# Test format: SSZ uints
|
|
|
|
|
|
|
|
|
|
SSZ supports encoding of uints up to 32 bytes. These are considered to be basic types.

## Test case format
|
|
|
|
|
|
|
|
|
|
```yaml
|
2019-04-12 13:02:36 +00:00
|
|
|
type: "uintN" -- string, where N is one of [8, 16, 32, 64, 128, 256]
|
|
|
|
|
valid: bool -- expected validity of the input data
|
|
|
|
|
value: string -- string, decimal encoding, to support up to 256 bit integers
|
|
|
|
|
ssz: bytes -- string, input data, hex encoded, with prefix 0x
|
|
|
|
|
tags: List[string] -- description of test case, in the form of a list of labels
|

## Condition
|

|
|
|

2019-04-12 13:02:36 +00:00
|
|
|
Two-way testing can be implemented in the test-runner:
|
|
|
|
|
- Encoding: After encoding the given input number `value`, the output should match `ssz`
|
|
|
|
|
- Decoding: After decoding the given `ssz` bytes, it should match the input number `value`
|
