Miscellaneous Features

As the code donations from Oracle keep coming in, they are being integrated into NetBeans. NetBeans 10.0 will see the return of Javascript and Groovy, as well as the addition of JUnit 5.

JavaScript: https://github.com/apache/incubator-netbeans/pull/882

Modules in the "webcommon" cluster are included in Apache NetBeans for the first time. I.e., all JavaScript features in Apache NetBeans GitHub are part of Apache NetBeans 10.

Groovy: https://github.com/apache/incubator-netbeans/pull/904

Modules in the "groovy" cluster are included in Apache NetBeans for the first time. I.e., all Groovy features in Apache NetBeans GitHub are part of Apache NetBeans 10.

Plus:

OpenJDK

JUnit 5: https://github.com/apache/incubator-netbeans/pull/892

With NetBeans existing JUnit and Maven integration, the introduction of JUnit 5 didn't need much work, as in a lot of cases, NetBeans defers to Maven, and in particular the Maven Surefire plugin to execute tests. No work has been implemented for Ant specific JUnit 5 integration.

New JUnit 5 Library

Introducing support for JUnit 5.3.1 a new Library has been added to NetBeans.

Default version of JUnit when creating Java 8+ applications

When working with a Maven based Java 8+ project with no existing tests, or test framework defined in the project pom file, the IDE will use JUnit 5 as the default JUnit version, and add in the appropriate dependencies.

Support for Run / Debug Focused Test Methods

JUnit 5 introduced a new @Testable annotation, any method that includes an annotation that inherits from this, will be allowed to be executed with these action menu items.


New JUnit 5 Test Template

Default JUnit 5 Test Template provided out of the box. Note JUnit 5 doesn't currently support test suite's for its Jupiter engine, so the template provided will attempt to create a test suite using the Vintage engine. 

Updated IDE Hints for JUnit 5's Assertion class

Introduced updated assertArrayEquals hints to support JUnit 5 as the method signatures have changed since JUnit 4.

PHP

A big addition to NetBeans 10 is that it will once again support PHP. Features will include support for PHP 7.0 through 7.3, PHPStan and Twig, as well as editing and debugging enhancements.

All the PHP support for NetBeans 9 was contributed by our NetBeans user Junichi Yamamoto.
