Test Manager Guide
This guide describes how to keep track of the performance of the application by evaluating the test results. This guide is intended for test managers.
Evaluating results in web analytic reports
After the test run, evaluate the results in the web analytic reports. Web analytics collect data using new technologies thereby providing better user experience.
Customizing reports
You can customize reports to specifically investigate a performance problem in more detail than what is provided in the default reports.
Viewing trending reports
To view the trend of response time for an application over a period of time, open the trend report for a run. In addition to the response time, you can view the trend for the loops, transactions, and performance requirements for the application.

  - Evaluating results in web analytic reports
    After the test run, evaluate the results in the web analytic reports. Web analytics collect data using new technologies thereby providing better user experience.
    - Comparing results among runs
      To analyze the difference between two or more reports, you can compare them. For example, to analyze the performance of the application at different time slots or different milestone builds, you can compare two runs.
    - Comparing schedule stages
      When you are running a schedule, in this context, is used to refer to VU Schedule and Rate Schedule that contains stages, time ranges are automatically created for each stage. You can view a report that compares these stages, and you also can set preferences to display the report automatically at the end of a staged run.
    - Comparing results from various regions or agent locations
      When you run a schedule that includes agents from different regions, use the Web Analytic reports to compare the performance data from these regions.
    - Generating functional reports
      You can generate functional reports of your tests, which summarize the pass or fail verdicts of elements in the test log. Functional reports are generated from the test run as HTML files that use predefined report designs.
    - Publishing functional reports to the server
      If you have generated functional reports for your test results, you can associate functional reports to test results and then publish them to IBM® Rational® Test Automation Server so that others can view them from the web browser.
    - Publishing test results to the server
      The test results indicate the quality of the application under test. Different stakeholders might want to check the quality of the application but do not have the desktop client installed. As a desktop client user, you can publish test results to IBM® Rational® Test Automation Server so that others can view them from the web browser.
    - Publishing specific results to the server
      If you have a single test result or multiple test results that are not published to IBM® Rational® Test Automation Server, you can publish a single or all of them simultaneously.
    - Customizing reports
      You can customize reports to specifically investigate a performance problem in more detail than what is provided in the default reports.
      - Creating custom reports
        If the default reports do not address your needs, you can create your own reports.
      - Viewing trending reports
        To view the trend of response time for an application over a period of time, open the trend report for a run. In addition to the response time, you can view the trend for the loops, transactions, and performance requirements for the application.
      - Filtering data in test results
        You can filter the data in a test result that is displayed in a report so that you can remove the unnecessary data and focus on the data that is significant for the analysis.
      - Adding additional counters on a separate page
        You can add additional counters on a separate page without editing an existing report to investigate performance problems in detail.
      - Customizing the appearance of graphs in a report
        To display the data in a table, bar chart, or line chart in a manner that caters to your test requirements, use the controls that are available in the View Options of a report.
      - Changing the report displayed during a run
        Use this page to select the default report that opens during a run. Typically, you select Determine default report based on protocols in test, which determines the protocols that you are testing and automatically opens the appropriate protocol-specific reports.
      - Modifying counters in a graph
        To gather additional information for diagnosing performance problems, you can modify the counters that are displayed in a graph.
      - Correcting time offset
        Response time breakdown and resource monitoring data is time stamped using the system clock of the host computer. If there are differences between the system clocks of the host computers that you include in a test, then response time breakdown and resource monitoring data are skewed in reports. The best practice is to synchronize the system clocks on all computers that you include in a test. When this is not possible, you can correct the time offset of each host computer after a test run. Typically, correct the time offset on all computers to match the system clock of the workbench computer.
    - Export test results
      You can export the test result in different formats to share it with different stakeholders.
    - Viewing response time breakdown
      You can do detailed analysis of the response time to find bottlenecks in the HTTP traffic of the application.
  - Logs overview
    Rational® Performance Tester uses logs to store different types of information, which you can use to determine the reason for a test failure.
  - Reports and counters
    After the tests or schedules are run and completed, you can view the results and open the reports to analyze the verdict, the performance, and statistics.
- Troubleshooting Guide
  This guide describes how to analyze and resolve some of the common problems that you might encounter while you work with Rational® Performance Tester.
- Reference Guide
  This guide describes, additional topics to gain more knowledge about Rational® Performance Tester.
- All Guides (PDFs)

Viewing trending reports

To view the trend of response time for an application over a period of time, open the trend report for a run. In addition to the response time, you can view the trend for the loops, transactions, and performance requirements for the application.

About this task

The trend report can help you determine the response times of the application at different milestones. For instance, you can run the performance test for sprint or milestone builds and tag them. When generating the trend report, you can specify conditions such as results that are less than 60 days old and include 'milestone' tag. Execution Results Filters

Execution Results Filters

You cannot save a trend report. So, if you close the report, you have to generate it again.

Procedure

To view the trend report:

In the Test Navigator view, select the run for which to open the trend report.
Right-click the run and click View Trend Report.
To view the trend that is based on certain criteria, in Filter, select a filter criteria.
If there is no customized filtering criteria, create one by clicking Manage and then Add.
To save the criteria, click Save, specify a name to the filter, and click OK.
The results in the execution results table are filtered out according to the specified criteria.
Click OK.
The trend report is generated.
