I’m trying to get Jest setup and working with my Aurelia project. The Aurelia project was built from the CLI with Jest included. I have some components that rely on jQuery and SignalR that are causing the test suite to fail. I’ve tried some different methods to include jQuery in the Jest testing environment, but none of the methods I’ve found have been able to get the test suite to run successfully. Without attempting to include jQuery with Jest, running the tests throws this error:
I tried to include jQuery with my Jest setup by change my jest-pretest.ts file to look like this:
However, this still throws an error and doesn’t allow the test suite to run successfully:
test/jest-pretest.ts:22:8 - error TS2339: Property '$' does not exist on type 'Window & typeof globalThis'. 22 window.$ = window.jQuery = $; ~ test/jest-pretest.ts:22:19 - error TS2339: Property 'jQuery' does not exist on type 'Window & typeof globalThis'. 22 window.$ = window.jQuery = $;
If anyone has any experience working with SignalR, jQuery, and Jest together and has any ideas on what to try, please share!
Thanks in advance!
