Walkthrough

This change introduces a comprehensive set of new unit tests for the settings-related stores in the application. The tests focus on verifying correct behaviors for network and orderbook management, derived store outputs, serialization and deserialization of settings, and various edge cases. The modifications are limited to test files, with no alterations to the core logic or exported entities of the stores themselves. Test setup improvements are also included to ensure isolation between test cases.

tauri-app/src/lib/stores/settings.ts (6)

285-286: Good improvement to test setup

Adding these lines to reset activeNetworkRef and activeOrderbookRef before each test helps prevent state leakage between tests, ensuring proper test isolation.

---

342-351: Well-implemented edge case test

This test properly verifies that active accounts are reset when the accounts setting becomes undefined, which is an important edge case to cover.

---

391-549: Great addition of comprehensive Network and Orderbook tests

This test suite thoroughly covers the network and orderbook management functionality including:

• Reset behaviors when settings become undefined
• Reference initialization with first available option
• Network filtering of orderbooks
• Incompatible network handling
• Required settings validation

The tests are well-structured with clear assertions and good test isolation.

---

551-602: Good coverage of derived store behaviors

These tests effectively verify that derived stores like subgraphUrl, accounts, and activeAccounts produce the expected outputs under various conditions, which is crucial for ensuring the reactive UI behaves correctly.

---

604-635: Thorough validation of serialization/deserialization logic

This test suite properly verifies:

• Boolean serialization for activeOrderStatus
• Default value handling for hideZeroBalanceVaults
• String handling for orderHash

This ensures the persistence layer correctly maintains the expected data types.

---

637-671: Robust handling of edge cases

These tests cover important edge cases:

• Invalid JSON handling in settings
• Filtering of active account items when extra accounts are present

This improves the robustness of the application when facing unexpected input.
