"Modified WRF code must be run through the WRF Testing Framework (WTF). The WTF is designed to build and test WRF compilation and running, and to analyze test results for versions of the model with new modifications. The WTF is described here: WRF Software Testing. The WTF materials can be obtained from the WRF users download page at: WRF Testing Framework."
