ConfigManager is as synonymous to any other configuration facility provided for products. Currently, we provide configuration as part of some file say json\cfg and provide the command line option to use that. Now, there are places where the hard coding specific to setup\data is done inside of test data. I have given one simple example related to ldap search and replace. In order to replace these issues, we can use the ConfigManager facility added. We can now extend it to some more usecases if required. It has now some provision to read the config, abstract to users and obtain to test features as easy to use dictionary.
The new facility added handles all that mentioned in doc strings. It has a simple interface to retrieve the configuration provided and users can use it easily inside the test features as a dictionary. With this, all configuration pertaining to run will be at one single place and we provide a simple usage of this through dictionary. It doesn't have any setters for that matter. With this, all hard coding will be moved to configuration and users use the dynamic dictionary created based upon config and is more driven through config. We can remove current not a cleaner way of search and replace with this. Currently, testclient provides apiclient,dbconnection and added to it will provide configuration interface as well. Using this, test features will get configuration facility for his feature for use. Users mention all parameters related to their test in config file, and they have a dictionary of the parsed config inside of their tests to use this data. The user don't need to hard code this. Of a test as we are doing currently. On a given setup they can use a different config and it works to work with those ips set up infrastructure dynamically. If I have a ldap server ip different from other, the code still works, we just need to change the config. The features, where this hard coding is done will now be replaced with this usage of moving those hard coded strings to configuration file and replace those with config dictionary values, which will be filled in dynamically. What else you see is missing? Let me know and I can enhance it to add.

I've given some inline comments in the patch. The ConfigManager looks too simple perhaps because it's a WIP? At least the goals as you've written in your docstring seem to talk about more than what's provided in the module.

This seems restrictive because previously one could have their configs placed anywhere. what would be the advantage of placing all configs in tools/marvin/marvin/config? When packaged and deployed this path is going to change to /usr/local/lib/python/site-packages/marvin/config. Do we want that? > They can remove all hard coded values from code and separate > it out as config at this location. How would the ConfigParser know where to find a specific section and at what depth? Is there a structure? Or do you leave that up to the test author? I'd rather not do the latter as things go wild with too many different ways to do the same thing. > Either add this to the existing setup.cfg as separate > section > or add new configuration. > 3.

If we unify all data into the deployment json it's going to become a mess to manage, edit and control when running tests. > > 4.

I like it that it's part of the testClient, wil you be providing setter properties to it if it's part of the testClient via ConfigManager. Test case authors might be tempted to change configuration on the fly which might affect downstream tests in the same suite? > > 5.
