如何在Selenium Dynamic Grid中自定义录制视频文件名及输出目录名（替代默认video.mp4）

Got it, let’s walk through how to get the exact directory structure and filenames you want. Here’s a straightforward breakdown:

1. Replace Session-ID Directory with Custom Scenario Name #

By default, Dynamic Grid uses the session ID for the output folder. To override this, you’ll set the se:outputDirectory capability in your test’s desired capabilities. This defines a custom folder path relative to the base assets directory that Dynamic Grid uses.

Example Code Snippets #

Java:

ChromeOptions options = new ChromeOptions();
// Set custom directory name
options.setCapability("se:outputDirectory", "succesfullLoginScenario");
// Add other required capabilities (like browser version, etc.)
WebDriver driver = new RemoteWebDriver(new URL("http://your-grid-url:4444"), options);

Python:

from selenium import webdriver

chrome_options = webdriver.ChromeOptions()
chrome_options.set_capability("se:outputDirectory", "succesfullLoginScenario")
driver = webdriver.Remote(
    command_executor='http://your-grid-url:4444',
    options=chrome_options
)

This will create the assets/succesfullLoginScenario folder instead of the session-ID-named one.

2. Customize the Video Filename #

The default video.mp4 can be replaced using the se:videoName capability. Explicitly set your desired filename (including the .mp4 extension to avoid any auto-naming surprises).

Extending the Examples #

Java:

// Add this to the options setup
options.setCapability("se:videoName", "succesfullLoginScenario.mp4");

Python:

// Add this to the chrome_options setup
chrome_options.set_capability("se:videoName", "succesfullLoginScenario.mp4")

Final Result #

When you combine both capabilities, your test will generate exactly the structure you asked for:

-> assets/succesfullLoginScenario
-> sessionCapabilities.json
-> succesfullLoginScenario.mp4

Quick Tips #

• Ensure your Dynamic Grid nodes have video recording enabled (this is typically configured when starting the node with the video service).
• For parallel tests, generate unique directory/video names dynamically (e.g., pull the test method name from your framework like TestNG, JUnit, or pytest) to avoid overwriting files.
• Verify the Grid user has write permissions to the assets directory and custom subfolders.
