CI/CD Remote tests failing occasionally

[yaroslavyaroslav]

Sometimes remote tests failing on CI/CD. It runs well on rerun.

It's good to investigate the reason of this behaviour and to make remote tests more reliable.

When #685 will be merged into develop branch we could update some or all remote tests to use mocks.
It will eliminate the need for network to be even defined in the first place. It should reduce the chances of remote tests' failure.
I'll assign this issue to myself and will start updating remote tests when #685 is merged.

Note: mocking was introduced in #701 and it was merged into #685.
