Benchmark test cases for DFT program or VASP?

[Alford]

I am trying to build my workflow of using DFT to predict properties of some materials, but I am not sure if I do it all right, so I think there might be some benchmark test cases for the DFT program, but it seems there are only some test cases for testing if the installation is right. I am not looking for a database of material properties, but a complete test case that includes every step of how to build the model.
My question is:
where should I find a benchmark test case of my workflow?
And if it is not possible to get a benchmark test case for all DFT programs, a test case just for VASP would be also helpful.

In the recent versions of vasp, you can find a testsuite provided.
