Profile based segregation
====================
We are using maven build profiles to segregate the huge list of individual projects we have in our repository.
The projects are broadly divided into 3 list: first, second and heavy.
Next, they are segregated further on the basis of tests that we want to execute.
Therefore, we have a total of 6 profiles:
| Profile | Includes | Type of test enabled |
| ----------------------- | --------------------------- | -------------------- |
| default-first | First set of projects | *UnitTest |
| integration-lite-first | First set of projects | *IntegrationTest |
| default-second | Second set of projects | *UnitTest |
| integration-lite-second | Second set of projects | *IntegrationTest |
| default-heavy | Heavy/long running projects | *UnitTest |
| integration-heavy | Heavy/long running projects | *IntegrationTest |
Building the project Building the project
==================== ====================
To do the full build, do: `mvn clean install`
Though it should not be needed often to build the entire repository at once because we are usually concerned with a specific module.
But if we want to, we can invoke the below command from the root of the repository if we want to build the entire repository with only Unit Tests enabled:
`mvn clean install -Pdefault-first,default-second,default-heavy`
or if we want to build the entire repository with Integration Tests enabled, we can do:
`mvn clean install -Pintegration-lite-first,integration-lite-second,integration-heavy`

Running Tests Running Tests
============= =============
The command `mvn clean install` will run the unit tests in a module. The command `mvn clean install` from within a module will run the unit tests in that module.
To run the integration tests, use the command `mvn clean install -Pintegration-lite-first` For Spring modules this will also run the `SpringContextTest` if present.
To run the integration tests, use the command:
`mvn clean install -Pintegration-lite-first` or
`mvn clean install -Pintegration-lite-second` or
`mvn clean install -Pintegration-heavy`
depending on the list where our module exists
