Centralizing the custom properties defined for Environments. Want to read values from a config file.

[Madhusm]

We have projects created which has to be executed across N environments. Currently it is quite cumbersome to manually create environments and maintain it.
For example I have an environment defined XYZ and a custom property defined .Now if there is a change in the property value have to manually edit all the projects for the property to get updated.

How can I use one centralized file with all properties defined and based on the environment it can make the changes to that environment. What are the options I have to implement this?

Sample Config file 

Env1=Beatrice
Env1.NodeID=123456789
Env1.APIKey=Abnjjjkj89090909
Env2=Alex
Env2.NodeID=4665656565656
Env2.APIKey=Abjjkjkj87887878787
EnvN=XYZ
EnvN.NodeID=467878799956565656
EnvN.APIKey=MNKKjjkjkj87887878787

I have projects with environments defined as in the snapshot attached, now I want to set these properties from a generic config property file which has these properties defined with different values based on the environment. So when I execute the test I want that properties are extracted from the generic config file at the time of execution based on the environment chosen.

Like to hear from you if that is at least suites what you are looking if you didn't get chance to try yet.

@nmrao Hey I will try to implement this around next week. Will surely let you know about it.
