benchmarking macro v2: tests don't seem to execute the verify logic.

[gui1117]

I modify a benchmark to return an error or to panic in the verify branch, the tests are still successful.

This is because BenchmarkError::Weightless is consider a successful result and it is used in some setup of the benchmark
