Struct MockServoBackend 

pub struct MockServoBackend {
    pub call_log: Mutex<Vec<(String, String, String)>>,
    pub default_frame_id: String,
    pub known_targets: Mutex<Vec<String>>,
}

Mock backend — 用于单元测试 command dispatcher。

默认所有方法返回成功空响应。可通过字段调整特定响应。

@trace REQ-BAO-API-004 [level:library]

Fields

call_log: Mutex<Vec<(String, String, String)>>

default_frame_id: String

Page.navigate 默认返回的 frame_id。

known_targets: Mutex<Vec<String>>
