    Determines if a path is 'valid' for this source.

    Determines if a path is 'valid' for this source. In strict mode all paths must be valid. In non-strict mode, all invalid paths will be filtered out.

    Subclasses can override this to validate paths.

    The default implementation is a quick sanity check to look for missing or empty directories. It is necessary but not sufficient -- there are cases where this will return true but there is in fact missing data.

    TODO: consider writing a more in-depth version of this method in TimePathedSource that looks for TODO: missing days / hours etc.

    The mock passed in to scalding.JobTest may be considered as a mock of the Tap or the Source. By default, as of 0.9.0, it is considered as a Mock of the Source. If you set this to true, the mock in TestMode will be considered to be a mock of the Tap (which must be transformed) and not the Source.
