As a user, I can see Test Run statistics as a gadget

Users must be able to configure a dashboard widget which shows test run statistics for a list of tests. The gadget would ideally load the tests from either a saved filter or from a Test Set issue ID.

The following columns must be provided (one row per test):

• Issue (issue number of the Test issue, as a hyperlink)
• Summary (Summary of the Test issue, maybe also a hyperlink?)
• Linked Requirements
• Pass (number of test runs with a PASS result)
• Fail (number of test runs with a FAIL result)
• etc... columns for all test run result statuses configured in the system, including custom ones.
• Total Runs (total count of all test runs, which will be the sum of all the previous columns. Need to take into account whether non-final statuses are included)
• Success Rate (% of test runs contributing to the OK status of requirements, such as the PASS status)
• Last Run (most recent test run result. Need to take into account whether non-final statuses are included)

Example:

Filters:

• saved filter for Tests (for selecting Test issues)
• saved filter for Test Executions (for selecting Test Executions and related Test issues)
• test run's assignee, executedby

Chart Title: by default "Test Runs Statistics" but may be customized

Also, a pie chart must be provided by Xray grouping Test Runs by status.
