# set_temp_cache¶

class astropy.config.set_temp_cache(path=None, delete=False)[source]

Bases: astropy.config.paths._SetTempPath

Context manager to set a temporary path for the Astropy download cache, primarily for use with testing (though there may be other applications for setting a different cache directory, for example to switch to a cache dedicated to large files).

If the path set by this context manager does not already exist it will be created, if possible.

This may also be used as a decorator on a function to set the cache path just within that function.

Parameters
pathstr

The directory (which must exist) in which to find the Astropy cache files, or create them if they do not already exist. If None, this restores the cache path to the user’s default cache path as returned by get_cache_dir as though this context manager were not in effect (this is useful for testing). In this case the delete argument is always ignored.

deletebool, optional

If True, cleans up the temporary directory after exiting the temp context (default: False).
