From 32f1d0ab5dae7f7b141d38d32088f803ed6e6cae Mon Sep 17 00:00:00 2001 From: Snider Date: Sun, 2 Nov 2025 22:29:17 +0000 Subject: [PATCH] Feature add tdd core tests (#22) * feat: Add TDD tests for core package Adds a new `tdd/` directory for TDD-style contract tests. Implements a comprehensive test suite for the `pkg/core` package, covering: - `New()` - `WithService()` - `WithName()` - `WithWails()` - `WithAssets()` - `WithServiceLock()` - `RegisterService()` - `Service()` - `ServiceFor()` - `MustServiceFor()` - `ACTION()` - `RegisterAction()` - `RegisterActions()` To support testing, a public `Assets()` method was added to the `Core` struct. * feat: Add TDD tests for e, io, runtime, and config packages Adds comprehensive TDD tests to the `tdd/` directory for the following packages: - `pkg/e` - `pkg/io` - `pkg/runtime` - `pkg/config` This significantly improves the test coverage of the project. To support testing the `runtime` package, the `newWithFactories` function was exported as `NewWithFactories`. The existing tests for the `config` package were moved from the `internal` package to the `tdd/` directory and adapted to use the public API. * fix: Update tdd tests for config, core, and runtime Updates the TDD tests for the `config`, `core`, and `runtime` packages to improve their coverage and correctness. - In `tdd/config_test.go`, the `TestIsFeatureEnabled` test is updated to use `s.Set` to modify the `features` slice, ensuring that the persistence logic is exercised. - In `tdd/core_test.go`, the `TestCore_WithAssets_Good` test is updated to use a real embedded filesystem with `//go:embed` to verify the contents of a test file. - In `tdd/runtime_test.go`, the `TestNew_Good` test is converted to a table-driven test to cover the happy path, error cases, and a case with a non-nil `application.App`. * fix: Fix build and improve test coverage This commit fixes a build failure in the `pkg/runtime` tests and significantly improves the test coverage for several packages. - Fixes a build failure in `pkg/runtime/runtime_test.go` by updating a call to an exported function. - Moves TDD tests for `config` and `e` packages into their respective package directories to ensure accurate coverage reporting. - Adds a new test suite for the `pkg/i18n` package, including a test helper to inject a mock i18n bundle. - Moves and updates tests for the `pkg/crypt` package to use its public API. - The coverage for `config` and `e` is now 100%. - The coverage for `crypt` and `i18n` has been significantly improved. --------- Co-authored-by: google-labs-jules[bot]
