Harness MATCH tests refactored Summary: 1. Test setup rewritten to take cca 8 seconds. Note that edges are created by using: `MATCH (a) WITH a MATCH (b) WITH b WHERE rand() < X CREATE (a)-[:ET]->(b)` Where `X` is a threshold calculated so the desired edge count is the expectation. This seems the only feasable way of generating a large number of edges since query execution does not depend on edge count, but on vertex count. 2. Using the new `assert` function to verify graph state. I recommend doing that in all the harness tests (I don't think we currently have something better). 3. All tests rewritten to take around 200ms per iteration. 4. Test are using SKIP to avoid sending data to the client, but ensure that appropriate operations get executed. This currently seems like the best way of removing unwanted side-effects. Harness will cost us our sanity. And it doesn't even provide good quality regression testing we really need :( Reviewers: buda, mislav.bradac, mferencevic Reviewed By: mferencevic Subscribers: pullbot Differential Revision: https://phabricator.memgraph.io/D752 2017-09-05 19:54:28 +08:00			`from setup import LABEL_COUNT, LABEL_PREFIX`
