Test Methodology
----------------

We will test the functionality and performance of the new rendering pipeline.

Testing the new pipeline does not require new test development, since no Java 2D APIs will change. Existing tests and real-world applications will suffice.

Test Inventory
--------------

**Functionality Testing :**

We will use below tests to test functionality of the new rendering pipeline:

    

 - JDK jtreg regression tests - AWT, Swing and Java2D - automated and
   manual tests
 - JCK Tests - AWT, Swing and Java2D - automated and manual tests
 - Java 2D Demo - manual test
 - Font 2D Demo - manual test
 - SwingSet2 Demo - manual test
 - JavaFX-Swing inter-op sanity tests - manual test
    - Test JFXPanel (JFXPanel is a component to embed JavaFX content into
    Swing applications)
    - Test SwingNode (This Node is used to embed a Swing content into a JavaFX application)   
 - Examples of large-scale real world applications - manual test
    - Intellij IDEA IDE usage
    - Netbeans IDE usage

**Performance Testing :**

We will use below tests to test performance of the new rendering pipeline:

    

 - J2DBench, a Java 2D bench-marking application included in JDK
 - RenderPerfTest - see "New Tests" below
 - IDE rendering performance tests -
    - IntelliJ IDEA rendering performance
    - Netbeans IDE rendering performance
        - A set of identified Netbeans IDE UI responsiveness tests 


**New Tests:**

- RenderPerfTest - A custom stress test that renders multiple objects of the same primitive type and measures frames per second (FPS)

Test Configurations

Success Criteria
----------------
No critical functional and performance regressions as compared to OpenGL rendering pipeline.
