I wonder if you’re using DDT at test case level. If yes, we already mentioned how the test result was counted in our documentation - Data-driven testing at the test case level.
"When running a test suite that uses variables and bindings at the test case level, the total number of executed test cases in test reports is the number of executed iterations.
An iteration is a test case executed with a test data row."
