Hide unit tests from Call Hierarchy

1. In the Call Hierarchy view, click the white downwards arrow icon.
2. Select “Filters…”.
3. Check “Filter Test Code”.
4. Click the refresh button (or press F5).

The test classes and methods should not be visible anymore.

The “Filter Test Code” checkbox was added in Eclipse Photon. In earlier versions, you can select the “Name filter patterns” checkbox and filter tests based on your naming convention (e.g. if the classes end with “Test” then enter *Test).
