Test the SDK
------------

[](#test-the-sdk)

Unit tests in this SDK can be run using PHPUnit.

1. First install the dependencies using composer including the `require-dev` dependencies.
2. Run `vendor\bin\phpunit --verbose` from commandline to execute tests. If you have installed PHPUnit globally, run tests using `phpunit --verbose` instead.

You can change the PHPUnit test configuration in the `phpunit.xml` file.
