Skip OpenCL tests in continous integration (CI) environment
CI environment (a virtual machine) does not support OpenCL calls. I.e., an exception is thrown during tests.
Therefore, disable OpenCL tests in CI environment. Instead of just call mvn test
use something like mvn "-Dtest=!SkippedClass"
(see http://maven.apache.org/surefire/maven-surefire-plugin/examples/single-test.html#Multiple_Formats_in_One).
