Setup

  $ export AUGUR="${AUGUR:-$TESTDIR/../../../../bin/augur}"
  $ export SCRIPTS="$TESTDIR/../../../../scripts"
  $ export ANC_DATA="$TESTDIR/../../ancestral/data/simple-genome"
  $ export DATA="$TESTDIR/../data/simple-genome"

Similar tests to those in `general.t` but here testing the --genes argument.
Note that the output is a little misleading, as it's counting the 'source' GFF ID
as a feature ('nuc' in this case)

  $ ${AUGUR} translate \

  >  --reference-sequence "$DATA/reference.gff" \
  >  --genes gene2 gene3 \

  Couldn't find gene gene3 in GFF or GenBank file
  Read in 2 features from reference sequence file
  Validating schema of .+ (re)
  amino acid mutations written to .+ (re)

  {}
Using a text file rather than command line arguments

  $ echo -e "#comment\ngene2\ngene3"> "genes.txt"

  Read in 2 specified genes to translate.
