Php Unit test case setup

[DevikVekariya]

• Create a setup for Php Unit Tests along with the documentation.

Acceptance Criteria:

• Each class and its method should pass though the Php Unit test case
• If any of the methods are ignored then, it should have proper docs with a reason to ignore it.
• It should have detailed documentation for the local setup of Unit tests and how to run it locally.

Can take a reference from here - rtCamp/login-with-google#19

@DevikVekariya
I need 24hrs to complete the task
Which includes learning and implementation
There is 3 different classes with 17 unique functions
The test will cover all the classes and the functions

Time estimation may vary because I will be starting learning as well as implementation completely from scratch

@dishitpala I wanted to split this issue between multiple folks.

• Create a new branch dev-unit-test from master.
• Create a new branch from the dev-unit-test to write the test case
• Setup the unit tests setup from reference Fixes #16 Unit test cases for plugin login-with-google#19
• Raise the PR from your test-case branch to dev-unit-test
• Make sure that we'll have one PR from dev-unit-test to master for all together

---

• Setup the unit tests from Fixes #16 Unit test cases for plugin login-with-google#19 => @dishitpala @thrijith
  Please add and merge ☝️above setup in this repo , so multiple folks can work on same parallely
• classes/admin.php => @dishitpala @thrijith
• classes/amp-admanager.php => @yahilmadakiya @vaishaliagola27
• classes/shortcode.php => @thrijith

The setup has been merged into https://github.com/rtCamp/amp-admanager/tree/dev-unit-test, tests for each classes can now be created from that branch as base.

Added case for classes/admin.php in https://github.com/rtCamp/amp-admanager/blob/add/admin-class-tests/tests/classes/test-class-admin.php, working on classes/shortcode.php currently.
