What!!
I use the same code in ci testing. CI give two different result.
What's happened?

[steven-supersolid]

For some reason another change in meetup.js is being considered - perhaps your branch is not up to date with master?

[trylovetom]

@steven-supersolid Really? I have been rebase to the latest master.

[flovilmart]

You should probably run the tests locally, before opening the PR, as it’s notifying all maintainers.

@flovilmart How can I switch the db of testing to postgres, please. I really need this feature.

[flovilmart]

PLease read the contributing guide https://github.com/parse-community/parse-server/blob/master/CONTRIBUTING.md

[trylovetom]

@flovilmart thx

[trylovetom]

@flovilmart I need help, I wrote the testing code of handleShutdown(). But I didn't know how to test it correctly. Can you give me some tips?

[flovilmart]

To test the code locally with postures, you need postgres 9.5.
then you'll need to setup a few things as PostGis extensions and the test DB:

$ psql -c 'create database parse_server_postgres_adapter_test_database;' -U postgres
$ psql -c 'CREATE EXTENSION postgis;' -U postgres -d parse_server_postgres_adapter_test_database
$ psql -c 'CREATE EXTENSION postgis_topology;' -U postgres -d parse_server_postgres_adapter_test_database

Then to run the tests:

$ PARSE_SERVER_TEST_DB=postgres npm test
