Reseting datasource to first row

Hello,   I have a functional test in which I am using same datasource step in two different loops. First loop is to create a data, second loop to validate. However I am unable to loop the datasourc...

    Hi,

     

    You're only missing a second Datasource test step.

     

    Insert a new Datasource step either before Step 5 for Step 6.  Call the step itself something different, like "Datasource - validate"  I suspect before Step 6 is the place.

     

    Then update DataSourceLoop2 to point at the "Datasource - valdidate" datasource step.

     

    Why did it not work?  The Datasource step keeps track of the current row whilst the testing is running.  When the test runs again, it resets, but it doesn't reset in the context of the same test running.  That's why the second loop is on the last row.

Hello,

 

sorry for just a brief description, will try to explain more:

 

I have a two separate loops, one after another, no nesting. Something like ChrisAdams's second example, but with just one datasource.

 

This my test case (screenshot_61.jpg):

- Step1: GetList (REST request)

- Step2: DataSource (from JSON response of Step1 (GetList) - 73rows)

-- Step3: CreateData (REST request in loop. uses ${DataSource#data}. it gets executed 73 times.)

-- Step4: DataSourceLoop1 (Data Source Step: DataSource, Target Step: CreateData)

- Step5: GetAnotherList (REST request.)

-- Step6: ValidateItemInList (Assertion. uses ${DataSource#data} and validates against GetAnotherList.response. it gets executed only 1 time (for last row of DataSource)) 

-- Step7: DataSourceLoop2 (Data Source Step: DataSource, Target Step: ValidateItemInList)

 

So the problem is step 6/7. I would expected the loop for that datasource go again from row 1 to row 73, but it only executes the 73th row.

 

Transaction log: Screenshot_62.jpg .

 

P.S. I have set testcase to continue on errors.

    Thanks, that explains it. So the "RestartOnRun" param reffers to "run" of test case. Was hoping that it could somehow be solved with one data source. Having and maintaining two data sources that holds the same data, same columns, same props... seems like a copy&paste work 😞

     

    But I would still like to ask whether there is a way to set current data source row from Groovy Script. In API docs I can see two public methods of WsdlDataSourceTestStep regarding rows - setEndRow and setStartRow, but that only limit datasource range. Is there some way to set current row? I am not sure whether I read the right/actual API docs (https://support.smartbear.com/readyapi/apidocs/pro/DefaultPackage/WsdlDataSourceTestStep.html), because it links to lot of non-existing 404 pages.

      Ok I was playing with that and it's possible by ds.SetStartRow() and then calling ds.restart(testRunner,context)  🙂 Like that it can work even with one data source.
