Caveat: this will make the tests reproducible only as long as you keep using the same platform (or perhaps even perl version, or compilation option). For example, the following program 
perl -le "srand(0); print rand"

[download]
gives me the following results: 
0.00115966796875   v5.8.4 built for MSWin32-x86-multi-thread
0.17082803610629   v5.8.0 built for i686-linux
