/**
 * Trait that causes StackDepth exceptions thrown by a running test (such as TestFailedExceptions) to have
 * the exception's stack trace severed at the stack depth. Because the stack depth indicates the exact line of code that caused
 * the exception to be thrown, the severed stack trace will show that offending line of code on top. This can make the line
 * of test code that discovered a problem to be more easily found in IDEs and tools that don't make use of
 * ScalaTest's StackDepth exceptions directly.
