More information on testing HTTP callout methods and code samples can be found at the APEX Developer Guide as well as the APEX recipes Github repo.

When first starting out doing development, I did a lot of copy-pasting and editing existing code. There is no shame in this; it’s all part of the learning process. Luckily, in the APEX Recipes Github repository, we can find some APEX Recipes with bite-sized snippets of code for almost everything that you might need. The code samples found here are also “production quality,” so it would be a useful exercise to review and compare it with any existing code you’ve written to gain some insights into what Salesforce considers best practices.

For those who are familiar with testing in Javascript but not in APEX or vice-versa, here are some key things to note. The Apex language comes with system methods for writing apex unit tests classes. For JavaScript, there are a number of different testing frameworks but Salesforce recommends using Jest for Lightning Web Components and LWC OSS because of its popularity, ease-of-use, and open-source framework. Jest for Lightning Web Components is available at the sfdx-lwc-jest Github repo. The following table draws some comparisons between the frameworks.
