eb41de1d35 Increase a timeout that's too short
This should have been longer to start with. This oversight is due
to a poor API in TestNetworkCallback that was made that way for
backwards compatibility ; b/157405399 tracks improving this API.

af7ca2d11f Increase ConnDiagsTest timeout for end-to-end test.
This change increases the delay allowed for administratorUid updates to
reach ConnectivityService in #testRegisterCallbackWithCarrierPrivileges.
Currently, there is no deterministic signal that can be used to wait for
this change, so Thread#sleep is required. This value is increased
because the previous delay did not give enough time for the
administratorUid change to reach CS, causing test flake.

4feab037a5 Skip flaky CTS tests for presubmit
Skip testRegisterCallbackWithCarrierPrivileges and
testContinuousQueriesInline for presubmit, as they are highly flaky.
These tests are still run in postsubmit as part of MTS. In order to put
the CTS suite in presubmit as early as possible, add the annotation so
they are skipped in TEST_MAPPING.

cce29fc44d Fix ConnDiags Test for invoke-after-validate and unregister CBs.
This change fixes several things in ConnectivityDiagnosticsManagerTest:
- testOnConnectivityReportAvailable creates the Test Network after
registering the ConnectivityDiagnosticsCallback. This ensures that the
callback is invoked only after the network is validated (not for the
on-register behavior).

- The TestNetworkInterface created while setting up the Test Network is
held onto for the duration of each test. This ensures that the interface
is not garbage collected during the test. While the interface is not
needed for the test, this change makes it clear when the interface is
cleaned up.

- All registered ConnectivityDiagnosticsCallbacks are unregistered at
the end of each test. This ensures that all accompanying NetworkRequests
are cleaned up. If NetworkRequests are leaked, unrelated test failures
can occur (the platform limits the number of NetworkRequests per UID).

a9dda29874 CTS test ConnectivityDiagnostics via CarrierPrivilegesTracker.
This change adds a CTS test for ConnectivityDiagnostics using
CarrierPrivilegesTracker to receive permissions for
ConnectivityDiagnostics callbacks.

Specifically, the test provides CarrierPrivileges to the test package
(android.net.cts) for the active subscription via Carrier Configs
overrides. CarrierPrivilegesTracker listens to the Carrier Configs
change and matches the loaded certificate with the test package, then
includes the test package UID as an administrator for the Network in
ConnectivityService. Then, a ConnectivityDiagnosticsCallback is
registered and receives a ConnectivityReport on register for the active
subscription.

This CL restricts ConnectivityDiagnosticsManagerTest to only being run
as @AppModeFull. This is required, as Instant Apps are not allowed
CHANGE_NETWORK_STATE (required for CM#requestNetwork) or
MANAGE_TEST_NETWORKS (required for TestNetworkManager#setupTestNetwork)
permissions - both of which are required for
ConnectivityDiagnosticsManagerTest.

ec38685a7f Toggle wifi when running CaptivePortalTest
Instead of reconnecting without disabling/re-enabling wifi in
CaptivePortalTest, actually do the toggle during the test and
on teardown to ensure that the BSSID blacklist is cleared.

CaptivePortalTest intentionally makes the network not validate, which
causes it to be added to the BSSID blacklist. Toggling wifi is necessary
to make sure the test does not affect other tests.

Also check development SDK instead of the exact SDK_INT number so that
the test can pass on current AOSP builds.

fd4a967604 Deflaky test for DnsResolverTest
It's possible that private DNS setting is not in the state we expected
when we tried to enable strict mode during tests. The problem here is
that there are 2 setting Uris(mode and specifier) relating to strict
mode, each of them might trigger private DNS setting changing evnet in
ConnectivityService.
Previously, we tried to enable strict mode with first set private DNS
mode and then private DNS specifier. This may result in 2 consecutive
private DNS changes events with very short intervals, which caused
conflicts between DnsResolver / NetworkMonitor and lead to flaky tests.

So
0. Use opportunistic as default mode if no default mode existed.
1. Change the order (mode and specifier) for enabling strict mode.
2. Change private DNS mode only when needed.
     (If original mode is "hostname", then we only need to set
     specifier)

402077cc3a Fix flaky test for DnsResolverTest
It's possible that private DNS setting is not in the state we expected
when we tried to enable strict mode during tests. The problem here is
that there are 2 setting Uris(mode and specifier) relating to strict
mode, each of them might trigger private DNS setting changing evnet in
ConnectivityService.
Previously, we tried to enable strict mode with first set private DNS
mode and then private DNS specifier. This may result in 2 consecutive
private DNS changes events with very short intervals, which caused
conflicts between DnsResolver / NetworkMonitor and lead to flaky tests.

So
1. Change the order (mode and specifier) for enabling strict mode.
2. Change private DNS mode only when needed.
     (If original mode is "hostname", then we only need to set
     specifier)

54978bda2d Use local defined NetworkSpecifier to verify test
Test will be affected by logic modification from different
NetworkSpecifiers. Since this test tries to test the behavior
of NetworkRequest but not NetworkSpecifier, use local defined
NetworkSpecifier to test to prevent repeating noisy breaks.
Also update test for testing invariant.
