Self recurring class to create test records in Salesforse object

While working on Round Robin Incidents Assignment Routine for BMC Remedyforce we've built a tool to auto create test Incident records. This tool creates new record every one minute simulating real environment.

After minor modifications the same solution could be used for similar purposes to simulate creating records in standard or custom from SFDC UI. Below we provided example of self recurring class to create test Contact records.

The code has comments however please feel free to Contact Us if you have any questions.

SFDC Developer Console commands to use with AutoContactsCreator class

To execute self recurring class
AutoContactsCreator autoCrCon = new AutoContactsCreator();
autoCrCon.StartJob();

To abort self recurring class
AutoContactsCreator autoCrCon = new AutoContactsCreator();
autoCrCon.deleteJob();
Note: You also can abort the job manually here Setup -> Jobs -> Scheduled Jobs

Helpful command to DELETE all previously created by self recurring class test records
DELETE [SELECT id FROM Contact WHERE LastName LIKE 'AutoContact%'];
