This module contains tests that verify Ignite cluster upgrades.
The PersistenceTestBase serves as a base compatibility test. It starts and inits a cluster of a specified previous version, calls setupBaseVersion method with the Ignite client connected to the first node of the cluster. Then it stops the cluster and starts it in the embedded mode using current sources. This is done once per class, similar to the ClusterPerClassIntegrationTest. This base test is parameterized using the list of versions from the versions.json resource file. By default the test takes two latest versions as the base version. If the testAllVersions system property is defined, then all the versions are tested.
When new version is released, add new object to the versions array in the versions.json file like so:
{ "version": "3.1.0" }
In case there's a need for the specific node configuration override for that version, the configOverrides object can be added:
{ "version": "3.0.0", "configOverrides": { "ignite.network.membership.scaleCube.metadataTimeout": 10000 } }
Before executing test task, resolveCompatibilityTestDependencies task should be started to download all necessary dependencies from the Maven repository.
