No tests were executed

When I run `make test-benchmark` I get the following output:

```
mvn -Dtest=BenchmarkTest#checkHealth test
...
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.17:test (default-test) on project hobbit-java-sdk: No tests were executed!  (Set -DfailIfNoTests=false to ignore this error.) -> [Help 1]
