Enum proptest::test_runner::TestError

source · [−]

pub enum TestError<T> {
    Abort(Reason),
    Fail(Reason, T),
}

Expand description

A failure state from running test cases for a single test.

Variants

`Abort(Reason)`

The test was aborted for the given reason, for example, due to too many inputs having been rejected.

`Fail(Reason, T)`

A failing test case was found. The string indicates where and/or why the test failed. The T is the minimal input found to reproduce the failure.
