# HDK Unit Testing This crate provides a library of [mocked hdk functions](src/mock_hdk.rs) to help with unit testing your zome functions. ## usage In your tests, instantiate a mutable `MockHdkT` object and pass a mutable reference of this into the mocked hdk functions. ```rust let mut mock_hdk = MockHdkT::new(); let mock_hdk_ref = &mut mock_hdk; ``` All mocked functions take `mock_hdk_ref` as an input as well as the expected input and output of the called hdk function. ```rust use hdk_unit_testing::mock_hdk::*; mock_create( mock_hdk_ref, expected_input, expected_output, ); ``` See an example usage in [Acorn](https://github.com/h-be/acorn/blob/c877964162346864bbe2995fec951d83182b518c/dna/tests/src/profiles/profile.rs#L17-L29).
