Looks like a similar issue was referenced here: #219. In our case, expect in a finally without a return does not cause an ESLint issue.
describe("making a network call", () => {
it("Makes the correct call", () => {
const mySpy = jest.fn();
const callMySpyAsync = () => Promise.resolve().then(() => mySpy(5678));
callMySpyAsync(1234).finally(() => {
expect(mySpy).toHaveBeenCalledWith(1234);
});
});
});
