Description
Originally reported by: Bruno Oliveira (BitBucket: nicoddemus, GitHub: nicoddemus)
As described in #437 and #301, a test run stops when slaves collect a different number of tests.
This is the code that raises the error:
# dsession.py:147
def init_distribute(self):
assert self.collection_is_completed
# XXX allow nodes to have different collections
node_collection_items = list(self.node2collection.items())
first_node, col = node_collection_items[0]
for node, collection in node_collection_items[1:]:
report_collection_diff(
col,
collection,
first_node.gateway.id,
node.gateway.id,
)If instead of raising an AssertionError in report_collection_diff we just return None if the collections differ, we obtain a better error message.

Which makes it easy to track down the source of the problem (btw, the above issue has a proposed fix in pull request #192).
