Groups of test cases

Often we want to get test results not only for individual test case, but for wider scope, for example all code in a function or module (source file). This information can be obtained by creating groups of test cases.

The code, which belongs to group is defined in a filter section. For example, by specifying a module in filter section, all code from that module is part of the group. testIDEA then shows all unit test cases, which test code (functions) from the selected group as members of the group. Test cases can be added to groups only changing filter settings.

Groups are used only as different view of existing test cases and to perform statistics on results. They do not alter relations between base and derived tests. All test cases still exist on their own in testIDEA - they are shown as test cases without groups. All test cases in a project are always shown below the groups in Outline view, as shown in the image below.

Groups are dynamic containers - when group is created, or testIDEA file is opened, groups contain no test cases. testIDEA shows which test cases belong to group only after symbol refresh.

Important: If we use Delete action on test case shown in a group, the test case will be deleted from a project, not only removed from the group.

Group hierarchy

Groups can have sub-groups as children. Test cases are first filtered by parent group, and only those, which pass this filter, are used as an input to the sub-group.
It is common use case to define parent top level group with filter for module (source file), and sub-groups with filter for modules (source files), and sub-sub groups filter test cases on function being tested.

If parent and sub-groups exist, and a test case belongs to both of them, then it is shown only in the sub-group. Statistics for parent group is calculated from all test cases in the group and sub-groups, because they all belong to the parent group.

Creating groups

Before we create groups it is recommended to refresh symbols in testIDEA (see command iTools | Refresh). Test cases can be properly assigned to groups only with up-to-date symbols. testIDEA automatically assigns test cases to groups when symbols are refreshed.

Menu commands

There exist two commands in menu Test and in context menu of the Outline view:

Filter in the created group is empty, which means that all test cases belong to this group. See section Filter configuration below for details.


Wizard can be used to create hierarchies of groups for several download files, modules, and functions at once. It is accessible with command iTools | Create Groups ...

If the wizard is empty, click refresh button in the top right corner. When group hierarchy is displayed, select groups which you want to be created. Click OK to create groups.
Filters are already configured in created groups.

Running test cases in groups

During test case development and group configuration it is possible to run only sub-set of all test cases, for example only test cases in a group.
Note: Symbols are not automatically refreshed in such case and test cases are not reassigned to groups, because in larger projects with many symbols refresh may take few seconds and refreshing would be annoying when running one or few test cases. When command Run All is executed, then symbols are refreshed and test cases reassigned to groups before the run.

Group results

Group results consist of three sections:
