我正在尝试通过Appium和webdriverio实现IOS模拟器的自动化。 Appium正在创建具有随机模拟器名称的模拟器，例如“ appiumTest-4F75F52A-4C52-48F0-B818-60C891F72E95-iPhone XR”。 它根据已编写的测试数量来创建模拟器数量。我试图弄清楚为什么appium正在创建模拟器的实例。
测试所需的功能：
功能：[{ maxInstances：1 deviceName：“ iPhone XR”， platformName：“ iOS”， 应用：“应用/路径”， platformVersion：'12 .2'， 方向：“肖像”， noReset：是的， automationName：'XCUITest'， useNewWDA：是的， waitForQuiescence：否， newCommandTimeout：240， }]
给出的是Ios模拟器测试的 APPIUM 日志
