#' Run the R unit (and optional the JUnit) test suite for gMCP
#' Runs the R unit (and optional the JUnit) test suite for gMCP and prints the
#' results.
#' The environment variable GMCP_UNIT_TESTS may be used to specify which
#' unit tests should run: "extended", "interactive", "java" or a combination
#' of these separated by comma (without blanks). A short cut for all three is
#' "all".
#' @param extended If \code{TRUE} (or if the environment variable
#' GMCP_UNIT_TESTS equals "extended" or "all") an extended version of the R
#' unit test suite for gMCP will be used.  The run will take significantly
#' longer time.
#' @param java If \code{TRUE} (or if the environment variable
#' GMCP_UNIT_TESTS equals "java" or "all") the GUI and its logic is tested with JUnit tests.
#' You need JUnit 4 classes in the classpath or specify the path to a JUnit 4
#' jar file via the parameter junitLibrary.
#' @param interactive If \code{TRUE} (or if the environment variable
#' GMCP_UNIT_TESTS equals "interactive" or "all") the interactive part of the RUnit tests is
#' run.  The user have to look at results and answer questions.
#' @param junitLibrary A character String specifying the path to a JUnit 4 jar
#' file to run the JUnit tests.  You can download it from
#' \url{http://www.junit.org/}.  Alternatively you can use the environment
#' variable GMCP_JUNIT_LIBRARY to specify the path.
#' @param outputPath During the RUnit tests files maybe produced at this
#' location.  If missing the current working directory is used if nothing else
#' is specified in the environment variable GMCP_UNIT_TEST_OPATH.
#' Also the log of the results of the test suite is saved in this place.
#' @return None of interest so far - the function prints the results to the
#' standard output.  (Perhaps in future versions a value will be returned that
#' can be processed by the GUI.)
