Supporting JUnit 5 in Visual Studio Code

After supporting the widely adopted JUnit 4 with the Java Test Runner extension for Visual Studio Code, we’ve received suggestions to add additional test frameworks, like JUnit 5 and TestNG. We’ve added initial support for JUnit 5, including running, debugging test cases as well as test report. Please give us a try and let us know your feedback.

Expression Evaluation based Conditional Break Point

After introducing expression evaluation in our January release for the Java debugger extension, we are bringing the functionality to conditional break points. Now, you can set your breakpoint to break when an expression evaluates to true. We believe this could be a very useful feature when debugging your Java application using Visual Studio Code.

Other Updates

We’ve also added new features to our Java on Visual Studio Code extension lineup, including:

Java Test Runner

Trigger tests from test explorer on different levels

Add command to open log file

Add setting to specify the position of test report

Tomcat

Add several context commands in Tomcat Explorer

Add support for JVM customization and Tomcat server configuration

Add command palette entries for user input

Maven

Add support for auto-update maven project explorer when pom.xml is updated

Try it out

Please don’t hesitate to try Visual Studio Code for your Java development, and let us know your thoughts! Install the Java Extension Pack which includes Language Support for Java by Red Hat, Debugger for Java, Maven, and the Java Test Runner.

Additional resources

If you’re working on Spring Boot, there are also extensions for Spring Boot Tools and Spring Initializr we’ve developed in partnership with Pivotal.

Emmet 2.0 in Visual Studio Code

August 7, 2017 Ramya Rao, @ramyanexus

In the July 2017 release of Visual Studio Code (version 1.15), we're shipping a better Emmet experience which has been in preview for the past 2 releases.

It's features include:

Emmet abbreviation expansions in suggestion/auto-completion lists.

Multi-cursor support for most Emmet actions.

Updated support for custom Emmet snippets.

As part of this update, we have re-written all of the Emmet actions using new npm modules from @emmetio.

An important change is that the Tab key is no longer the dedicated keyboard shortcut for expanding Emmet abbreviations. Instead, Emmet abbreviations will now appear in the suggestion list. They can be selected like any other smart completion and on selection, the abbreviation will be expanded.

This may take some getting used to but we think you'll see the benefits of Emmet abbreviations being treated as suggestions or smart completions. You can still bind any keyboard shortcut (other than Tabkey) to the editor.action.emmet.expandAbbreviation command or use Emmet: Expand Abbreviation from the Command Palette.

Read on to learn about the Emmet 2.0 changes in Visual Studio Code.

Visual Studio Modeling SDK is now available with Visual Studio 2017

You might want to use the Visual Studio Modeling SDK if you have one of these requirements:

Create Graphical or Form-Based modeling designers. For these, you can use the DSL Tools

Enable transformation of T4 templates part of the build. For these you can use the T4 SDK

Bulk-index assemblies in the Code Index underlying Code Map. For this you can use the Code Index SDK (embedded in the Modeling SDK)

The Modeling SDK changed its name several times during the last ten years: starting from the ‘DSL Tools’ in 2007, it grew to become ‘Visualization and Modeling SDK’ (VSVm SDK) in 2010. At that time, the SDK also contained UML extensibility. Finally, the name was a bit long and therefore it was shorted to ‘Modeling SDK’ in 2012. With previous versions of Visual Studio, regardless of its name, we used to release the Modeling SDK as a separate download.

We are pleased to announce that, from this Visual Studio 2017 RC update, the Visual Studio Modeling SDK will be released as part of Visual Studio itself (in all editions of Visual Studio).

How to install the components of the Modeling SDK?

Previously, the DSL Tools, T4 SDK and Code Index SDK were all shipped as part of the Modeling SDK.

In VS2017, the T4 SDK is installed with the T4 runtime as part of the Text Template Transformation optional component, which is itself installed by default with many Visual Studio workloads

The DSL Tools and Code Index SDK are installed as part of the DSL tools optional component (the component will be renamed to the Modeling SDK in a future Visual Studio RC update, as this is the name under which you have known it for several years). you can find this component in the Visual Studio Extension development workload in every edition of Visual Studio.

Known issues

For the next update of Visual Studio 2017 RC we are slightly improving the experience:

When you use the “Add New Project …” dialog, the DSL Tools project template is currently located under “Other Project Types | Extensibility”. And now, it’s the only one in this category. We are moving it to be under “C# | Extensibility” with the other Visual Studio SDK content, where it makes more sense.

The DSLProjectMigrationTool, (which transforms a DSL Tools solution created for previous versions of Visual Studio, to Visual Studio 2017) will also be added to the release.

You want to know more?

You can find more information on these features:

DSL Tools are described in detail in the MSDN Library (Modeling SDK for Visual Studio – Domain-Specific Languages). One change is you won’t need to install the Modeling SDK any longer. The DSL Tools Lab is a good resource for beginners.

T4 MSBuild is also described in the MSDN Library (https://msdn.microsoft.com/en-us/library/ee847423.aspx). Again, you can skip the first step as you won’t need to install the Modeling SDK any longer.

The Code Index SDK is detailed in the following blog posts: https://blogs.msdn.microsoft.com/vis...ag/code-index/
