1. A computer-implemented method for determining correctness of a job plan in a stream processing application executed by a stream application framework, comprising: receiving a job plan for a stream processing application, the job plan comprising at least a first directed sequence of processing elements, wherein each processing element in the directed sequence is configured to generate an output data for an input data; identifying based on predetermined criteria, a second directed sequence of processing elements, similar to the first directed sequence; processing a set of input data in both the first directed sequence and the second directed sequence; and upon determining that the output of processing the set of input data in the second directed sequence is inconsistent with the output of processing the set of input data in the first directed sequence: identifying, from the first directed sequence and the second directed sequence, an invalid directed sequence, wherein processing the invalid directed sequence does not result in correct results; and performing at least one corrective action to address the invalid directed sequence.
