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"
        }
    ]
}

Thanks:

Enjoy!
