Instantiate a @salesforce/core test context. This is automatically created by const $$ = testSetup() but is useful if you don't want to have a global stub of @salesforce/core and you want to isolate it to a single describe.

Note: Call stubContext in your beforeEach to have clean stubs of @salesforce/core every test run.

const $$ = instantiateContext();

beforeEach(() => {
$$.init()
});

afterEach(() => {
$$.restore();
});
