Where I can find OpenJDK tests?

Question

I am interested in how JDK is tested itself, what test engine it uses.

I found some links:

• https://github.com/ddopson/openjdk-test - does not look as official repository
• http://openjdk.java.net/jtreg/ - contains regression tests, points to Jonathan Gibbons' blog but seems that it is unavailable

Also, I would like to see how frameworks like Swing and JavaFX are tested.

Are there any manuals / instructions available about how to execute / look through JDK tests?

Answer 1

OpenJDK comes with its own regression test suite.

The tests can be found in the 'test' subdirectory of the individual repositories making up a JDK forest. For example, javax.swing jtreg tests for JDK 9 can be found at http://hg.openjdk.java.net/jdk9/jdk9/jdk/file/tip/test/javax/swing .

These tests are run using the jtreg tool. You can learn more about it here: http://openjdk.java.net/projects/code-tools/jtreg/intro.html
