Example 2 with ExpressionLanguage

use of org.mule.runtime.api.el.ExpressionLanguage in project mule by mulesoft.

the class TestServicesConfigurationBuilder method doConfigure.

@Override

            // Force initialization of internal DataWeave stuff
            // This way we avoid doing some heavy initialization on the test itself,
            // which may cause trouble when evaluation expressions in places with small timeouts
