jjrodrig opened a new issue #1156: Tests for db,doc and attachment operations with different quorum situations
URL: https://github.com/apache/couchdb/issues/1156
 
 
   ## Expected Behavior
   - Have a uniform response status code when the quorum is not met. 202 - Accepted
   - Have a uniform managemente of the W parameter specified at the DB creation time
   
   ## Current Behavior
   <!--- If describing a bug, tell us what happens instead of the expected behavior -->
   <!--- If suggesting a change/improvement, explain the difference from current behavior -->
   
   I've been doing some testing that checks if the db, docs and attachment operation are returning the proper http status code depending on the cluster quorum conditions. I hope this can help.
   
   I've tested in the following scenarios:
   
   **Test in a 3-node cluster with only 1 node up**
   - DB created with default write quorum (quorum is not met)
   - DB created with overridden write quorum, param W=1 (quorum is met)
   
   This table shows the result

   **Test in a 3-node cluster with 2 nodes up**
   - DB created with default write quorum (quorum is  met)
   - DB created with overridden write quorum, param W=3 (quorum is not met)
   
   This table shows the result
   ![image](https://user-images.githubusercontent.com/1001724/36021348-cf29ced4-0d85-11e8-8f0f-e40951efffa6.png)
   
   It shows an uneven behaviour between operations:
   
    - Delete DB is producing error when quorum is not met (Issue #1136)
    - Create and Delete DB are not managing overridden quorum
    - Document operations are ok except copy operation which is not managing overridden quorum
    - Attachment operations are not managing overridden quorum
    - Attachment deletion is not considering default quorum
   
   ## Possible Solution
   <!--- Not obligatory, but suggest a fix/reason for the bug, -->
   <!--- or ideas how to implement the addition or change -->
    - For Error 500 during DB deletion is fixed by #1139
   
   ## Steps to Reproduce (for bugs)
   I'll link with this issue a PR that contains the test cases I've added for the tasks test-cluster-with-quorum/test-cluster-without-quorum
   
   ## Context
   Finding consistency in the HTTP API responses
   
   ## Your Environment
   I've tested compiling the current master
