Mocha tests discovered but do not seem to run

[frauss]

I'm trying to move a Node.js project I created using WebStorm to Visual Studio and am having problems running Mocha unit tests.

When I try to 'Run all...' from the test explorer it seems build and run something but not my tests.

Here's the output I get:

Processing finished for framework of Mocha
========== Run test finished: 10 run (0:00:23.7025712) ==========

However, I receive none of the console output I would expect from my tests.

I imagine something is misconfigured but just not sure what.

Thanks,
Fred

Is the test framework property set to mocha in file properties?

[frauss]

Yes.

I see the tests in the test explorer:

However when I try to run or debug them they don't seem to run and I'm not
seeing anything in the output indicating where the problem is.

Thanks. What happens if you set a breakpoint on the first line of one of the tests, and right click > debug in test explorer? Does it run or hit the breakpoint? What if you add a console.log to the test? Does it show up in the Output after running the tests? (see screenshot below) Do you have a simple example that reproduces the issue?

[frauss]

No, it never hits the breakpoint. Here's the the results:

Test Name: keystoneModel contentFilter save single should create new
content filter with the name 'Unit Test Filter'
Test FullName: C:\Sources\eAP\DigitalPlatforms\Syndication\Keystone\Node.js\KeystoneDMIngest\test\keystoneModel.Test.js::keystoneModel
contentFilter save single should create new content filter with the name
'Unit Test Filter'::Mocha
Test Source: C:\Sources\eAP\DigitalPlatforms\Syndication\Keystone\Node.js\KeystoneDMIngest\test\keystoneModel.Test.js
: line 0
Test Outcome: Failed
Test Duration: 0:00:01.8910134

Here's the Debug Output window:

The thread 'main thread' (0x1) has exited with code 0 (0x0).

The program '[1] node.exe @ tcp://localhost:65325/#ping=0' has exited with
code -1 (0xffffffff).

I never see a console window that indicates Node is running. Is there a way
to get more detailed output or another window I could check?

Does the same issue occur with the included mocha item templates?

Can you please walk me through the exact steps you're taking, including code snippets? It would be especially helpful to start with a basic console app and see if you can get things working there first.

I encountered the same issue:

Steps:

1. Created a new Project, Node.js -> Blank Node.js Console Application.
2. In solution folder executed, npm install mocha
3. Under Solution, Add Item -> New Item -> JavaScript Mocha UnitTest file.
4. For UnitTest.js, changed Test Framework to Mocha
5. In Test Explorer, right clicked 'Test Suite 1 Test 1' -> Run Selected Tests, Test Passed.
6. Set Breakpoint as below:
   
7. In Test Explorer, right clicked 'Test Suite 1 Test 1' -> Debug Selected Tests, Test Failed.
8. Clicked on Output, got following screen:
   
9. Output of Node.js Tools Live Diagnostics:
   Node.js Tools Live Diagnostics.txt

On a fresh machine and new installation, followed the same above steps, except:
6. In Test Explorer, right clicked 'Test Suite 1 Test 1' -> Debug Selected Tests.
7. The project entered into debug mode, stopping at the breakpoint.
8. On Clicking Continue, test passed with following output:

@mousetraps The issue seems to be with Node.js 4.3.0, upgraded to 4.4, and it works now.

[frauss]

Upgrading to 4.4 definitely fixed the issue. I had previously been running
4.2.6.

Not sure what the issue was but vickymittal thanks for the info!!

@frauss, this was due to bug in nodejs (nodejs/node#4440)

[mjbvz]

Seems like this has a known resolution. Closing this issue.
