Cannot run or debug unit tests from within VSCode 3

I can run unit tests from the terminal with

mage/Mage.Tests % mvn '-Dtest=LicidAbilityTest' test

But I can’t use VSCode’s test runner integration to run tests. I’d like to have access to the VSCode debugger here…

Repro:

1. Set up VSCode with Mage as specified in README.md:

// .vscode/launch.json
{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "java",
            "name": "Debug (Launch) - Current File",
            "request": "launch",
            "mainClass": "${file}"
        },
        {
            "type": "java",
            "name": "Run Client",
            "request": "launch",
            "mainClass": "mage.client.MageFrame",
            "projectName": "mage-client",
            "cwd": "${workspaceFolder}/Mage.Client"
        },
        {
            "type": "java",
            "name": "Run Server",
            "request": "launch",
            "mainClass": "mage.server.Main",
            "projectName": "mage-server",
            "cwd": "${workspaceFolder}/Mage.Server"
        }
    ]
}

// .vscode/settings.json
{
    "files.exclude": {
        "**/.classpath": true,
        "**/.project": true,
        "**/.settings": true,
        "**/.factorypath": true
    },
    "java.configuration.updateBuildConfiguration": "interactive"
}

1. Click the “Run Test” link above LicidAbilityTest. Nothing happens…
2. View “Java Test Runner” output console, see

org.mage.test.cards.abilities.activated.LicidAbilityTest.Failed to parse the message: %ERROR  1

1. Change MageTestPlayerBase to extend junit.framework.TestCase
2. Rename CopyGameStatePerformanceTest.run to CopyGameStatePerformanceTest.go to avoid the name conflict and fix the build
3. Click “Run Test” above LicidAbilityTest. Now the test runs, but it doesn’t initialize playerA and we get a NullPointerException…

You don’t need to change any code. Try to research first error. It’s can be missing database files (game test needs db files). Run full tests from maven command line (it’s will create all missing db) or copy-paste db folder from \Mage.Server\db or \Mage.Client\db folder to \Mage.Tests\db (or any other folder like \Mage.\Verify\db – it’s depend on your test).

Thanks, works for me!
