/**
* A spock test runner which automatically applies instrumentation and exposes a global trace
* writer.
*
* <p>To use, write a regular spock test, but extend this class instead of {@link
* spock.lang.Specification}. <br>
* This will cause the following to occur before test startup:
*
* <ul>
* <li>All {@link dd.trace.Instrumenter}s on the test classpath will be applied. Matching
* preloaded classes will be retransformed.
* <li>{@link AgentTestRunner#TEST_WRITER} will be registerd with the global tracer and available
* in an initialized state.
* </ul>
