# Cache Key Test Instructions
#
# Adding Tests
# ~~~~~~~~~~~~
# Cache key tests are bst element files created created in such a way
# to exercise a feature which would cause the cache key for an element
# or source to be calculated differently.
#
# Adding tests is a matter to adding files to the project found in the
# 'project' subdirectory of this test case. Any files should be depended
# on by the main `target.bst` in the toplevel of the project.
#
# One test is comprised of one `<element-name>.bst` file and one
# '<element-name>.expected' file in the same directory, containing the
# expected cache key.
#
# Running the cache key test once will reveal what the new element's
# cache key should be and will also cause the depending elements to
# change cache keys.
#
#
# Updating tests
# ~~~~~~~~~~~~~~
# When a test fails it will come with a summary of which cache keys
# in the test project have mismatched.
#
# Also, in the case that the tests have changed or the artifact
# versions have changed in some way and the test needs to be
# updated; the expected cache keys for the given run are dumped to
# '<element-name>.actual' files beside the corresponding
# '<element-name>.expected' files they mismatched with, all inside
# a temporary test directory.
#
# One can now easily copy over the .actual files from a failed
# run over to the corresponding .expected source files and commit
# the result.
