Just wrote a partial and small test script for t/Amap.t in bioperl-run. When I run "perl -I. t/Amap.t" I get the following output:
1..10
ok 1 - use Bio::Tools::Run::Alignment::Amap;
ok 2 - use Bio::AlignIO;
ok 3 - use Bio::SeqIO;
ok 4 - use Bio::Root::IO;
ok 5 - All the required modules are present
ok 6 - new() returned something
ok 7 -   and its the right class
not ok 8 - executable() got the correct filename
#   Failed test 'executable() got the correct filename'
#   in t/Amap.t at line 90.
#          got: undef
#     expected: 'filename'
ok 9 # skip Got incorrect filename for executable
ok 10 # skip Got incorrect filename for executable
# Looks like you failed 1 test of 10.


So far this looks good (well, that it's failing passing expected tests). However, when i run "make test" the output is unexpected and I don't know
why. It seems to die and produce the results of the testing before the rest of the test suit is run:
t/Amap....................NOK 8
#   Failed test 'executable() got the correct filename'
#   in t/Amap.t at line 90.
#          got: undef
#     expected: 'filename'
# Looks like you failed 1 test of 10.
t/Amap....................dubious
        Test returned status 1 (wstat 256, 0x100)
DIED. FAILED test 8
        Failed 1/10 tests, 90.00% okay (less 2 skipped tests: 7 okay, 70.00%)
t/Analysis_soap...........ok 7/17make: *** wait: No child processes.  Stop.



Is there something I'm missing?? If it's something less obvious, let me know and i'll post whole test file.
