Experience Builder Developer Edition: Tests fail to run

RYANCARL — Thu, 15 Jul 2021 01:10:10 GMT

Hello all,

Not sure if there is a GitHub repo that I can submit an issue to, but I have noticed that in the 1.4 release of the ArcGIS Experience Builder Developer Edition the command npm run test will fail with the error:

my-pc ~/Desktop/ArcGISExperienceBuilder/client $ npm run test > exb-client@1.4.0 test C:\Users\user\Desktop\ArcGISExperienceBuilder\client > jest --runInBand FAIL your-extensions/widgets/simple/tests/simple-widget.test.tsx ● Test suite failed to run TypeError: global.systemRegister is not a function at SystemJS.Object.<anonymous>.System.register (dist/jimu-core/react.js:18:16) at Object.<anonymous> (dist/jimu-core/react.js:26:12) at Object.<anonymous> (node_modules/@wojtekmaj/enzyme-adapter-react-17/src/ReactSeventeenAdapter.js:2:1) at Object.<anonymous> (node_modules/@wojtekmaj/enzyme-adapter-react-17/src/index.js:2:18) at Object.<anonymous> (jimu-for-test/setup-jest.js:3:17) Test Suites: 1 failed, 1 total Tests: 0 total Snapshots: 0 total Time: 11.737 s npm ERR! code ELIFECYCLE npm ERR! errno 1 npm ERR! exb-client@1.4.0 test: `jest --runInBand` npm ERR!

After looking around the community board it looks like someone noticed this issue a little while ago and mentions the fix here .

It seems like the fix for this is to adjust the client/jimu-for-test/setup-jest.js like the following code:

// require('jest-fetch-mock').enableMocks() // const Enzyme = require('enzyme'); // const Adapter = require('@wojtekmaj/enzyme-adapter-react-17') // const { System } = require('systemjs'); // Enzyme.configure({ adapter: new Adapter() }); // global.systemRegister = System.register; require('jest-fetch-mock').enableMocks() const { System } = require('systemjs'); global.systemRegister = System.register; const Enzyme = require('enzyme'); const Adapter = require('@wojtekmaj/enzyme-adapter-react-17') Enzyme.configure({ adapter: new Adapter() });

The commented out code is the code that is originally in the file and the code that is bellow is the adjustment to make tests work.

How has everyone been testing their code?
