Using NCrunch Console Tool v2.9.0.3

I have a couple of issues trying to get our solution up and running with NCrunch on TeamCity. Below is NCRunch errors I noticed when running the console tool explicitly via command prompt.


When running via TC I get a lot of failed tests with non-helping output nor stacktrace as
Code:

------ Stdout: -------
 text

(When looking at build log it seems it cannot find a required file, I guess this is part of setup routine but it would be helpful if that could be determined via test output and not requiring download full build log to investigate).

Try 1 was cancelled and then Try 2 was run until end.

Code:

Try 1:

Hi, thanks for sharing these issues.

Most of these exceptions are connectivity related. NCrunch does log connectivity problems (as sometimes these are useful), and it will automatically try to reconnect if it encounters them. Can you confirm that you have clear and trouble-free connectivity from the machine running the console tool into the grid nodes it is configured to use?

The two NUnit exceptions are very interesting. I've been trying to analyse what kind of situation could cause this, and I wonder if it may be due to an inconsistency with how these tests were discovered vs how they were run. What do you usually use for your 'Framework utilisation type for NUnit' setting? Have you ever had this set to StaticAnalysis? Does clearing out the NCrunch cache make any difference here?

They do connect fine when using same config via vstudio and seems to be temporary.

I already use static for the console tool in order to try speed things up (and not get 1 test "per test case" to more closely be comparable with TC's built in NUnit test runner).

I have not reproduced the errors but if they appear again and are consistent I will try this and see if it helps. The cache is reused between console tool executions I guess? So to get proper test results I should always clear this when running on e.g. TeamCity? (I was confused the test output said it was running several thousands of tests while in fact I only had selected 6 via engine mode to be run, which was also reflected in console output).

This is very interesting. The NUnit exceptions suggest that the console tool is trying to run these tests using DynamicAnalysis. The setting can only be applied at solution level, so there must be an inconsistency somewhere. Let me know if you find a way to reproduce this.

The console tool will re-use the cached the data in the same way as the VS addin. There's normally no need to clean it out, and doing so will greatly increase the overall time to perform an execution run. I merely wondered if the Static/Dynamic analysis issue could be related to stale data within the cache ... which is something that should be impossible, but was worth investigating to be sure.

Make sure that you choose the engine mode to run using the console tool command-line parameter. I don't think it will consider the engine mode you have/had selected in Visual Studio. The engine mode filter should prevent the tool from running tests that you've excluded.
