             Summary: Improve tests for Elasticsearch 8 connector
                 Key: FLINK-35472
                 URL: https://issues.apache.org/jira/browse/FLINK-35472
             Project: Flink
          Issue Type: Improvement
          Components: Connectors / ElasticSearch, Tests
            Reporter: Mingliang Liu


Per discussion in [this PR|https://github.com/apache/flink-connector-elasticsearch/pull/104],  it makes the tests more reusable if we use parameterized tests. It requires some changes of the existing tests, which includes:
# Make base test class parameterized with secure parameter. As JUnit 5 has limited support for parameterized tests with inheritance, we can use the {{ParameterizedTestExtension}} introduced in Flink, see this doc
# Manage the test container lifecycle instead of using the managed annotation {{@Testcontainers}} and {{@Container}} so that the test containers can be used as a singleton for all tests in the suite
# Create and use common methods in the base class that concrete test classes can be mostly parameter-agnostic

This JIRA intends to not change any logic or functionality. Instead it focuses on tests refactoring for more reusable tests and future proof.
