* snapshot testing with verify * formatting * add back old serialization tests * pass verify * use json correctly * formatting * Don't use Quibble and order ourselves because ordering doesn't matter * whitespace on snapshot * Better json diffing? Quibble is back * add common project * add object unit tests to see how verify would work * format * move random exes to new solution folder * update lock files
