[galaxy-dev] Common workflow test tools

Hello galaxy community, I have a question regarding testing tools. I just setup a galaxy server to submit jobs to a cluster. Everything seems to be in order so far. Are there established workflows with test data that allow you to test a typical analysis (ex. RNA-Seq - from raw reads to counts, ChIP-Seq-from raw reads to enriched regions, SNP analysis-from raw reads to a VCF file etc). I want to be able run my tools on small test sets to make sure everything is fine and dandy, before I open it up to some beta testers. As an aside does galaxy have any dataset size limitations? Does it work equally well with an 8GB fastq/bam file compared to a 50-100GB fastq/bam? Thanks Ravi
