Just tests/ is shorter and simpler.
The json_ prefix does not add any additional information since the parent folder is already vlib/json .

I've renamed that test as a workaround in 462f186 . It has nothing to do with this PR.

I separated the name to make it easier to merge x.json2, x.json2.decode2 and json. If you prefer, I can divide it into 3 folders like tests/json, tests/encoder, tests/decoder. What do you think?

I think that they should stay as they are in the top level, or use test/ folder.
