Initial note¶

After hearing Will describe the procedures for me, he suggested that I focus my tests on update-soil-health, as that is the wrapper function for all of the other procedures. He also sent me the data for his soil-health change calculations, and I've been trying to understand how it all works. I think I have some basic understanding of how it works, but I do have several questions:

• what are m_b and m_w? in the model they don't appear to be constants, so are they calculated? is that why they aren't used in the example cases at the bottom of the spreadsheets?
• are the functionalities all implemented? i.e can I even write tests to begin with? some of these procedures look incomplete
• are the procedures stochastic or deterministic? should I be looking for a range of possible soil health changes or a specific value according to a function?

Structure of the tests¶

• For simplicity's sake, all tests will be run with one firm and one patch of land
• The first test I do will be a test of the soil health increase and decrease with respect to labor; I'll keep firm competency constant and run a loop increasing the amount of labor, and check to see if the change in soil health is what it should be
• For the decreasing portion of the test, I'll be sure to include tests that take the health to zero, to make sure the health does not drop below 0
• I'll also run a similar test where I vary the firm competency but keep labor constant to see if that effect is what it should be
