test(contract): exhaustive test suite for group creation & retrieval (boundaries, scale, persistence)

[Akshola00]

Description

Build an exhaustive, adversarial test suite in contract/src/test.rs for group creation and the query functions (create, get, get_groups_by_creator). Go beyond happy-path — cover boundaries, scale, persistence, and event correctness.

Notes:

• IDs are BytesN<32> (BytesN::from_array); usage_count is u32; use setup_env().
• Duplicate creation panics ("group already exists"); missing group panics ("group not found").

Tests (required, contract/src/test.rs)

Core

• Successful creation — assert every field of AutoShareDetails (id, name, creator, usage_count, payment_token, empty members)
• Retrieve by ID via get
• get on non-existent group → panic ("group not found")
• Duplicate ID creation → panic ("group already exists")

Creator isolation & scale

• get_groups_by_creator returns all groups for one creator, in insertion order
• Empty Vec for a creator with no groups
• Multiple creators fully isolated — no cross-leakage
• Scale: one creator with many groups (e.g. 50) — all retrievable, order preserved
• Same name/payment_token reused across different IDs by the same creator — all coexist

Boundaries

• usage_count = 0 and usage_count = u32::MAX accepted and stored exactly
• Empty string name and a long name — stored faithfully
• IDs differing by a single byte are treated as distinct groups

Persistence & auth

• State persists across separate client calls (create, then get in a later call, same env)
• create requires creator auth — assert failure when the creator hasn't authorized (test without blanket mock_all_auths, using mock_auths/require_auth scoping)

Events

• created event emitted with exact (id, creator) topics/data
• Event count matches number of successful creates (no spurious events on panics)

Acceptance Criteria

• All categories above covered with precise assertions (no assert!(true) placeholders)
• Scale and boundary cases included; auth-failure path verified without global auth mocking
• Event payloads and counts asserted
• All tests pass (make test), builds to WASM (make build), no clippy warnings (make clippy), formatted (make fmt-check)

Dependencies

• ✅ create, get, get_groups_by_creator already implemented

Relevant files

• contract/src/test.rs (modified)
