 ## API Blueprint testability
 Dredd can test only API resources specified by *well defined transaction*. Any Non specific resources in the Blueprint e. g. with URI template or query parameters without default or example values are considered as *ambiguous transaction* thus they are resulting in a *warning* during the test run and are skipped.
 
+
