Tests are required to make sure the application we have built works correctly. To enable testing, you need to create the testbench sub-folder with the testAggregator.py file in the aggregator folder. The testAggregator.py file should contain the following code:
from analytic import aggregatorif __name__ == "__main__": a = aggregator() assert a.sum('{"timeseries": [[1501664960967,12,3],[1501664961973,48,3]]}') == {"result": 60}
