pity, because Daphne’s catflap actually has a lot to tell the world. You see, the catflap *loves* daphne. Each time daphne passes through, its universe lights up with joy. Every time Daphne’s whisker brushes against it, a tremor of excitement passes through its little plastic body.
In this project, we gave the catflap a voice.

I’m Bernie. I’m a software developer and amateur photographer, and this is where I put my assorted articles, tutorials, opinion pieces, software release announcements and miscellany. I also have a portfolio website at berniesumption.com and a travel blog at bernieandju.de.
If you’d like to contact me for any reason, please do so: [email protected] or leave a comment on an article.
This article is the second in a series in which I implement the same app in several different graphical programming environments. Coming up this round: ActionScript.

In which I harness the power of public expectation to motivate myself to write more software posts, by loudly committing to write a series of three.
A graphics programming environment is a language or library suitable for drawing pretty patterns. In this series I’m interested in raster drawing environments, in which you can directly manipulate pixels rather than using higher level constructs like HTML or SVG. I intend to implement the same app in several different environments and compare the results.

I have a project to show y’all. I’ve been working on it in my spare time for the last half year, and while its not yet complete enough to be considered a product, the underlying technology is solid.
OGRE is a platform neutral technology for taking a data set on a server and creating real-time replicated slaves on clients. It’s fast. Very fast. It’s also highly extensible so it’s likely that OGRE can be adapted to fit your project, not vice versa.

When I started writing a travel blog almost half a year ago, I had a specific vision of how it would look. I wanted a big world map, onto which I would drop little pins. Each pin would be a single blog post, and clicking that pin would allow you to read the post in one of those little Google Maps speech bubble thingies.

My second big photography project, Vistagraphs, is an experiment in making photos that reflect the way that humans perceive the world. This is an explanation of what I mean by that.
