Code related feature

We also want to provide samples for the infix api

Following the things you need to do:

• copy CharSequenceAssertionsSample from fluent-api, adjust imports ...api.fluent... to ...api.infix... and ajdust the samples accordingly (always use the infix syntax, never the fluent).
• [ ]

Is there a way to switch to strict/eager assertion fail mode, so that one can use --pdb on demand?

Is your feature request related to a problem? Please describe.
Currently Snapper returns the error A snapshot does not exist when a snapshot does not exist. The user then has to go and set the UpdateSnapshots attribute and re-run the tests. This is cumbersome and an extra step that can be avoided to improve developer experience.

Describe the solution you'd like
If the environment

Let's make sure the matcher was called with supported parameters, fail fast otherwise.

There should be no need in console.error usage.
