### Test pass locally but fail on test nodes, what can I do ?
At the end of the test, a snapshot of the slapos instances is created. Sometimes examining the log files can help understanding what went wrong.
Most of the time, problems are because on test nodes paths are very long. One advanced technique to reproduce the problem in your development environment is to set `SLAPOS_TEST_WORKING_DIR` environment variable to a path with the same length as the ones on test nodes.
One way to make instances uses a slightly shorter path is to define `__partition_reference__` class attribute, so that the instances uses this as prefix instead of the class name.
