Saucelabs测试无法在模拟器上运行：在会话请求中未指定browserName或设备

问题描述

我尝试在Android模拟器上使用webdriverio和saucelabs进行测试，但我遇到了这个问题：

Find below the capabilities:

“ browserName”：“”， “ deviceName”：“ Android Emulator”， “ automationName”：“ UiAutomator2”， “ deviceOrientation”：“肖像”， “ platformName”：“ Android”， “ app”：“ sauce-storage：app-XXXXXX.apk”， “ waitforTimeout”：10000， “ commandTimeout”：10000， “名称”：“ XXXX”， “ build”：“ XXXXXX android测试”， “ locale”：“ fr”， “ language”：“ fr”， “ sauce：options”：{ }

解决方法

您在功能中指定了一个sauce：options参数，Sauce使用该参数来确定您想要一个符合w3c的会话，但是它为空，因此无法识别特定的值。

将app参数放置在sauce：options参数内，它应该与w3c语法一起使用，或者删除sauce：options，它将使用旧式语法来工作。
