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 is 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.

I'm assuming it will take 3-4 days. I'll try to finish as soon as possible. I've considered some extra buffer, because working for the first time.

@kiranpotphode 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 from https://github.com/rtCamp/wp-google-login/pull/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

• [x] Setup the unit tests from https://github.com/rtCamp/wp-google-login/pull/19 => @kiranpotphode Please add and merge ☝️above setup in this repo , so multiple folks can work on same parallely

@kiranpotphode Can you merge this branch #45 to your branch with PHPUnit configuration and close this PR. As master branch does not contain a unit test setup and we cannot merge it without checks passing.

@deepaklalwani97

Raise the PR from your test-case branch to dev-unit-test

Merge your PR to dev-unit-test, then all will pull dev-unit-test to their working branch.

[deepaklalwani97]

Merged to dev-unit-test

@juhi123 The dev-unit-test branch needs to be QA tested before we can merge it to develop. Please test the dev-unit-test branch and add your findings.
