Represents an execution of a step that belongs to a job. The job execution this step execution belongs to can be accessed via getJobExecution(). If a pipeline is used to implement a step this step execution is available in the pipeline dictionary under the key 'JobStepExecution'. If a script module is used to implement a step this step execution is available as the second parameter of the module's function that is used to execute the step, e.g.:

 ...
 exports.execute( parameters, stepExecution)
 {
      ...
      var jobExecution = stepExecution.getJobExecution();
      ...
 }
