browser tests need to be run from command line like pub run test -pdartium. Is there a way to debug such tests.
The Dart team is working hard to make tests with the new test package debuggable. Until the related issues are fixed you can use this workaround:
To run browser tests with the new test package, for example from WebStrom, including debugging, just replace the <x-test-dart ...> tag with a normal Dart script tag pointing to your test file and run it like any Dart browser application from WebStorm.
This also works for Polymer tests. Ensure you run await initPolymer(); or the appropriate initialization necessary for the used Polymer version.
I usually create a copy of the test entry page file where I can keep the replaced script tag.
pub run test -pdartium --pause-after-load
starts the test only after I click a "play" button on the test page. This gives me time to open up Dev Tools in Dartium and set breakpoints. I can also open up the Observatory and do stuff there.

I have an application packaged and signed as an MSIX, it installs and runs from the start menu. I'd like to be able to run the application from the command line too, for automated testing, but I can't see a way to do it. From powershell the docs suggest Invoke-CommandInsideDesktopPackage, but that requires developer mode which I'd rather not enable on test machines, and also is not the same as just running the app. What I'd love is a simple command line command that starts the app in the same way that the start menu does it.
By design, the binaries from an installation folder of an MSIX folder are not directly accessible through their direct path.
The correct way to run an app from the command line from an MSIX package is with the use of an execution alias. The following article contains more details about how an execution alias works and how you can define it in your package, no matter the tool you use to build the MSIX package.

I'm using pub serve to run my page. I noticed that there are tools like lite-server for npm, that make sure that after file contents are changed, the web page is automatically refreshed.
Anyone got something like that working for dart using pub serve? I thought maybe some grinder script with the watcher package could make that work?
Pub should handle monitoring and autodeployment of changes itself when run in debug or release mode.
You can verify this works correctly by issuing from your project root
pub serve
then make a change to a html or dart file and verify that the project is automatically rebuilt.
If this is not working, you might try experimenting with the --force-poll option when running pub serve. Per documentation:
--[no-]force-poll Force the use of a polling filesystem watcher.
We are currently working on getting better code coverage for one of our JS libraries. I have the The Intern up and running, and can run tests in the browser. However, our libraries create DOM elements in some of their functions, making it so we can't run JUnit from the terminal because Node.js doesn't allow for DOM construction in tests. Is there a way we can get JUnit code coverage on the html and console output we get when we run The Intern in the browser?
I found the answer. From this link: https://theintern.github.io/intern/#local-selenium
Using ChromeDriver (Chrome-only)
If you’re just looking to have a local environment for developing functional tests, a stand-alone ChromeDriver installation works great.
1. Download the latest version of ChromeDriver
2. Set tunnel to 'NullTunnel'
3. Run chromedriver --port=4444 --url-base=wd/hub
4. Set your environments capabilities to [ { browserName: 'chrome' } ]
5. Run the test runner
Once you have that setup and running, you can run
node_modules/intern/bin/intern-runner.js config=tests/intern reporters=JUnit filename=junit.xml
This will allow the tests to run in a chrome instance, and then output the results to a report that can then be upload somewhere.
I just follow https://www.dartlang.org/docs/dart-up-and-running/ch01.html to run a Dart console application,but the result is ‘HTML file could not be found’.
If you want to know how to start it from DartEditor, just right-click the file in the Files view and choose Run. If you click the Run button in the toolbar, probably the previously launched file is launched (didn't use DartEditor since 1/2 year)
If you want to launch it from command line just run dart bin/main.dart
I installed dart-sdk and downloaded dart plugin to Phpstorm 8.0.3, but I cant figure out how to transpile dart to js. When I am trying to make file watcher I dont have any Dart2Js predefined template in settings.
Thank you
I know only WebStorm 9 and 10. Maybe you can still derive how it might work in PHPStorm.
Usually you don't want to build to JavaScript on each file change because this would slow your machine down.
During development you use pub serve which is automatically launched by WS 9 and 10 and which transpiles Dart files to JavaScript only on demand (when requested by a browser) and only compiles what it didn't compile previously.
For deployment WebStorm can use the Pub: build ... context menu of the pubspec.yaml file in the project view.
See #Günter Zöchbauer answer.
Using dart2js is not the recommended approach, as it runs on file level instead of project, creates output in the src folder, etc. - but the main reason is that it is not clear when/why to use it. If you need to build your project, use 'pub build' (available in pubspec.yaml right-click menu). When debugging in browser, 'pub serve' is always used implicitly - it performs all needed transformations...
But, if you still need this watcher, you can easily configure it yourself by adding a watcher of 'custom' type.
