Noticed PHPUnit not set up like other repos, this PR sets up running PHPUnit like other repos. Although there are no steps.

How to test the changes in this Pull Request:

1. Run vendor/bin/phpunit on trunk.
2. Notice missing phpunit setup though xml dist is present.
3. Checkout this branch and run vendor/bin/phpunit.
4. Check test sample running and passing

For a complete setup, at least one real test should be added, and a test step added in CircleCI config. As it is, this PR does not add any value.

Hi @adekbadek makes sense! I've added simple tests for the widget. But it looks like this repo isn't currently setup to run CircleCI pipeline on forked PR, so the jobs aren’t running on PRs. could you assist here? TIA 🙇

@Takshil-Kunadia – I've updated the setting, try pushing an empty commit to trigger the build.
