Module prelude

Re-exports the most commonly-needed APIs of proptest.

This module is intended to be wildcard-imported, i.e., use proptest::prelude::*;. Note that it re-exports the whole crate itself under the name prop, so you don’t need a separate use proptest; line.

In addition to Proptest’s own APIs, this also reexports a small portion of the rand crate sufficient to easily use prop_perturb and other functionality that exposes random number generators. Please note that this is will always be a direct reexport; using these in preference to using the rand crate directly will not provide insulation from the upcoming revision to the rand crate.

Re-exports

pub use crate::arbitrary::any;

pub use crate::arbitrary::any_with;

pub use crate::arbitrary::Arbitrary;

pub use crate::strategy::BoxedStrategy;

pub use crate::strategy::Just;

pub use crate::strategy::SBoxedStrategy;

pub use crate::strategy::Strategy;

pub use crate::test_runner::Config as ProptestConfig;

pub use crate::test_runner::TestCaseError;

Modules

prop

Re-exports the entire public API of proptest so that an import of prelude allows simply writing, for example, prop::num::i32::ANY rather than proptest::num::i32::ANY plus a separate use proptest;.

Macros

prop_assert

Similar to assert! from std, but returns a test failure instead of panicking if the condition fails.

prop_assert_eq

Similar to assert_eq! from std, but returns a test failure instead of panicking if the condition fails.

prop_assert_ne

Similar to assert_ne! from std, but returns a test failure instead of panicking if the condition fails.

prop_assume

Rejects the test input if assumptions are not met.

prop_compose

Convenience to define functions which produce new strategies.

prop_oneof

Produce a strategy which picks one of the listed choices.

proptest

Easily define proptest tests.
