block.test.ts

TLDR

This file contains unit tests for the block module. It verifies that the createPatchesFromBlocks function correctly generates patches based on two blocks. The tests also check the behavior of adding and removing fields, as well as updating properties of the main object and reverting them back.

Methods

createPatchesFromBlocks

This method takes two blocks as input and generates patches based on their differences. It is used to compare and update blocks in the block module.
