7.0 CTS fail 項分析(二)

1、    CtsTelecomTestCases
android.telecom.cts.WiredHeadsetTest#testInCallLongPress_hangupCall    fail
junit.framework.AssertionFailedError: Call: Call [id: TC@1, state: HOLDING, details: [pa: PhoneAccountHandle{CtsConnectionService, xtstest_CALL_PROVIDER_ID, UserHandle{0}}, hdl: tel:10000, caps: [Capabilities:], props: [Properties:]]] should be in state 7 expected:<7> but was:<3>

android.telecom.cts.WiredHeadsetTest#testInCallShortPress_togglesMute      fail
junit.framework.AssertionFailedError: No call added to InCallService.

問題分析：這兩項測試與耳機相關，類比插入耳機狀態下短按、長按按鈕的行為，Google CTS 要求短按靜音，長按掛斷電話。

2、    CtsSecurityHostTestCases
android.security.cts.SELinuxHostTest#testAospServiceContexts    fail
junit.framework.ComparisonFailure: Lines do not match: expected:<media.[log u:object_r:audio]server_service:s0> but was:<media.[imageeffect u:object_r:camera]server_service:s0>

問題分析：在該測試例中測試機root目錄下的service_contexts 對應源碼中的/system/sepolicy/service_contexts的71行，應該是:
71 media.log u:object_r:audioserver_service:s0
可以和CTS jar中的general_service_contexts 完全符合，如果不是，那就會報錯。

3、CtsNetTestCases
android.net.cts.DnsTest#testDnsWorks    fail
junit.framework.AssertionFailedError: [RERUN] DNS could not resolve ipv6.google.com, check the network supports IPv6

問題分析：該測試項需要架設IPV6網路才可以進行

3、    CtsHostsideNetworkTests
com.android.cts.net.HostsideRestrictBackgroundNetworkTests#testDataSaverMode_blacklisted    fail
java.lang.AssertionError: on-device tests failed:
junit.framework.ComparisonFailure: wrong status expected:<[EN]ABLED> but was:<[DIS]ABLED>

原因分析：手機在測試時，將10111加入黑名單，但是後續測試的時候，發現有從黑名單裡移除，所以不符合預期出錯。Log如下：
//將10111這個APP加入黑名單
