JSTestAdapter

JSTestAdapter is a JavaScript test adapter extension for Visual Studio Test Platform. JSTestAdapter with vstest can be used as a command line tool to run tests written in mocha, jasmine or jest.

Install

npm install --save-dev jstestadapter

Usage

# Testing with default test framework, Jasmine
path/to/vstest.console.exe --Inisolation --TestAdapterPath:./node_modules/jstestadapter/ path/to/test.1.js path/to/test.2.js

# Testing with Mocha
path/to/vstest.console.exe --Inisolation --TestAdapterPath:./node_modules/jstestadapter/ path/to/test.1.js path/to/test.2.js -- JSTest.TestFramework=Mocha

# Running tests with jest
path/to/vstest.console.exe --Inisolation --TestAdapterPath:./node_modules/jstestadapter/ path/to/package.json -- JSTest.TestFramework=Jest

Due to a current bug in vstest the switch --Inisolation is required to run JSTestAdapter.

RunSettings Configuration

Option	Usage	Default
TestFramework	One of the following test frameworks for execution: Jasmine/Mocha/Jest	Jasmine
DebugLogs	Enable debug logs for JavaScript test runner	false

RunSettings can be provided through the the vstest cli itself:

vstest.console.exe --Isolation --TestAdapterPath:<path> <files> -- JSTest.DebugLogs=true JSTest.TestFramework=mocha

Using RunSettings xml defined for vstest:

vstest.console.exe --Isolation --Settings:RunSettings.xml --TestAdapterPath:<path> <files>

With RunSettings.xml:

<RunSettings>
    <JSTest>
        <TestFramework>mocha</TestFramework>
        <TestFrameworkConfigJson>{
            "timeout": 60000,
            "slow": 30000
        }</TestFrameworkConfigJson>
        <DebugLogs>true</DebugLogs>
