### Special handling of counter reset hints in native histograms
Native histograms as part of `<points>` may or may not contain an explicit
`counter_reset_hint` property. If a `counter_reset_hint` is provided
explicitly, the counter reset hint of the histogram is tested to have the
provided value (`unknown`, `reset`, `not_reset`, or `gauge`). However, if no
`counter_reset_hint` is specified, the `counter_reset_hint` is not tested at
all (rather than testing for the usual default value `unknown`).
### `expect string`
This can be used to specify that a string literal is the expected result.
