That's exactly the problem.

I was expecting it to be produced as part of the output of scan_deps() and the subrountine generic_rv_test() is therefore testing that it was produced.
The only thing that I can think of that might explain this is that the data stucture $rv hasn't been completely filled out, as a result of scan_deps(), before it's used by generic_rv_test() except in the case when I dump $rv. However, that strikes me as being unlikely.

I assume you mean give you the full code so here it is:
The test script (4-pluggable_fake.t)"
NB if I uncomment either of the two groups of comments in the above I get the used_by => ["Foo.pm"], line I'm testing for and all is OK.
The complete generic_rv_test subrountine:
And finally, the subroutine scan_deps comes from the CPAN module Module::ScanDeps.
Thanks for the help, Adrian |
