HPCC Systems maintains a robust testing environment, composed of two systems, the Smoketest and the Overnight Build and Test System (OBT). These systems are used for regression testing and ensuring that the source code of the HPCC Systems platforms generates accurate results. Files from these systems are operated automatically throughout each day, so it is crucial that they are on par with modern computing standards. These systems were developed over 7 years ago and thus have some features that are not up to date in the current landscape. This primarily relates to the Python files, developed in Python 2, a version no longer supported. The main objective for this project is to convert the Python files from the Smoketest and OBT
from Python 2 to Python 3. There are tools such as 2to3 that automate the conversion process by changing segments of codes based on pre-existing conditions in its algorithm. This tool is not enough to ensure a healthy conversion, which is why manual review and testing are a mandatory part of this project as well. In addition, another principal goal is a clean-up of both the Python and Bash files for the testing systems. This involves removing commented code that does not serve a purpose to the file anymore, unused variables and uncalled functions. This also entails reducing duplicate code through creating functions, default parameters and constants. Finally, all modifications made to a file are documented in a corresponding text file. This is done to ensure that if any issues come up the base implementation can be retrieved for investigation. This also provides the opportunity for an original feature to be utilized if needed in a future version.
