Hi! My name is Michael. I sometimes write code :) 2023-12-12T20:56:29.000Z https://www.graymatterdeveloper.com/ Michael Yarichuk Hexo https://www.graymatterdeveloper.com/2023/12/12/works-on-my-machine/ 2023-12-12T20:56:29.000Z 2023-12-12T20:56:29.000Z

<p>Oh, but it works on my machine! Today, I found myself staring at the monitor, adding logs and reviewing existing ones, carefully

<p>Ever found yourself deep in unit tests, only to realize you need to mock an HttpClient? Yep, we’ve all been there. There are many ways

<p>Early in my career, I joined a team that had extensive test coverage—hundreds of unit and functional tests with reasonable mocks.

<p>You’ll never need memory dumps. Until you do. And then it’s the only tool that saves you.</p> <p>In our microservice architecture, we
