test: update test suite for OZ v0.6.0 API and soroban-sdk 25

[aguilar1x]

Context

Depends on #5 (event migration). After all refactors the test suite in src/test.rs will need updates because:

1. Function signatures changed (transfer / transfer_from take MuxedAddress instead of Address for to)
2. The contract client generated by contractimpl now reflects the trait method signatures
3. Event assertions need to match the new #[contractevent] struct types if using soroban-test-helpers / stellar-event-assertion
4. soroban-sdk testutils API may have minor changes between 22.0.6 and 25.0.2

Expected changes

• Update all client.transfer(...) and client.transfer_from(...) calls to pass addresses in the new format
• If events are asserted, update assertions to match the new typed event structs (e.g., fungible::Transfer, fungible::Mint)
• Verify all 11 existing test cases pass:
  • test_basic_functionality
  • test_batch_mint
  • test_burn_functionality
  • test_pausable_functionality
  • test_allowance_and_transfer_from
  • test_comprehensive_validation
  • test_admin_functionality
  • test_address_validation
  • test_error_conditions
  • test_self_transfer_prevention
  • test_integer_only_operations
• Add any new tests required to cover trait-based behavior

Acceptance criteria

• cargo test passes with zero failures
• No #[allow(deprecated)] suppressions hiding test-time warnings
• Tests use soroban-sdk 25.0.2 testutils API correctly

Hello Team,

My Background
My name is Cristian, and I’m a passionate full-stack developer from Costa Rica 🇨🇷💻. I’m excited about the opportunity to contribute to your Stellar-based project during GrantFox!
I enjoy building web applications that combine clean user interfaces with solid back-end logic and reliable databases.

Experience
I have experience developing web applications using technologies such as React, .NET Core, SQL Server, and Firebase. I’ve worked on projects that include role-based systems, CRUD platforms, booking systems, and data-driven web apps.
While I’m still growing in Web3 and blockchain, I’m highly motivated to learn and apply these technologies, especially within the Stellar ecosystem.

I’m driven by the opportunity to improve my skills, collaborate with a talented team, and make a meaningful contribution to your project.

Thank you for considering my candidacy. I am excited about the opportunity to contribute to this project and create a positive impact. Please let me know if you have any questions or need additional information.

Hello, I’m a smart contract and full-stack developer actively contributing to open-source ecosystems. I’ve worked on 30+ projects across the ecosystem, with hands-on experience in Solidity, Cairo, Soroban, JavaScript, TypeScript, Rust, and building on the Stellar ecosystem. I’m passionate about delivering secure and scalable blockchain systems and would love the opportunity to support and contribute to this issue.

Hi team, I’d like to work on this issue.

I’ve maintained Soroban contract test suites through SDK upgrades and refactors, including client signature changes, typed #[contractevent] assertions, and testutils API updates—while keeping tests clean (no deprecated suppressions) and deterministic.

What I’ll deliver

Updated src/test.rs compatible with soroban-sdk 25.0.2
All client.transfer(...) / client.transfer_from(...) calls updated to use MuxedAddress for to
Event assertions updated to match new typed event structs (e.g., fungible::Transfer, fungible::Mint)
All 11 listed tests passing with cargo test (0 failures)
No #[allow(deprecated)] suppressions; tests use the correct testutils API
Any small additional tests needed to cover new trait-based behavior

Approach

Update client calls for new method signatures (MuxedAddress conversion helpers where needed)
Migrate event assertions to typed #[contractevent] structs using the project’s helpers
Adjust test setup/util usage for SDK 25.0.2 testutils changes
Run through all 11 tests, fix edge-case mismatches, and keep assertions precise

If assigned, I’ll open a PR that upgrades the full test suite cleanly and gets cargo test green with zero warnings hidden.

I will update every transfer and transfer_from call to accept MuxedAddress and align all event assertions to the new typed structs so cargo test passes with zero failures and no deprecated suppressions.

Hey maintainers! I'd like to take this issue.

I have experience maintaining Soroban contract test suites through SDK version upgrades — including client signature migrations, MuxedAddress conversions, typed #[contractevent] assertion updates, and soroban-sdk testutils API changes between minor versions.

For this issue I'll deliver:

All client.transfer(...) and client.transfer_from(...) calls updated to pass MuxedAddress for to per OZ v0.6.0 and soroban-sdk 25.0.2 signatures
Event assertions migrated to typed #[contractevent] structs (fungible::Transfer, fungible::Mint, etc.)
All 11 existing test cases passing with cargo test — zero failures, zero #[allow(deprecated)] suppressions
Any additional tests needed to cover new trait-based behavior
Clean testutils API usage aligned with soroban-sdk 25.0.2

I'm Anonfedora, I'm a Fullstack Blockchain Engr. I'm proficient in Rust (soroban), Rust serverside with Axum and tokio, Nestjs, epxressjs have vast experience in contributing and building on the Stellar ecosystem with the Rust using soroban's SDK.
I'm also good at comprehensively testing features.
ETA: < 6 hours from assignment

Hi! I reviewed the refactor and the test updates required after the event migration. I can update the test suite to match the new function signatures using MuxedAddress, adjust event assertions to the typed #[contractevent] structs, and ensure all existing tests pass with the soroban-sdk 25.0.2 testutils API. I’ll also add any missing tests needed for the trait-based behavior.
