title	Title of test run (or plan) to create.
runId	TestRail run id. Update a specific run instead of creating a new run.
useLatestRunId	true if updating latest run id instead of creating a new run. Defaults to false.
version	Version tested, if required by TestRail instance.
createTestPlan	If true, creates a test plan to which runs are added. Runs within are appended with the browser name.

strictCaseMatching	false to NOT throw an error if a test case found is not apart of the suite. Defaults to true.
skippedStatusId	A custom status id assigned to skipped tests. If not assigned, skipped tests will be marked as status 4.

casesFieldFilter	A {key: value} object to filter cases added to the test run, e.g. {'priority_id': 1, 'type_id': 2}. Values should be taken from TestRails. Running with empty value or with missing closeTestRailRun option will return a full list of cases. NOTE 1: if you use multiple key:value pairs in the filter object it will work as AND conditions. NOTE 2: casesFieldFilter takes into account only if includeAll=false
