Duplicated Test Cases in Test Sets
When adding a test case to a test set you can add the same test case multiple times resulting in duplicate test cases in the test set. Alternatively, a test set can contain duplicate test cases if the Allow Duplicates Boolean field of the test set is set to True.
When running a test set with duplicate test cases, the Test Runs page displays and runs the same test case as many times as it appears in the test set, and in the same order as the duplicates appear in the test set.
When building the test set, duplicate test cases are indicated with 
icon. To remove the duplicates of an individual test case, click next to the test case. To remove all duplicate test cases, click Remove All Duplicates in the warning message.

• Set the Allow Duplicates field to True or False in your test set.
 | The Allow Duplicates field is a hidden field in Tracker Configuration. To make it visible, select the Show hidden fields option under the Fields tab in the > . |
For legacy trackers, add this field if necessary:
• Set its default value globally by editing the general.xml file as follows:
<testManagement testSetAllowDuplicates="true" ></testManagement>
For more information, see Application Configuration This global default value is applied to the current test set, only if the test set has – value in Allow Duplicates hidden field.
