Re: [pgadmin4][Patch]: Test cases for the backup module - Mailing list pgadmin-hackers

Hi Victoria,

Thanks for reviewing the patch.

The tests were failing due to the latest commit #2b4605a9d390cb44e5dfe9967c3adf2b28d04f1f  - Ensure backup/restore/maintenance work via SSH tunnels. Fixes #3355

I have fixed the issues and attached the updated patch.

Thanks,

Khushboo

Hi there,

We've been noticing some issues with the tests on both our CI and local Mac workstations.

1. When the following code blocks are invoked - we get plenty of app.context() issues. It must not be valid when running tests.

​

from pgadmin.utils.driver import get_driver
driver = get_driver(PG_DEFAULT_DRIVER)
manager = driver.connection_manager(self.sid)

host = manager.local_bind_host if manager.use_ssh_tunnel else s.host
port = manager.local_bind_port if manager.use_ssh_tunnel else s.port 

2. When we finally enable 

"default_binary_paths": {

in our test_config, we get more failing tests that look like:

======================================================================
FAIL: runTest (pgadmin.tools.restore.tests.test_restore_create_job_unit_test.RestoreCreateJobTest)

Hi,

Please find the attached updated patch with the fixes.

The test cases were only failing on MAC not on Linux.

Thanks,

Hi,

2. End to end regression test cases 

3. Feature test cases

Thanks. I've yet to be able to run the feature tests successfully. Here's what I've found so far:

1) DEFAULT_BINARY_PATHS should be default_binary_paths in the JSON config file.

Will do. 

2) I've hit screensize related issues:

Thanks.

I have ran the feature tests with multiple servers many times but didn't get a single failure.

I have asked Akshay to run on his machine, let see what he gets.

Hi Khushboo,

We reviewed the patch and it is very nice to see some more coverage in this area. Good job :D

We passed the tests through our CI the feature tests are not passing, but the linter fails:

For the feature tests, we realized we had to update the configuration, and we did that, but we get the following error attached. We spent some time trying to understand the problem but we were not successful.

Codewise:

- We just found some One Letter Variables in the code...

- Looks like there is a bug report in this area of the code and we do not have coverage for it: https://redmine.postgresql.org/issues/3232

  Looks like in some of the unit tests we only have happy path tests, maybe we should see if there are any sad paths that also need coverage.

The configuration change, maybe need to be updated. When we install multiple versions of postgres the binaries live in `/usr/lib/postgresql/{{db_version}}/bin`, which makes us think that this configuration should live near the server configuration, maybe? Also to maintain coherency on the naming maybe we should make it all lower case.

Just as an aside, you can add the gpdb configuration as well in you patch.

Thanks

Victoria & Joao
