ok 4 - ->setParameters() sets the parameters
ok 5 - ->setParameters() overrides the previous defined parameters
ok 6 - ->setParameters() converts the key to lowercase
# ->setParameter() ->getParameter() 
ok 7 - ->setParameter() sets the value of a new parameter
ok 8 - ->getParameter() gets the value of a parameter
ok 9 - ->setParameter() overrides previously set parameter
ok 10 - ->setParameter() converts the key to lowercase
ok 11 - ->getParameter() converts the key to lowercase
ok 12 - ->getParameter() thrown an InvalidArgumentException if the key does not exist
# ->hasParameter()
ok 13 - ->hasParameter() returns true if a parameter is defined
ok 14 - ->hasParameter() converts the key to lowercase
ok 15 - ->hasParameter() returns false if a parameter is not defined
# ->addParameters()
ok 16 - ->addParameters() adds parameters to the existing ones
ok 17 - ->addParameters() converts keys to lowercase
# ->setService() ->hasService() ->getService()
ok 18 - ->setService() registers a service under a key name
ok 19 - ->hasService() returns true if the service is defined
ok 20 - ->hasService() returns false if the service is not defined
# ->getServiceIds()
ok 21 - ->getServiceIds() returns all defined service ids
ok 22 - ->getService() looks for a getXXXService() method
ok 23 - ->hasService() returns true if the service has been defined as a getXXXService() method
ok 24 - ->getService() prefers to return a service defined with setService() than one defined with a getXXXService() method
ok 25 - ->getService() thrown an InvalidArgumentException if the service does not exist
