how to generate trend file in Nant Script

Hi Guys, I am stuck with another problem. I need to generate trend file and finally append to the full coverage report.

I have used trendFile & appendTrendTo, but it didn't work.

Any help is appreciated!

My Nant script looks like this ....

. ....

What is the correct attribute for trendfile generation.

RE: how to generate trend file in Nant Script

'coverageTrendPath' is the currect attribute to use in place of 'trendFile'

RE: how to generate trend file in Nant Script

apologies. 'coverageTrendPath' is for the >ncoverreporting /> property.

'appendTrendTo' is the property on the task

RE: how to generate trend file in Nant Script

Hi Sporewell,

As suggested by you , i tried appendTrendTo = "C:\trends.trend" but i got following error...

BUILD FAILED

C:\Copy of Downtime.build(8,4): Unexpected attribute "appendTrendTo" on element .

Please help ...

RE: how to generate trend file in Nant Script

which version of the build task assemblies are you using? The attribute should be available on every version after 3.0.15, as long as the assembly is named "NCover.NAntTasks.dll"

RE: how to generate trend file in Nant Script

I am using 3.2.4.5844 assemblies. My script looks like this...

<?xml version="1.0" encoding="utf-8"?>

....

....

cmd ....

Buildfile: file:///C:/Copy of Downtime.build Target framework: Microsoft .NET Framework 2.0 Target(s) specified: coverage

[loadtasks] Scanning assembly "NCoverExplorer.NAntTasks" for extensions. [loadtasks] Scanning assembly "NCover.NAntTasks" for extensions.

coverage:

BUILD FAILED

ah. The task is provided in ncover 3 for backward compatibility. The task supports all of the new stuff in 3; you can find all of the options for the task here

RE: how to generate trend file in Nant Script

Thanks, Now i can generate trend file using coverageTrendPath and the trend graph is appearing in reports. Problem is the trend file doesn't have any trend. Nothing is coming except an empty trend graph for different coverage metrics.

Script used ...

<coverageFilters>
    <filter pattern="*.Tests" type="Assembly" isRegex="true"  isInclude="false" />
    <filter pattern="*.Tests*" type="Namespace" isRegex="true"  isInclude="false" />
    <filter pattern="*_UnitTests*" type="Class" isRegex="true"  isInclude="false" />

</coverageFilters>

Thanks,

If you load the trend file into NCover Explorer, do you see trends?

RE: how to generate trend file in Nant Script

Hi Sporewell,

Yes i can see the trends when i load trend file into Explorer.

RE: how to generate trend file in Nant Script

Is your problem resolved or do you need additional help with your Nant script?

Thanks

RE: how to generate trend file in Nant Script

Hi Joe,

I want to do it using cmd line. So once i run my Nant Scripts, reports are generated but i can't see trend in trend graph. Trend graph is present in Full Coverage Report but w/o any statistics. This is for only trend graph.

Though i can use explorer to see these trends in trend graph, but the user will not be having ncover explorer to load and see.

Please help!!!

RE: how to generate trend file in Nant Script

could you explain further "Trend graph is present in Full Coverage Report but w/o any statistics" because I'm not sure I understand it fully.

RE: how to generate trend file in Nant Script

Hi Sporewell, I mean to say that the graph is present in report but with no values(actual X and Y values). But when i load the same trend file into explorer i can see dots(green and red) indicating X-Y axis values.

I hope this make sense.

Thanks,
