Sergey Zhuk has posted the latest part of his "Building a ReactPHP Memcache client" series to his site today. In this latest article, part four of the series, he focuses on unit testing the client as he's developed it so far.
This is the last article from the series about building from scratch a streaming Memcached PHP client for ReactPHP ecosystem. The library is already released and published, you can find it on GitHub. In the previous article, we have completely finished with the source code for async Memcached ReactPHP client. And now it’s time to start testing it.
He then walks through some of the steps to create the tests for the client, made a little more difficult by its asynchronous handling. He shows how to use Mockery to create tests that evaluate the results of the promises from the client, starting with a simple check on the return of a
version call. The post goes on to show testing for other parts of the client and includes all of the code and commands you'll need to execute them in your own environment.
