Try using ``value`` as a possible candidate improvement. Return True if self.current is canonically equal to value after the call, either bec

Return a tuple (new_args, new_kwargs) where all possible arguments have been moved to kwargs. new_args will only be non-empty if function has

Creates a strategies namespace for the given array module. * ``xp`` is the Array API library to automatically pass to the namespaced methods.

If any target observations have been made, attempt to optimise them all.

Recursively convert an object to json-encodable form. This is not intended to round-trip, but rather provide an analysis-ready format for obs

Throw an exception if the strategy is not valid. Strategies should implement ``do_validate``, which is called by this method. They sh

A trivial test function.

This has the same behaviour as lists, but returns sets instead. Note that Hypothesis cannot tell if values are drawn from elements are hashab

Returns a sort key such that "simpler" choice sequences are smaller than "more complicated" ones. We define sort_key so that x is simpler tha

Makes the settings profile registered under ``name`` the active profile. If no settings profile is registered under ``name``, raises

Merge two sequences of intervals into a single tuple of intervals. Any integer bounded by `x` or `y` is also bounded by the result.

Returns the shape resulting from broadcasting the input shapes together. Raises ValueError if the shapes are not broadcast-compatible

Generates values by drawing from ``args`` and ``kwargs`` and passing them to the callable (provided as the first positional argument) in the a

Deserialize a bytestring to a tuple of choices. Inverts choices_to_bytes. Returns None if the given bytestring is not a valid serialization

A decorator which sets the name, signature and docstring of the function passed into it.

Returns a string that is stable across multiple invocations across multiple processes and is prone to changing significantly in response to mi

Register a settings object as a settings profile, under the name ``name``. The ``parent`` and ``kwargs`` arguments to this method are

Returns a pair of a tuple and a dictionary which would be equivalent passed as positional and keyword args to the function. Unless function has

Finds a (hopefully large) integer such that f(n) is True and f(n + 1) is False. f(0) is assumed to be True and will not be checked.

Tests whether the feature named ``name`` should be enabled on this test run.

Returns ``True`` if ``f`` represents a test function that has been defined with Hypothesis. This is true for: * Functions decorated with

This function can be used to pass multiple results to the target(s) of a rule. Just use ``return multiple(result1, result2, ...)`` in your rule.

Return a strategy which only generates None. Examples from this strategy do not shrink (because there is only one).

This strategy never successfully draws a value and will always reject on an attempt to draw. Examples from this strategy do not shrink (becau

Mark ``key`` as pinned (with the given value). That is, it may not be evicted until ``unpin(key)`` has been called. The same key may be

Mark this example as an expected failure, similarly to :obj:`pytest.mark.xfail(strict=True) <pytest.mark.xfail>`. Expected-failing ex

Write a call to `func` with explicit and implicit arguments. >>> _write_call(sorted, "my_seq", "func") "builtins.sorted(my_seq, key=func, rev

Adds ``f`` as a callback for |observability|. ``f`` should accept one argument, which is an observation. Whenever Hypothesis produces a n

Return a multi-line string describing the passed run statistics. `stats_dict` must be a dictionary of data in the format collected by `hypoth

A strategy for strings accepted by the given context-free grammar. ``grammar`` must be a ``Lark`` object, which wraps an EBNF specification.

Returns the settings profile registered under ``name``. If no settings profile is registered under ``name``, raises |InvalidArgument|

Set intersection for lists of intervals.
