Today, the reportportal pre-4.0 released.
I’ve posted try reportportal before and I thought the tool looks helpful for us. I know of Allure2 which is close to this tool but report portal is a more pluggable reporting tool.
The tool provides to analyze test results using ML technology. We can see the feature’s video from https://www.youtube.com/watch?v=d2ekWI2exZ4 and it looks interesting. I guess the feature will be a handly trial to analysis test resuts.
We can run the tool with docker-composer easily and also, we can add test data via demo data section. Read http://reportportal.io/docs/Project-configuration . Thus, we can see some dashboard to confirm the behaviour.
Also, we can handle data via API and the portal also provide LDAP authentication, but it’s beta yet.
Reporting and management bugs with scenarios help developers and the tool also considers automated test scenarios with some testing framework.

Does it support parallel_rspec?
Does it support parallel_rspec?
They provide https://github.com/reportportal/agent-ruby and it has formatter for RSpec. You can customise the formatter to fit the tools, it looks. (Will the parallel_cucumber help you to extend the RSpec formatter?)
