Starting from scratch and following https://github.com/eclipse/microprofile-metrics/blob/master/tck/running_the_tck.asciidoc was more complicated than expected.
So next attempt was to look at https://github.com/smallrye/smallrye-metrics/tree/master/testsuite/rest-tck.
Steps were following:
- Check if it can run with WF 14 using
mvn test -Dversion.wildfly=14.0.0.Final - Move from WildFly servlet distribution to full WildFly 14 distribution
- Move to WildFly 15 distribution which includes MP Metrics
MP Metrics REST TCK passes, warnings in log.
- Repo: https://github.com/rsvoboda/smallrye-metrics/tree/wf15TckExperiment
- Command:
mvn clean test -Dversion.wildfly=15.0.0.CR1 -Dtest.url=http://localhost:9990 -Dmaven.test.redirectTestOutputToFile=true
