# BLS tests A test type for BLS. Primarily geared towards verifying the *integration* of any BLS library. We do not recommend rolling your own crypto or using an untested BLS library. The BLS test suite runner has the following handlers: - [`aggregate_verify`](./aggregate_verify.md) - [`aggregate`](./aggregate.md) - [`fast_aggregate_verify`](./fast_aggregate_verify.md) - [`sign`](./sign.md) - [`verify`](./verify.md) *Note*: Signature-verification and aggregate-verify test cases are not yet supported.
