Note that`default_conf()` is called by`init()` function; both of them overwrite

the configuration file, which means that they should be called before`append_conf()`.

Testgres supports the creation of PostgreSQL nodes on a remote host. This is useful when you want to run distributed tests involving multiple nodes spread across different machines.

To use this feature, you need to use the RemoteOperations class.

Here is an example of how you might set this up:

from testgresimport ConnectionParams, RemoteOperations, TestgresConfig, get_remote_node

conn_params= ConnectionParams(

host='your_host',# replace with your host

username='user_name',# replace with your username

)

os_ops= RemoteOperations(conn_params)

TestgresConfig.set_os_ops(os_ops=os_ops)

deftest_basic_query(self):

with get_remote_node(conn_params=conn_params)as node:

node.init().start()

res= node.execute('SELECT 1')

self.assertEqual(res, [(1,)])

./run_tests.sh

1. Start remote host or docker container

2. Make sure that you run ssh

3. You need to connect to the remote host at least once to add it to the known hosts file

4. Generate ssh keys

5. Set up params for tests

`test_remote` - Tests for RemoteOperations class.

`test_simple_remote` - Tests that create node and check it. The same as`test_simple`, but for remote node.
