I have created a Jest test environment in which I mock a specific module:
const NodeEnvironment = require('jest-environment-node');
const { lumigo } = require('../../src/services/lumigo');
class TestEnvironment extends NodeEnvironment {
async setup() {
await super.setup();
jest.mock('../../src/services/lumigo');
lumigo.trace = jest.fn((func) => func);
}
async teardown() {
await super.teardown();
}
getVmContext() {
return super.getVmContext();
}
}
module.exports = TestEnvironment;
And I configure my test to use this test environment as follows:
/**
* @jest-environment ./tests/test-environment.js
*/
... rest of the test
However when I run my test I get the following error:
ReferenceError: jest is not defined
If at the top of my test environment file I try to add:
const jest = require('jest');
I get a warning that Jest is automatically in scope. Do not import "jest", as Jest doesn't export anything and the test still fails.
How can I use jest (for examples invocations to jest.mock) inside my test environment?
