TST: Use tempfiles in all tests. by jtratner · Pull Request #5419 · pandas-dev/pandas (original) (raw)

@jreback the point isn't to maintain the file path, it's that all the files we create for testing need to go into the temp directory. I added that make_tempfile=False part to work around pytables tests (otherwise they get littered everywhere). For example, I get this error when I try to use it with tempfile:
