Re: GSoc 2015 | COUCHDB-1743 Make the view server & protocol faster
Dear All,
In past two weeks I have been reading the code(Erlang part). But I got a
problem when running the test cases
. The error what I get is *** context setup failed ***. What could be the
problem?

Sorry for the incompleteness of the problem.
*test:*
couch_mrview_all_docs_test.erl
*full error log(eunit): *
/usr/lib/erlang/bin/erl -pa /tmp/eunit_teamcity2.tmp -pa
/mnt/36024D48024D0E75/Users/Buddhika/Documents/Programming/2015/Apache/CouchDB/CouchProjects/couchdb-couch-mrview/out

-eval "eunit:test([couch_mrview_all_docs_tests], [{report,
{eunit_teamcity,[]}}, {no_tty, true}])." -s init stop -noshell
Testing started at 8:40 PM ...
Test suite was cancelled. Reason: {abort,
{setup_failed,
{error,undef,
[{test_util,start_couch,[],[]}]}}}Empty test suite.
*error log(by running "couch_mrview_all_docs_tests:test().")*
_all_docs view tests
*** context setup failed ***
**in function test_util:start_couch/0
called as start_couch()
**error:undef
*Here is the setup function of the test*
setup() ->
{ok, Db} = couch_mrview_test_util:init_db(?tempdb(), map),
Db.
I ran a test for tempdb. It perfectly returns a name for the database.

What the tests do you run?
For which case this error occurs?
Could you share full test run output?
