Data Format

Each app folder contains a checkpoint_<app_name>.json with the following structure:

{
  "app": "douyin",                                      # ← App name
  "testcases": [                                        # ← List of tasks
    {
      "testcase_id": 1,                                 # ← Task ID (unique within app)
      "testcase_desc": "...",                           # ← Natural language task description
      "clean": {                                        # ← Clean (unperturbed) trace
        "trace": [
          {
            "checkpoint_id": 1,                         # ← Step index
            "screenshot_path": "./douyin_tc1_b_1.png",  # ← Relative path to screenshot
            "xml_path": "./douyin_tc1_b_1.xml",         # ← Relative path to XML
------------------------------------------------------------ Ground truth annotations ------------
            "action": "click",               # ← action
            "bbox": [340, 64, 432, 152],     # ← Target bounding box [x1,y1,x2,y2]
            "input_value": "..."             # ← (Optional) For input/scroll actions
--------------------------------------------------------------------------------------------------
          }
        ]
      },
      "noise": [                                       # ← List of perturbed traces
        {
          "type": "VE",                                # ← Perturbation type
          "trace": [...]                               # ← Same structure as clean trace
        }

Usage Example

import json
from pathlib import Path

data_dir = Path("data/douyin")
with open(data_dir / "checkpoint_douyin.json") as f:
    gt = json.load(f)

for tc in gt["testcases"]:
    print(f"Task {tc['testcase_id']}: {tc['testcase_desc']}")

    # Clean trace
    print("  Clean trace:")
    for step in tc["clean"]["trace"]:
        img_path = data_dir / step["screenshot_path"].lstrip("./")
        xml_path = data_dir / step["xml_path"].lstrip("./")
        print(
            f"    Step {step['checkpoint_id']}: {step['action']} "
            + (f"bbox={step['bbox']}" if step.get('bbox') else "")
            + (f" input_value={step['input_value']}" if step.get('input_value') else "")
        )

    # Noise traces
    for noise in tc["noise"]:
        print(f"  Perturbation: {noise['type']}")
        for step in noise["trace"]:
            img_path = data_dir / step["screenshot_path"].lstrip("./")
            xml_path = data_dir / step["xml_path"].lstrip("./")
            print(
                f"    Step {step['checkpoint_id']}: {step['action']} "
                + (f"bbox={step['bbox']}" if step.get('bbox') else "")
                + (f" input_value={step['input_value']}" if step.get('input_value') else "")
            )
