playwright-screen-recording
GitHub基于Playwright录制浏览器测试视频,用于PR审查和Bug修复验证。支持无头模式生成.webm文件,通过添加暂停、结合终端日志断言及使用真实数据,提供直观的视觉证据以辅助代码评审和问题排查。
Trigger Scenarios
需要录制浏览器操作视频以进行PR审查
需要录制前后对比视频以验证Bug修复
需要为回归测试提供视觉证据

Playwright Screen Recording for Test Verification
Use Playwright's video recording to capture headless browser operations as .webm videos for PR review or bug fix verification.
Core Usage
from playwright.sync_api import sync_playwright
import tempfile
from pathlib import Path
video_dir = Path(tempfile.mkdtemp())
with sync_playwright() as pw:
browser = pw.chromium.launch(headless=True)
context = browser.new_context(
viewport={"width": 1400, "height": 900},
record_video_dir=str(video_dir),
record_video_size={"width": 1400, "height": 900},
)
page = context.new_page()
page.goto(f"file:///path/to/test.html")
# ... perform test actions, add pauses for readability ...
page.wait_for_timeout(800) # pause so viewers can see the current state
page.close()
context.close() # video is finalized after context.close()
browser.close()
# Retrieve the recorded video
videos = list(video_dir.glob("*.webm"))
if videos:
videos[0].rename("demo.webm")
Use Cases
- Bug fix verification: record before/after comparisons showing button state changes, UI behavior differences
- PR Review: attach .webm video so reviewers can visually understand the change
- Regression test evidence: record critical interaction paths as visual proof of passing tests
Recording Tips
Add pauses between actions
page.click(".some-button")
page.wait_for_timeout(800) # let viewers see the click effect
page.keyboard.press("ArrowRight")
page.wait_for_timeout(600) # let viewers see the navigation result
Combine assertions with terminal logging
state = get_nav_state(page)
print(f"[1] Title: {state['title']}")
print(f" prev disabled: {state['prevDisabled']} (expected: True)")
assert state["prevDisabled"] is True
print(" PASS")
Terminal output paired with the recorded video provides dual verification.
Prefer real data
Use existing real trace data from the project rather than synthetic data for more convincing demos:
# Build test HTML from a real trace file
records = []
with open(".traces/trace_xxx.jsonl") as f:
for line in f:
# Escape </script> to prevent breaking the HTML script block
records.append(line.strip().replace("</script>", '</scr" + "ipt>'))
Notes
- Video format is
.webm(VP8 codec), supported by most players and browsers - Each
pageproduces a separate video file record_video_sizecontrols video resolution — keep it consistent withviewport- Recording works in headless mode, no display required
- Video files are typically a few hundred KB, suitable for attaching to PRs or chat
