test: add mock tests for 8 executor handler files by retran · Pull Request #3 · retran/mxcli

retran · 2026-04-21T11:45:59Z

Summary

Add 49 tests across 8 new test files for executor handlers that previously had zero test coverage
Full mock coverage (happy-path, error-path, not-connected, edge cases) for: cmd_folders, cmd_move, cmd_rename, cmd_alter_page, cmd_features
Partial coverage (not-connected + error guards) for: cmd_styling, cmd_lint, cmd_import — happy paths depend on filesystem/DB connections not mockable through the Backend interface

Test Files

File	Tests	Coverage
`cmd_folders_mock_test.go`	9	Full (DropFolder + MoveFolder)
`cmd_move_mock_test.go`	6	Full (page moves, cross-module, errors)
`cmd_rename_mock_test.go`	11	Full (all 8 object types)
`cmd_alter_page_mock_test.go`	9	Full (properties, widgets, variables, layout)
`cmd_features_mock_test.go`	7	Full (ForVersion, AddedSince, connected)
`cmd_styling_mock_test.go`	5	Partial (not-connected guards)
`cmd_lint_mock_test.go`	1	Partial (not-connected guard)
`cmd_import_mock_test.go`	1	Partial (not-connected guard)

Add 49 tests across 8 new test files covering executor handlers that previously had zero test coverage: - cmd_folders: 9 tests (DropFolder + MoveFolder paths) - cmd_move: 6 tests (page moves, cross-module refs, error paths) - cmd_rename: 11 tests (entity/module/microflow/page/enum/assoc/const/nanoflow) - cmd_alter_page: 9 tests (set property, snippets, widgets, variables, layout) - cmd_features: 7 tests (ForVersion, AddedSince, connected, invalid version) - cmd_styling: 5 tests (not-connected guards for all 3 styling commands) - cmd_lint: 1 test (not-connected guard) - cmd_import: 1 test (not-connected guard) Styling, lint, and import have partial coverage (not-connected + error paths only) because their happy paths depend on filesystem or external DB connections that cannot be mocked through the current Backend interface.

Pull request overview

Adds mock-based unit tests for several mdl/executor command handlers that previously lacked coverage, focusing on connection guards plus selected happy/error paths using MockBackend and shared test helpers.

Changes:

Introduces new mock test suites for cmd_folders, cmd_move, cmd_rename, cmd_alter_page, and cmd_features with broader behavior coverage.
Adds minimal “not connected” guard tests for handlers with dependencies not easily mockable via the current Backend interface (cmd_styling, cmd_lint, cmd_import).

+		MovePageFunc:    func(p *pages.Page) error { movedPage = p; return nil },
+	}
+	h := mkHierarchy(mod)
+	withContainer(h, pg.ID, mod.ID)


withContainer is intended to be called with an element's ContainerID (see helper doc), but this passes the page's own ID. This makes the hierarchy setup misleading and won't exercise module resolution behavior if the page is ever placed under a non-module container (e.g., a folder). Use pg.ContainerID (and set it to a folder ID when relevant) when registering parentage.

Suggested change

withContainer(h, pg.ID, mod.ID)

withContainer(h, pg.ContainerID, mod.ID)

+		},
+	}
+	h := mkHierarchy(srcMod, dstMod)
+	withContainer(h, pg.ID, srcMod.ID)


Same issue here: withContainer(h, pg.ID, srcMod.ID) passes the unit ID instead of pg.ContainerID, so the hierarchy wiring doesn't reflect production behavior (FindModuleID is called with ContainerID). Prefer wiring pg.ContainerID (or a folder ID) to the owning module.

Suggested change

withContainer(h, pg.ID, srcMod.ID)

withContainer(h, pg.ContainerID, srcMod.ID)

+		MovePageFunc:    func(p *pages.Page) error { return fmt.Errorf("disk full") },
+	}
+	h := mkHierarchy(mod)
+	withContainer(h, pg.ID, mod.ID)


Same issue here: withContainer(h, pg.ID, mod.ID) uses the page ID rather than pg.ContainerID, so the hierarchy setup is inconsistent with how the executor resolves modules (FindModuleID(p.ContainerID)).

Suggested change

withContainer(h, pg.ID, mod.ID)

withContainer(h, pg.ContainerID, mod.ID)

PR description says this file has "Full (all 8 object types)" coverage for RENAME, but the tests here only cover ENTITY, MICROFLOW, MODULE, ASSOCIATION, plus a PAGE not-found case. If full coverage is intended, add tests for NANOFLOW / ENUMERATION / CONSTANT and a PAGE happy path (and update the PR description/table if full coverage is not actually in scope).

TestAlterStyling_NotConnectedForWrite is permanently skipped, so it doesn't add coverage and can cause CI noise if skipped tests are tracked. Consider removing it, or (if you want to test the write-guard) introduce a test seam (e.g., make ConnectedForWrite depend on a backend capability flag that the mock can control).

Suggested change

func TestAlterStyling_NotConnectedForWrite(t *testing.T) {

mb := &mock.MockBackend{

// Connected but read-only: IsConnected returns true but we need

// ConnectedForWrite to fail. ConnectedForWrite delegates to Connected()

// which calls IsConnected(), so we can't differentiate with the mock.

// Skip this test — ConnectedForWrite() == Connected() in current impl.
