Hi list,

I’ve been trying to write functional tests for a tool that produces BAM
files as output. The tests run fine when using planemo locally,
but not on the testtoolshed or on machines that do not have samtools installed.
Apparently galaxy automatically tries to convert BAM to SAM to compare
the output line by line, and so this fails. Surprisingly this is also true when
comparing by size.
This is the error:

Tool id: bowtieForSmallRNA
Tool version: bowtieForSmallRNA
Test: test_tool_000000 (functional.test_toolbox.TestForTool_testtoolshed.g2.bx.psu.edu/repos/drosofff/msp_sr_bowtie/bowtieForSmallRNA/1.1.0)
Stderr: 

Traceback:

Should samtools perhaps be added to the list of tools required for running galaxy?

Best,
