> 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
> Affects Versions: 1.14.0
> Reporter: Jiri Daněk
> Priority: Major
>
> During the work on https://github.com/apache/qpid-dispatch/pull/684, there
> was at one point a version of the PR, which tested what happens if
> {{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.
