From 877404aab98968623a996635cd8a5ed6f48de1a6 Mon Sep 17 00:00:00 2001 From: Shawn <5414767+playcations@users.noreply.github.com> Date: Fri, 1 Aug 2025 13:56:43 -0400 Subject: [PATCH] Bug fixes and test cases added - Added more tests for checkpoints - Fixed bug where fco was not updating after checkpoints properly. - It would include all previous edits from the previous checkpoint on tasks that were mid edit. - Added timestamp checking to cover the edge case. - Added tests for the edge cases covered. - Bug fix for users enabling FCO after some time using the task. - One more edge case being covered when the user enables fco after talking with the task for a while. - To solve this, added test cases and have the settings enabled to set the timestamp if it was previously disabled. - Added better separation of concerns for testing of FCO web ui. --- src/core/checkpoints/__tests__/index.spec.ts | 209 +++++ src/core/webview/ClineProvider.ts | 2 +- src/core/webview/webviewMessageHandler.ts | 5 - .../checkpoints/ShadowCheckpointService.ts | 21 + .../__tests__/ShadowCheckpointService.spec.ts | 515 +++++++++++ .../file-changes/FCOMessageHandler.ts | 95 ++ .../__tests__/FCOMessageHandler.test.ts | 847 ++++++++++++++++++ .../file-changes/FilesChangedOverview.tsx | 19 + .../__tests__/FilesChangedOverview.spec.tsx | 479 ++++++++++ 9 files changed, 2186 insertions(+), 6 deletions(-) create mode 100644 src/core/checkpoints/__tests__/index.spec.ts create mode 100644 src/services/file-changes/__tests__/FCOMessageHandler.test.ts diff --git a/src/core/checkpoints/__tests__/index.spec.ts b/src/core/checkpoints/__tests__/index.spec.ts new file mode 100644 index 0000000000..20605ba3fa --- /dev/null +++ b/src/core/checkpoints/__tests__/index.spec.ts @@ -0,0 +1,209 @@ +// Use doMock to apply the mock dynamically +vitest.doMock("../../utils/path", () => ({ + getWorkspacePath: vitest.fn(() => { + console.log("getWorkspacePath mock called, returning:", "/mock/workspace") + return "/mock/workspace" + }), +})) + +// Mock the RepoPerTaskCheckpointService +vitest.mock("../../../services/checkpoints", () => ({ + RepoPerTaskCheckpointService: { + create: vitest.fn(), + }, +})) + +import { describe, it, expect, beforeEach, afterEach, vitest } from "vitest" +import * as path from "path" +import * as fs from "fs/promises" +import * as os from "os" +import { EventEmitter } from "events" + +// Import these modules after mocks are set up +let getCheckpointService: any +let RepoPerTaskCheckpointService: any + +// Set up the imports after mocks +beforeAll(async () => { + const checkpointsModule = await import("../index") + const checkpointServiceModule = await import("../../../services/checkpoints") + getCheckpointService = checkpointsModule.getCheckpointService + RepoPerTaskCheckpointService = checkpointServiceModule.RepoPerTaskCheckpointService +}) + +// Mock the FileChangeManager to avoid complex dependencies +const mockFileChangeManager = { + _baseline: "HEAD" as string, + getChanges: vitest.fn(), + updateBaseline: vitest.fn(), + setFiles: vitest.fn(), + getLLMOnlyChanges: vitest.fn(), +} + +// Create a temporary directory for mock global storage +let mockGlobalStorageDir: string + +// Mock the provider +const mockProvider = { + getFileChangeManager: vitest.fn(() => mockFileChangeManager), + log: vitest.fn(), + get context() { + return { + globalStorageUri: { + fsPath: mockGlobalStorageDir, + }, + } + }, +} + +// Mock the Task object with proper typing +const createMockTask = (options: { taskId: string; hasExistingCheckpoints: boolean; enableCheckpoints?: boolean }) => { + const mockTask = { + taskId: options.taskId, + instanceId: "test-instance", + rootTask: undefined as any, + parentTask: undefined as any, + taskNumber: 1, + workspacePath: "/mock/workspace", + enableCheckpoints: options.enableCheckpoints ?? true, + checkpointService: null as any, + checkpointServiceInitializing: false, + clineMessages: options.hasExistingCheckpoints + ?
