A test that can never fail

Why does this test always pass, even when no "Overdue" invoice exists?

test('flags overdue invoices', () => {
  const invoices = getInvoices()
  invoices.filter((i) => i.status === 'Overdue').forEach((i) => {
    expect(i.reminderSent).toBe(true)
  })
})

A.If the filter returns no items, no assertion runs and the test passesB.forEach runs asynchronously, so Jest misses the assertions insideC.toBe(true) always passes when the property is undefinedD.Jest skips tests that use filter() on arrays of objects
