Modern large-scale software design often requires ever-growing team 
sizes. As team size scales up, so does the amount of churn (and number 
of bugs introduced) to a code base in a release. Unfortunately, the 
amount of manual developer or QA testing necessary to find those bugs 
scales quadratically (or worse) as N features are tested by hand in M 
configurations. The solution is to keep coders, not QA, responsible for 
maintaining the quality of their individual components, and to make it 
trivial and fast to run just the right tests that cover the code the 
coder changes. D comes pre-baked with lots of tools to make this easier, 
including a standard unit testing harness, but there'smuch more we can 
build on top of that to help write not only tests for code, but code 
that can be tested in an automated fashion.

We'll discuss techniques and tools for designing large-scale testable 
code in D, including unit testing, mocks, fakes, inversion of control, 
and dependency injection.

Ben Gertzfield is a mobile engineer at Facebook. He's designed and 
shipped testability and dependency injection frameworks for Objective-C 
and C++, and is a huge advocate for freeing engineers from the burdens 
of manual testing.
