VS Code Karma Problem Matcher
Description
Capture errors from Karma tests running in Visual Studio Code.

Usage
After installing this extension, in the "problemMatcher" field in tasks.json, specify "$karma-jasmine2" and "isBackground": true.
Jasmine 2 is installed by default by Angular; if you have upgraded to Jasmine 3, specify "$karma-jasmine3" instead.
For example:
{
// See https://go.microsoft.com/fwlink/?LinkId=733558
// for the documentation about the tasks.json format
"version": "2.0.0",
"tasks": [
{
"label": "Start Live Unit Tests",
"type": "npm",
"script": "test",
"group": "test",
"isBackground": true,
"problemMatcher": "$karma-jasmine2"
}
]
}
