Hi, The v8_simple_wasm_*_fuzzer binaries exist just to reproduce issues found by libFuzzer <https://llvm.org/docs/LibFuzzer.html>-based fuzzers in Chromium. These binaries don't produce any output other than crashing or not crashing. You can take a look at https://github.com/v8/v8/blob/master/test/fuzzer/README.md#changes-to-chromium on how to run the fuzzers in Chromium.
The tests run by fuzzer/testcfg.py are supposed to test the fuzzer code, not to start fuzzing itself.
