   > As we add support for more Spark expressions, I can see that it makes 
sense to see if these expressions are already implemented in DataFusion, but we 
would still have to implement Spark-specific tests in Comet and then determine 
if the DataFusion expression is sufficient. If not, we then have to implement 
our own custom version.
   
   
   Thanks @andygrove for the review. Basically the idea of this test to show 
how much coverage we currently have in Comet for Spark builtin functions. 
   I supposed it would be interesting to have the following info per each 
builtin function:
   - is function supported by Comet?
   - If its not, is function supported by DataFusion directly or we need to 
send a PR to DF?
   - Sometimes function is supported by DF but it gives a wrong result in Comet 
comparing to Spark
   
   Having info we can later generate the coverage .MD dynamically instead of 
static one.
