Enum 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.
