java - 有些Ashot策略有 "simulator"字样，它们有什么区别？

Question

我一直致力于 Selenium 的 Ashot 库和 Browserstack API 来截取设备的屏幕截图。通过查看射击策略，我注意到某些可用策略有一个“模拟器”策略。

ashot 库的文档很少:/

public static ShootingStrategy iPad2WithIOS8() {
    VariableCutStrategy cutStrategy = new VariableCutStrategy(41, 65, 960);
    return viewportNonRetina(500, cutStrategy);
}

public static ShootingStrategy iPad2WithIOS8Simulator() {
    VariableCutStrategy cutStrategy = new VariableCutStrategy(41, 65, 1250);
    return viewportNonRetina(500, cutStrategy);
}

public static ShootingStrategy iPad2WithIOS8Retina() {
    VariableCutStrategy cutStrategy = new VariableCutStrategy(41, 65, 960);
    return viewportRetina(500, cutStrategy, 2.0F);
}

public static ShootingStrategy iPad2WithIOS8RetinaSimulator() {
    VariableCutStrategy cutStrategy = new VariableCutStrategy(41, 65, 1250);
    return viewportRetina(500, cutStrategy, 2.0F);

其中每一个都有一个模拟器版本。有人知道它们有什么区别吗？

Answer 1

也许是因为其中一个适用于模拟，其他适用于真实设备。
