I'm calling
TEST-EHR>DO ##class(TestCoverage.Manager).RunTest(,"/nodelete",.tCoverageParams)

my tCoverageParams are the following.  

TEST-EHR>zw tCoverageParams
tCoverageParams("CoverageClasses")=$lb("modul.ehr.host.check.CheckOperation","modul.ehr.host.docadd.EHRAddOrUpdateOperation")
tCoverageParams("CoverageDetail")=3
tCoverageParams("SourceNamespace")="TEST-EHR"
tCoverageParams("Timing")=0
