Jiri Daněk created DISPATCH-1783:
------------------------------------
Summary: Add ability to use test doubles (mocks, fakes, ...) in C
tests
Key: DISPATCH-1783
URL: https://issues.apache.org/jira/browse/DISPATCH-1783
Project: Qpid Dispatch
Issue Type: Improvement
Components: Tests
Reporter: Jiri Daněk
During the work on https://github.com/apache/qpid-dispatch/pull/684, there was
at one point a version which allowed to what happens if a {{vsnprintf}} called
from {{safe_snprinf}} returns {{-1}}.
This was done by replacing the {{vsnprintf}} with a mock (technically it's
probably a stub, or maybe fake, but let's ignore the proper terminology).
There are various possibilities how to approach mocking in C. They are less
nice than in more dynamic languages such as Java, or even C++ (where it's
possible to subclass things). Nevertheless, it can be useful technique, and it
should be explored.
