Provide Possibility To Reset Config Values

[sprankhub]

It is a good idea to properly isolate tests. However, this is currently not possible when working with configuration values.

Preconditions

1. Magento 2.3.3
2. MFTF 2.4.3

Steps to reproduce

1. Have a M2 installation of a client.
2. Write a test with config changes.
3. Run the test.

Expected result

1. After the test has run, the configuration should be exactly like before.

Actual result

1. It is currently not possible to reset config values to the values that were configured before the test was run. There should be a possibility to do so.

Hello @sprankhub, Thank you for your reporting!

As one of our best practice advice, if a test has altered Magento store configurations, the test should restore the configurations back to default at the end. There are a few ways to accomplish this, in general we recommend using magentoCLI action.

Currently we don't support restore the entire core_config_data table due to performance consideration.

Please let us know if this works for you.

Thanks for the feedback!

I would love to restore the configuration, but it is currently not possible. I can use magentoCLI to set a specific value. However, I cannot know what value was set before my test was run.

@sprankhub Before you change any configuration, login to Admin, change the configuration field of your interest to a new value and change it back, save the configuration, flush cache, run bin/magento config:show, you will get the default value for that field. Can you give this a try?

@jilu1 sorry for the late reply! I do not care about the default value of the field. I care about the value, which was set before I ran my test. I want to make sure that after my test, the value is set again to the value, which was set before my test ran. This is currently not possible...
