Here is a github code <a href="https://github.com/pdalvi1893/kafka" rel="noopener noreferrer">link</a>, along with the necessary configuration files for kubernetes and node js application. </p> kind kubernetes kafka express Pankaj Dalvi Fri, 31 May 2024 17:32:53 +0000 https://dev.to/_pdalvi/unit-testing-in-strapi-46o1 https://dev.to/_pdalvi/unit-testing-in-strapi-46o1 <p>Strapi has been there around for quite some time now with a lot of organisations using it as their go to production framework for building cool apps using React , angular etc.</p> <p>However the more you search but less you find is about unit testing in strapi. There are lot of blogs that are termed as Unit testing in strapi however they are technically doing end to end testing using a sqlite database making reals hit to apis and generating a real output.</p> <p>The goal of this blog post is to shed some light on building unit tests for strapi, testing custom controller methods and services using unit tests.</p> <h3> Getting started </h3> <p>First and foremost create a sample strapi project. Below is the link for the same.</p> <ul> <li> <a href="https://docs.strapi.io/dev-docs/quick-start" rel="noopener noreferrer">Strapi Docs</a> - Strapi Getting Started Documentation.</li> </ul> <h3> Install Dependencies </h3> <p>Run the below command to install jest dependency<br> </p> <div class="highlight js-code-highlight"> <pre class="highlight plaintext"><code>npm install jest supertest --save-dev </code></pre> </div> <h3> Set-up Run comand </h3> <p>Add the below command in package.json file.
