Returns a strategy which generates floats. - If min_value is not None, all values will be ``>= min_value`` (or ``> min_value`` if ``exclude

Register and un-register a type for st.from_type(). This is not too hard, but there's a subtlety in restoring the previously-registered strat

Run steps from each pass in ``passes`` until the current shrink target is a fixed point of all of them.

Run the full set of shrinks and update shrink_target. This method is "mostly idempotent" - calling it twice is unlikely to have any e

Returns a strategy which generates instances of :class:`python:bool`. Examples from this strategy will shrink towards ``False`` (i.e. shrinki

Return a strategy which only generates ``value``. Note: ``value`` is not copied. Be wary of using mutable values. If ``value`` is the result

The name of the current settings profile. For example: .. code-block:: python >>> settings.load_profile("myprofile")

Report this value for the minimal failing example.

Remove all keys, regardless of their pinned status.

Returns the minimal example from the given strategy ``specifier`` that matches the predicate function ``condition``.

Convert the result of running this test into either an Overrun object or a ConjectureResult.
