Writing Script

When writing script to perform a batch job, a common bug that happens often is not verifying if a step has successfully completed. There are many instances where an error code is not caught and is subsequently overwritten by the following steps, resulting in a false positive result. Therefore, when writing a script task, the following tips would help to minimize this risk:

  1. Always verify that the result of the script is as expected. Such as checking error code or checking if a certain conditions have been met. This can be done at a number of places in the script where a certain change could impact the final outcome.
  2. Where a required condition was not met, log a message and exit with an appropriate non zero code. This will make sure the exit code will always be caught by the script task.
