With Winter 16 (API 35), the Force.com IDE began providing "run configurations for Apex tests, with configurable logging levels". See the Force.com IDE Release Notes for details on this feature and how to configure them. Once you have them configured, you press a green arrow in the menu panel above to run your selected test class (outlined in red). See graphic below.
