Summary: .NET: Fix flaky IgniteStartStopTest.TestStartDefault
Key: IGNITE-29274
URL: https://issues.apache.org/jira/browse/IGNITE-29274
Project: Ignite
Issue Type: Task
Reporter: Maksim Davydov
Assignee: Maksim Davydov
IgniteStartStopTest.TestStartDefault starts a node with the default
configuration, so discovery
uses TcpDiscoveryMulticastIpFinder (group 228.1.2.4, port 47400). On TeamCity
agents that share a network, the node can find a node of another build running
at the same time:
- if both nodes have the same feature set, the test node joins the other
cluster and the test
fails with "Unexpected number of nodes in the cluster";
- if the feature sets differ at the same version, the join fails with an
AssertionError in
IgniteMessageSerializationContext.resolveComponentSerializationContext.
Example of the second case: Platform .NET (Core Linux) build #53280 on agent
lin-13,
https://ci2.ignite.apache.org/buildConfiguration/IgniteTests24Java8_PlatformNetCoreLinux/9485923
Fix: use TestUtils.GetStaticDiscovery() (127.0.0.1:47500), as the other tests
do. The rest of
the configuration stays default, which is what the test checks.
