Problem: We're using a common pattern in our bats tests:
Run xrefcheck, redirect output to a temp file
Check the temp file matches some .gold file using `diff`
Delete temp file
We could encapsulate this pattern and make it easier to reuse.
Solution: In the `setup` function, create a temp directory. In the
`teardown` function, delete the temp directory. Create a `to_temp`
function that runs xrefcheck with desired options, pipes its output
through the `prepare` helper function and saves it in a file inside
the temp directory. Create a `assert_diff` function that reads the temp
file, and uses `diff` to compare it against some expected output.
Problem:
Almost all the time we can't validate localhost links, so we just skip them.
But to run ftp links tests (#47) we need to refer to localhost.
Solution:
Add config option whether to ignore localhost links and provide bats
tests for this new feature.
