Ans : OpKey provides various ways with help of which you can iterate the test case. One of iterating is using the data repository; for tests which require data parameterization. E.g. Login scenario testing with various data combinations. Other method is using FOR keyword. So in the example which you have asked- we will first fetch the number of rows in the webtable using the getrows function. Pass it to the FOR keyword and in between FOR and NEXT write steps which we wish to iterate.
