Support for code coverage for ASP.NET 5 projects.

Support for code coverage for ASP.NET 5 projects.

We can run the test in ASP.NET 5 using dnx . test command, where . is the current directory, where we require the project.json file. So I am the command like this.

OpenCover.Console.exe -target:C:\Users\Anuraj.P\.dnx\runtimes\dnx-clr-win-x86.1.0.0-beta5\bin\dnx.exe -targetargs:" . test" -output:coverage.xml

You can find the source code and test project - https://github.com/anuraj/ASPNET5CIDemo

If you want to configure DNX, please check the appveyor.yml or .travis.yml

Thanks, what version of OpenCover are you using? The latest release can be found here https://github.com/OpenCover/opencover/releases if you need it.

In the meantime what does it say in the XML about where it loaded the assembly from and why it didn't instrument it?

[scotroach]

I too have the same problem.
The projects are the new ASP.NET 5 - XProj.
In the xml says it was skippedDueTo="MissingPdb"

OS.Core.dll
OS.Core

I am also having the same problem, using dnx-clr-win-x86.1.0.0-beta6.
Output file says it was skippedDueTo="MissingPdb" in dlls of project and hash attribute is empty.
Is there another way to inform the path of the pdb file?

[sawilde]

-targetdir: may work for you

the original OP did not respond to my query so I have not pushed on the support

[gBritz]

Thanks for your suggestion.
I tried to use the -targetdir:, but i had another error.
You can check here
Have you any sample project with dnx to base me?

[sawilde]

Have you any sample project with dnx to base me?

Sorry I don't, what you could try is using the full path to the targetdirectory.

[anuraj]

It tried the latest version. opencover.4.6.192.msi, XML says skippedDueTo="MissingPdb".

[Cobster]

I think I got it figured out. Specify the --lib argument with the dnx command that targets the folder containing the PDB of the assembly being covered.

For instance here is my command:

OpenCover.Console.exe -target:C:\users\jbruun.dnx\runtimes\dnx-clr-win-x86.1.0.0-beta6\bin\dnx.exe -targetargs:"--lib c:\projects\cpip\src\website\bin\debug\dnx451 c:\projects\cpip\te
st\Website.Tests. test" -output:coverage.xml -filter:+[Website]*

@Cobster
Great awesome.
Thanks, your suggestion really works.
Build with coverage here

[anuraj]

It is working for me, but the results include XUnit assemblies as well. If I include filter option the report is not getting generated.

[sawilde]

@Cobster thanks - I'll add it to the wiki and documentation

[Cobster]

@sawilde - Your welcome, glad this could get figured out without requiring new bits.
@anuraj - Does the lib folder you are targeting contain the PDB? I've had to use the dnu build from the command line to get the dll and pdb created, a simple build in visual studio doesn't seem to generate the artifacts.

[anuraj]

Yes. I have the DLL and PDB. But I didn't understand why filter option is not working. If I apply filter:"-[XUnit*]*" - It is not generating the report :(

[Cobster]

@anuraj - Not sure if its case sensitive, but if it is the XU in XUnit should be lowercase to match the assembly name. Are you adding the asterisk wildcard after [xunit] so it will filter the types?

I've had better luck using the inclusion filter to specify my own assemblies.

[sawilde]

@anuraj add +[*]* opencover filters have a default set but when you supply your own then it is exclusive by default this is so we don't bring in coverage for 3rd party assemblies and the runtime, which may skew your results and make it very, very slow.

as @Cobster mentions the inclusive way is much easier and you are much more in control e.g.

-filter:"+[MyCompanyName*]* -[*Tests]*"

which you include all the assemblies beginning with MyCompanyName but exclude any that have Tests at the end.

All of this is in the wiki usage guide

Added wiki entry https://github.com/OpenCover/opencover/wiki/DNX-Support

[sgopimca7]

When the code reads the value from configuration file such as scenarios like reading connection string from database, then it always throws null exception and all test methods are fail.
I am using the opencover with MSTest Test methods. Actually all test methods works fine in local, but when i run through the opencover, then the test methods which has the code to read configuration from app.config are always fails.

[sawilde]

@sgopimca7 Please open a new issue with a repeatable scenario

[abhimanyuk453]

i am facing similar issue where for my project .net framework 4.6.2 hosted in iis ,i am unable to generate xml file for my project.
Command used is : OpenCover.Console.exe -target:C:\Windows\System32\inetsrv\w3wp.exe -targetargs:-debug -targetdir:C:\inetpub\wwwroot\coverage\bin\ -register:user
could you please help me with this issue. @sawilde
