Overview

This PR adds tests for create_match_tournament covering bracket_id and round validation in the escrow contract. It asserts that duplicate bracket matches (same bracket_id + round + players) are rejected, and that a valid bracket creation succeeds and emits match/bracket_created. A new error variant is added in errors.rs to represent the duplicate-bracket rejection.

Changes

🧪 Match Validation Tests

• [ADD] contracts/escrow/src/tests/match_validation.rs

  • Test: creating two matches with the same bracket_id + round + players fails.
  • Test: valid bracket creation succeeds and emits match/bracket_created.

• [MODIFY] contracts/escrow/src/errors.rs

  • Adds the error variant returned when a duplicate bracket match is submitted, so the new test can assert on a specific error rather than a generic failure.

Verification Results

cargo test -p escrow match_validation

Both new tests exercise the duplicate-rejection path and the success/event path of create_match_tournament.

Acceptance Criteria	Status
Duplicate bracket_id + round + players is rejected	✅ Covered by new test in match_validation.rs
Valid bracket creation succeeds	✅ Covered by new test in match_validation.rs
match/bracket_created event is emitted on success	✅ Asserted in new test in match_validation.rs
