/**
* @class CppUnitTestRunner
* @ingroup cppunit
*
* @brief Application for running cppunit tests.
*
* This is an application to use when running cppunit tests, currently used
* in document,vdslib,storageapi and storage.
*
* It is built like a library, as one need to create one per project, but the
* cppunit test application file in each project can now only contain a little
* main method, creating an instance of this class and calling run.
*
* See storage/src/cpp/tests/testrunner.h for an example of simple app using
* this.
*
* When using this test binary you have the following options.
*
* If the TEST_SUBSET environment variable is set, only tests matching the
* pattern given in the environment is run. For instance, by doing
* TEST_SUBSET=foo ./testrunner, only tests that match the regular expression
* .*foo.* will be run. Optionally you can postfix your expression with a
* dollar, to only run tests that end with the given string. You can match
* against any part of the function shown in verbose mode. For instance
* TEST_SUBSET=foo::bar$ will run tests whose test class ends in foo, and
* having test name bar.
*
* You can specify --verbose mode. In verbose mode, each test name is printed
* to stdout when started, and after completion, the runtime of the test is
* shown. This is very useful to identify slow unit tests which should be
* improved, and also to see in what test the system might be hung up in. In
* addition, in verbose mode, a vespa log entry is given at the start and end
* of each test, such that one can identify which parts of the vespa log belongs
* to each test, in case you are redirecting the log to a file.
*
* You can also use the --includestress option to also include tests that match
* the regular expression '.*[sS]tress.*'. These are excluded by default, such
* that regular test runs can be quick.
