Start by running the fullstack-helm-client tests and reading HelmClientTest, especially ChartInstallOptionsTestParameters and the timed-out cases shown in the report. Trace how those parameterized tests perform chart installation and identify what can be refactored to avoid the 10-second timeouts; done means the affected tests complete reliably without timeouts and the suite runs faster.
