neo4j - match a node that has direct links to all nodes in a set -


when there 2 nodes in set , it's relatively easy

match (a:article {id : "pmid:16009338"}),(c:article {id: "pmid:21743479"})  a, c  match (a)-[r]-(d)-[r1]-(c) return d

but similar attempt 3 nodes didn't work

match (a:article {id : "pmid:16009338"}),(c:article {id: "pmid:21743479"}), (p:article {id: "pmid:21741956"})   a, c, p match (a)-[r]-(d)-[r1]-(c)-[r2]-(d)-[r3]-(p)  return d

it looks different relation between c , d. r1 , r2. if change r2 r1 says : cannot use same relationship variable 'r1' multiple patterns.

even if make work impossible set of 4+ nodes.

==== attempt 3 nodes different types executes fast enough

match (a:article {id : "aid:16009338"}),(v:video {id: "vid:21743479"}), (s:song {id: "sid:21741956"})   a, v, s  match (a)-[]-(d)  d, v, s  match (v)-[]-(d)  d, s  match (s)-[]-(d)  return d

you common node against list of articles , make sure number matched afterwards same number matching against.

with ['pmid:16009338','pmid:21743479','pmid:21741956'] articles match (d)--(a:article) a.id in articles articles, d, collect(a) matched size(articles) = size(matched) return d

vue.js - Create hooks for automated testing -

Image
qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
