【问题分析】

通过查看gts测试源码，测试方法是testRunSilentWifiTetherProvisioningAndEnable ()
为何报错是在不相关的兄弟方法

ensureWifiApOff(ProvisioningTest.java:132)
setUp(ProvisioningTest.java:108)

按照报错去查看原因，找到报错是因为没有请求到期望的state---WIFI_AP_STATE_DISABLED = 11;

源码追溯：
com.google.android.tethering.gts.ProvisioningTest.java

private static final int WIFI_AP_TIMEOUT = 15000;

2.run gts -m GtsTetheringTestCases -t com.google.android.tethering.gts.ProvisioningTest#testRunUiBluetoothTetherProvisioningAndEnable 

【问题概述】

【问题分析】

通过查看gts测试源码得知，进行该项测试，需要判断(是否支持共享)---->>isTetheringSupported()；
该方法通过读属性"ro.tether.denied"获取结果，

问题点1：

我们的盒子中没有"ro.tether.denied"属性，只有

console:/ # getprop | grep tether
[net.tethering.noprovisioning]: [true]  

问题点2：

shouldRunTest() 方法判断读到的属性，应该是ro.tether.denied = 否，才能开启测试，
但是我们的属性[net.tethering.noprovisioning]: [true]

问题点3：

考虑：
我们要改一下属性[net.tethering.noprovisioning]属性的值？
还是添加新的属性[ro.tether.denied]
