Interpretation of insights

You can find information about interpreting the Machine learning (ML) insights into the supported parameters that are analyzed by HCL DevOps Test Hub (Test Hub) after certain tests are run.

Parameters analyzed through ML

The following parameters in Performance tests or Schedules are supported for analysis by using ML capabilities in Test Hub:
  • The Response Time Lock-Step Pattern parameter.
  • The Response Time Standard Deviation Pattern parameter.
  • The Throughput Drop Pattern parameter.

Test Hub analyzes the parameters based on certain criteria as detailed in Criteria for analysis of the parameters and then presents its findings as insights about the parameters.

Details of the insights

The insights about the parameters analyzed are displayed in the Insights section on the project Overview page or on the Insights page in a project.

The insights analyzed for the parameters from various tests that were run in the project are listed in a table. The table lists the following information:
  • Name of the test asset in the Test column.
  • The parameter analyzed in the Insight column.
  • The level of confidence with which the analysis of the parameter was done in the Confidence column. The level of confidence displayed for the analysis can be as Lowest, Low, Medium, High, or Highest. You can view the confidence level as a number when you hover the cursor over the text in the Confidence column.
  • The timestamp of the completed analysis in the Identified on column.
  • The labels that you added for the specific test run in the Labels column.
  • The components in the System Model that are associated with the test asset in the Components column.
