l.t.l.LayerIsolationError(LayerError) : class documentation

Part of lp.testing.layers View In Hierarchy

Test isolation has been broken, probably by the test we just ran.

This generally indicates a test has screwed up by not resetting something correctly to the default state.

The test suite should abort if it cannot clean up the mess as further test failures may well be spurious.
