Adding fuzzer to verify fuzzService functionality
Adding a TestService which crashes and adding a fuzzer to fuzz this
service. Whenever fuzzService is modified, this fuzzer should be
run. It usually crashes in first few seconds.
This fuzzer won't run on the infra
Test: m test_service_fuzzer_should_crash && out/host/linux-x86/fuzz/x86_64/test_service_fuzzer_should_crash/test_service_fuzzer_should_crash
Test: m test_service_fuzzer_should_crash && adb sync data && adb shell /data/fuzz/x86_64/test_service_fuzzer_should_crash/test_service_fuzzer_should_crash
