Crate polkadot_primitives_test_helpers

A set of primitive constructors, to aid in crafting meaningful testcase while reducing repetition.

Note that dummy_ prefixed values are meant to be fillers, that should not matter, and will contain randomness based data.

Re-exports

pub use rand;

Structs

AlwaysZeroRng

A special Rng that always returns zero for testing something that implied to be random but should not be random in the tests

TestCandidateBuilder

Builder for CandidateReceipt.

Functions

dummy_candidate_commitments

Create candidate commitments with filler data.

dummy_candidate_descriptor

Create a candidate descriptor with filler data.

dummy_candidate_descriptor_bad_sig

Create a candidate descriptor with a bogus signature and filler data.

dummy_candidate_descriptor_v2

Create a v2 candidate descriptor with filler data.

dummy_candidate_receipt

Creates a candidate receipt with filler data.

dummy_candidate_receipt_bad_sig

Create a candidate receipt with a bogus signature and filler data. Optionally set the commitment hash with the commitments arg.

dummy_candidate_receipt_v2

Creates a v2 candidate receipt with filler data.

dummy_candidate_receipt_v2_bad_sig

Create a candidate receipt with a bogus signature and filler data. Optionally set the commitment hash with the commitments arg.

dummy_collator

Create a meaningless collator id.

dummy_collator_signature

Create a meaningless collator signature. It is important to not be 0, as we’d confuse v1 and v2 descriptors.

dummy_committed_candidate_receipt

Creates a committed candidate receipt with filler data.

dummy_committed_candidate_receipt_v2

Creates a v2 committed candidate receipt with filler data.

dummy_digest

Create meaningless dummy digest.

dummy_hash

Create meaningless dummy hash.

dummy_head_data

Create meaningless head data.

dummy_pvd

Create a meaningless persisted validation data.

dummy_signature

Creates a meaningless signature

dummy_validation_code

Create meaningless validation code.

dummy_validator

Create a meaningless validator id.

make_candidate

Create a meaningless candidate, returning its receipt and PVD.

make_candidate_v2

Create a meaningless v2 candidate, returning its receipt and PVD.

make_valid_candidate_descriptor

Create a new candidate descriptor, and apply a valid signature using the provided collator key.

make_valid_candidate_descriptor_v2

Create a v2 candidate descriptor.

resign_candidate_descriptor_with_collator

After manually modifying the candidate descriptor, resign with a defined collator key.

validator_pubkeys

Extracts validators’s public keys (ValidatorId) from Sr25519Keyring

zero_collator_signature

Create a zeroed collator signature.
