pub struct TestRunner { /* fields omitted */ }
State used when running a proptest test.
Create a fresh TestRunner
with the given configuration.
Returns the RNG for this test run.
Create a new, independent but deterministic RNG from the RNG in this
runner.
Returns the configuration of this runner.
Run test cases against f
, choosing inputs via strategy
.
If any failure cases occur, try to find a minimal failure case and
report that. If invoking f
panics, the panic is turned into a
TestCaseError::Fail
.
If failure persistence is enabled, all persisted failing cases are
tested first. If a later non-persisted case fails, its seed is
persisted before returning failure.
Returns success or failure indicating why the test as a whole failed.
Run one specific test case against this runner.
If the test fails, finds the minimal failing test case. If the test
does not fail, returns whether it succeeded or was filtered out.
This does not honour the fork
config, and will not be able to
terminate the run if it runs for longer than timeout
. However, if the
test function returns but took longer than timeout
, the test case
will fail.
Update the state to account for a local rejection from whence
, and
return Ok
if the caller should keep going or Err
to abort.
Increment the counter of flat map regenerations and return whether it
is still under the configured limit.
