Events

[robocoder]

CompatBuster:

• $this->curl no longer prefixes the command with a leading slash, e.g., '/status'

Features:

• Dispatches before/after/error events for each WebDriver command

Sample Before Event:

{
    "event": "before",
    "command": "webdriver_command",
    "parameters": []
}

Sample After Event:

    "event": "after",
    "command": "webdriver_command",
    "result": { ... }

Sample Error Event:

{
    "event": "error",
    "command": "webdriver_command",
    "error", "WebDriverExceptionClassName"
}
