PathTooLongException

PathTooLongException

Hello! Ive run into problems with building codecoverage on my test assemblies. The problem is pretty simple. Im using msbuild task and I really don`t want to develop all my unit tests as one .Net project. This is my script: For start all were looking good. Now when we have created 3rd unit-tests project there is exception: Target CoreBuildNCoverUnitTests: NCover.Console v2.0.4 (x86) - Code Coverage Analysis for .NET Copyright (c) 2003-2007 Gnoso Inc. http://www.ncover.com

Any ideas how to avoid this? One solution could be running NCover on every assembly separately, but I need metrics on all unit tests. So for that I could run NCoverExplorer task but I suppose there will be similar exception when I`ll add to arguments all my .xml results. Now NCover starts to show his bad sides. Please help!

RE: PathTooLongException

narcomancer,

it looks like you're passing in the test assemblies as a list of items separated by semicolons when mbunit expects them to be separated by spaces. try replacing the semicolons in your test assembly list with spaces.

RE: PathTooLongException

sporewell,

Thank You, this helped me much. I`ve created new msbuild task which converts item to property with specific delimiter so I have working automated codecoverage again!
