Context:
Currently we use a model from a file, to improve readability and be more flexible on actual model xml changes we should build a model needed for the test using the model builder.
SeeĀ https://github.com/camunda/camunda-optimize/pull/1377#discussion_r355495135
We do something similar for the report rest ITs, so perhaps we could also remove the file loading strategy from those tests too
ATs:
- No longer loading BPMN xml from files for EventBasedProcessRestServiceIT test setup
- No longer loading BPMN xml from files for ReportRestServiceIT test setup
- We no longer need the files in our IT resources
