-2 jobs have been created, one to run all the test and one that allows testing
-test suite by test suite.

-tests shall be automatically run.
+As mentioned in `[1]`, the *prepare-env.sh* and *run_test.sh* can be called within

+explained in the previous section. One job runs all the tests and the other one allows testing
+test suite by test suite specifying the test name. The user might use one or
+the other job to execute the desired test suites.

+One of the most challenging task in the Brahmaputra release consists
+in dealing with lots of scenarios and installers. Thus, when the tests are
+automatically started from CI, a basic algorithm has been created in order to
+detect whether a given test is runnable or not on the given scenario.
+Some Functest test suites cannot be systematically run (e.g. ODL suite can not
+be run on an ONOS scenario).
