This is the main important test suite. - Moving forwards, add unit tests next to the relevant code. +## Writing Integration Tests + +Integration tests are organized by language and tool type, following this structure: + +``` +integrationtests/ + ├── languages/ + │ ├── common/ - Shared test framework code + │ │ ├── framework.go - TestSuite and config definitions + │ │ └── helpers.go - Testing utilities and snapshot support + │ └── go/ - Go language tests + │ ├── internal/ - Go-specific test helpers + │ ├── definition/ - Definition tool tests + │ └── diagnostics/ - Diagnostics tool

for testing + └── with_errors/ - Workspace variant with intentional errors +``` + +Guidelines for writing integration tests: + +1. **Test Structure**: + + - Organize tests by language (e.g., `go`, `typescript`) and tool (e.g., `definition`, `diagnostics`) + - Each tool gets its own test file in a dedicated directory + - Use the common test framework from `languages/common` + +2. **Writing Tests**: + + - Use the `TestSuite` to manage LSP lifecycle and workspace + - Create test fixtures in the `workspaces` directory instead of writing files inline + - Use snapshot testing with `common.SnapshotTest` for verifying tool results + - Tests should be independent and cleanup resources properly + +3. **Running Tests**: + - Run all tests: `go test ./...` + - Run specific tool tests: `go test ./integrationtests/languages/go/definition` + - Update snapshots: `UPDATE_SNAPSHOTS=true go test ./integrationtests/...` + +Unit tests: + +- Simple unit tests should be written alongside the code in the standard Go fashion. + diff --git a/go.mod b/go.mod index e950a43..3a1275e 100644 --- a/go.mod +++ b/go.mod @@ -5,6 +5,7 @@ go 1.24.0 require ( github.com/fsnotify/fsnotify v1.8.0

Gitignore Integration: + - The watcher uses the go-gitignore package to parse and match gitignore patterns. + - The tests verify that files matching gitignore patterns are excluded from notifications. + - Additional tests in gitignore_test.go verify more complex patterns and matching scenarios. + +2. File Deletion in Excluded Directories: + - Since excluded directories are not watched, file deletion events in these directories are not detected. + +3. Large Binary Files: + - The tests don't verify the handling of large binary files due to test resource limitations. \ No newline at end of file diff --git a/internal/watcher/testing/gitignore_test.go

Add them to the workspaces directory - -3. **Running Tests**: - - Run all tests: `go test ./...` - - Run specific tool tests: `go test ./integrationtests/languages/go/definition` - - Update snapshots: `UPDATE_SNAPSHOTS=true go test ./integrationtests/...` - -Unit tests: - -- Simple unit tests should be written alongside the code in the standard Go fashion.
