Paralellism
Every CI servers tends to address this differently (parallel, distributed, build matrix). Some of it is just marketing, and some is just nuance. For this table, parallel means that tasks can be run concurrently on the same machine, distributed means that tasks can be scaled horizontally, on multiple machines
How to split tests in parallel in the optimal way with Knapsack Pro

Yes

Via easy Yaml config file, limited by the specs of the machine you have purchased

Yes

Yes

Pipelines are defined using an Yaml config file and allow for great flexibility in defining what each step of the process does.

Reports
Reports are about the abilty to see specific reports (like code coverage or custom ones), but not necesarily tied in into a larger dashboard.

Yes

Additional notes

CodeShip Pro gives you a lot more flexibility when defining your CI/CD process, plus you get your own AWS instance, so your build doesn't run on a shared server (this can be important for HIPAA or GDPR compliance, etc).
