Here is code that helps clients of modular with testing.

When linked against the //peridot/lib/testing library target, a test application can use the functions in lib/testing/testing.h to interact with the TestRunner service in its environment. This is the standard way to test multi-process modular applications; these functions allow a test to declare failure, and signal tear down of tests to the TestRunner service.

See //peridot/tests for more details on running tests.
