# Test 'fossil stash' against expected results from 'fossil changes' and
# 'fossil addremove -n', as well as by verifying the existence of files
# on the file system. Unlike the similar function found in
# revert.test, 'fossil undo' is not called after each test because
# many stash operations aren't undoable, and because further testing
# of the stash content is more likely to be useful.
#
# The extra list "-knownbugs" is a list of areas that should be
# marked as "knownBug" to the inner call to test. Known areas are:
#  -code       The exit status of fossil stash
#  -result     The result string didn't match
#  -changes    The changed file set didn't match
#  -addremove  The addremove result set didn't match
#  -exists     One or more listed files don't exist
#  -notexists  One or more listed files do exist
#
# Also, if the exit status of fossil stash does not match
# expectations, the rest of the areas are not tested.

# is replaced by the revert.
