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:
- Add simple infrastructure to write Groovy Hints: https://github.com/apache/incubator-netbeans/pull/902
- Add trait support for Groovy: https://github.com/apache/incubator-netbeans/pull/901
- First stab at flow typing: https://github.com/apache/incubator-netbeans/pull/903
OpenJDK
- Automatically detect JTReg from OpenJDK configuration: https://github.com/apache/incubator-netbeans/pull/925
- Register the expanded JDK as a Java Platform: https://github.com/apache/incubator-netbeans/pull/918
- Various improvements to make the OpenJDK project work better: https://github.com/apache/incubator-netbeans/pull/897
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.
