7.0 CTS fail 项分析(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.

问题分析：这两项测试与耳机相关，模拟插入耳机状态下短按、长按按钮的行为，Google CTS 要求短按静音，长按挂断电话。

2、    CtsSecurityHostTestCases
android.security.cts.SELinuxHostTest#testAospServiceContexts    fail
junit.framework.ComparisonFailure: Lines do not match: expected: but was:

问题分析：在该测试例中测试机root目录下的service_contexts 对应源码中的/system/sepolicy/service_contexts的71行，应该是:
71 media.log u:object_r:audioserver_service:s0
可以和CTS jar中的general_service_contexts 完全匹配，如果不是，那就会报错。

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

问题分析：该测试项需要架设IPV6网络才可以进行

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：手机在测试时，将10111加入黑名单，但是后续测试的时候，发现有从黑名单里移除，所以不符合预期出错。Log如下：
//将10111这个APP加入黑名单
