Module prelude

Expand description

Common zebra_test types, traits, and functions.

Re-exports§

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;.

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.

BoxedStrategy: A boxed Strategy trait object as produced by Strategy::boxed().
Just: A Strategy which always produces a single value value and never simplifies.
ProptestConfig: Configuration for how a proptest test should be run.
SBoxedStrategy: A boxed Strategy trait object which is also Sync and Send, as produced by Strategy::sboxed().
Stdio: Describes what to do with a standard I/O stream for a child process when passed to the stdin, stdout, and stderr methods of Command.

TestCaseError: Errors which can be returned from test cases to indicate non-successful completion.

Arbitrary: Arbitrary determines a canonical Strategy for the implementing type.
Rng: User-level interface for RNGs
RngCore: Implementation-level interface for RNGs
Strategy: A strategy for producing arbitrary values of a given type.

any: Generates a Strategy producing Arbitrary values of A. Unlike arbitrary, it should be used for being explicit on what A is. For clarity, this may be a good idea.
any_with: Generates a Strategy producing Arbitrary values of A with the given configuration arguments passed in args. Unlike arbitrary_with, it should be used for being explicit on what A is. For clarity, this may be a good idea.
