  Sample application for Lightning Web Components and Salesforce Platform runtime and compute capabilities. Part of the sample gallery. Electric car manufacturer use case. Get inspired and learn best practices.

  

For the eCars app that we’re building, the activity will be to write an APEX test class for the PdfCreateService that we used in the prior session to call a Heroku microservice for generating PDF documents. The eCars code can be found at the linked Github repo and I have also included a link to the specific PdfCreateService class. If you have not gone through the exercise of pulling the code into a Salesforce Developer org or a scratch org, you’ll want to review some of the previous articles to take that pre-requisite step or follow the instructions in the Github repo on how to clone and deploy the application.

  Run Jest against LWC components in SFDX workspace environment

  

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.
