# How to write json test file?
Cause it's very hard to write generic json test files, each subdirectory should follow its own
convention. BUT all json files `within` same directory should be consistent.
### Test files should always contain a single test with input and output.
```json
{
input: ...,
output: ...
}
```
As a reference, please use trietests.

# Rlp tests guideline
Rlp can be tested in various ways. It can encode/decode a value or an array of values. Let's start with encoding.
Each operation must have field:
- `operation` - `append`, `append_list`, `append_empty` or `append_raw`
Additionally `append` and `append_raw` must additionally define a `value` field:
- `value` - data
Also `append_raw` and `append_list` requires `len` field
- `len` - integer
### Encoding Test Example
```json
{
"input":
[
{
"operation": "append_list",
"len": 2
},
{
"operation": "append",
"value": "cat"
},
{
"operation": "append",
"value": "dog"
}
],
"output": "0xc88363617183646f67"
}
```
