[ABW]: various tests marked as passing, one wrong pattern fixed

See merge request !27

jsondiff changed to deepdiff

See merge request !24

# Conflicts:
#   hivemind/tavern/test_bridge_api_patterns.tavern.yaml

Updated patterns for bridge_api, database_api (fixes) and others due to changes in HiveMind

See merge request !26

accepted differences in post_id in new patterns
added comments on bridge_api failing tests now that there is less differences
corrected patterns for database_api (one test also changed to fit interface of fat node - completely stopped working for new HiveMind due to API difference)

bridge_api patterns corrected

See merge request !23

- jsondiff has a bug/feature: if you compare not empty json object with
  empty json object it will show no difference. Comparing empty with not
  empty will show difference
- jsondiff its not actively maintained (last commit 11 months ago)

[ABW]: patterns changed as old ones seemed to come from fully synced node - new ones are from 5mln blocks
some tests changed to give nonempty results
fixed rebranding and accepted slight differences in pending payouts (expected)
one pattern broken manually - needs to be investigated because it did not make the test to fail!
indentation in patterns changed to 2 spaces
added comments on why tests are failing

Various dates corrected in patterns

See merge request !21

Tests that only differed by last_payout now marked as passing
Creation time of accounts changed one block earlier to match what old FatNode was giving (unknown discrepancy between FatNode and old HiveMind)

[ABW]: updated comments for tests that started to work a bit better

See merge request !20

Added possibility to ignore given fields in json

See merge request !18

[ABW]: some tests marked as no longer failing

See merge request !19

slight differences in pending payout (expected) accepted in some patterns that had no other problems

- Response validator can now ignore specified fields in
  json response when comparing with patters
- Example in get_profile in bridge_api

Changes in patterns

See merge request !17

Patterns corrected for condenser/follow/tags_api groups (both old and tavern)

See merge request !16

- rebranding
- accepted different future cashout_time (prior to HF17 it was taken from root and we don't want to introduce hardfork differences to HiveMind)
- accepted different post_id
- accepted lack of double-escaped slashes in json_metadata (now is better)
- corrected indent for tavern's 2 spaces
- corrected cases of CLRF
Comparison script now removes .diff.json and .out.json files from previous run
Comparison script now generates .out.json with error message in case of error/no response (all failing tests have .out.json file)
Added comments to failing tests why they are failing
Added comments to tests with empty results why there is no other option

Set of tests for hivemind using tavern library

See merge request !15

- Added xfail mark to failing tests

- Defined marks in proper way in pytest.ini.
- Added condenser_api pattern test yaml definitions.
- Changed xfail marks to failing marks.
- Update readme file with comments on marking.

- Added pattern validator
- Added patterns for 5000000 blocks
- Added bridge_api pattern tests - failing tests are marked with XFAIL
- Added marks to all tests

- Response validator has been added: it validates if error or result
  fields are present in response. Occurence of error field will fail
  the given test.
- In order for validator to work a path to test directory must be added
  to PYTHONPATH i.e you can run py.test from inside of tavern dir using:
  PYTHONPATH=$PYTHONPATH:$(pwd) py.test -v

- Initial implementation of tests with tavern freamework
- All tests are green atm because only thing that is checked is
  response_conde
- More works on tests in next commits

add condenser api get_active_votes test
