🎓 Usage

Basic

A basic assertion.

>>> import conjecture
>>> assert 5 == conjecture.has(lambda v: v < 10)
>>> assert 5 == conjecture.has(lambda v: v > 10)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AssertionError

Combined conjectures

Matching all conditions.

>>> import conjecture
>>> assert 5 == conjecture.has(lambda v: v <= 5) & conjecture.has(lambda v: v => 5)
>>> assert 6 == conjecture.has(lambda v: v <= 5) & conjecture.has(lambda v: v => 5)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AssertionError
>>> assert 5 == conjecture.all_of(
...     conjecture.has(lambda v: v <= 5),
...     conjecture.has(lambda v: v => 5)
... )
>>> assert 6 == conjecture.all_of(
...     conjecture.has(lambda v: v <= 5),
...     conjecture.has(lambda v: v => 5)
... )
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AssertionError

Matching any conditions.

>>> import conjecture
>>> assert 0 == conjecture.has(lambda v: v == 5) | conjecture.has(lambda v: v == 0)
>>> assert 5 == conjecture.has(lambda v: v == 5) | conjecture.has(lambda v: v == 0)
>>> assert 6 == conjecture.has(lambda v: v == 5) | conjecture.has(lambda v: v == 0)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AssertionError
>>> assert 5 == conjecture.any_of(
...     conjecture.has(lambda v: v == 5),
...     conjecture.has(lambda v: v == 0)
... )
>>> assert 6 == conjecture.any_of(
...     conjecture.has(lambda v: v == 5),
...     conjecture.has(lambda v: v == 0)
... )
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AssertionError

Negation

A negative assertion.

>>> import conjecture
>>> assert 5 != conjecture.has(lambda v: v == 10)
>>> assert 5 == ~conjecture.has(lambda v: v == 10)
>>> assert 10 == ~conjecture.has(lambda v: v == 10)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AssertionError
