Filter HTML reports to only show coverage results below a certain percentage

[bryansonofpatt]

Hello,
We use the Report Generator in our Azure DevOps pipeline. The output type is HtmlInline_AzurePipelines. We have a lot of classes we would like to ignore in the report whose coverage is above a certain percentage (90%).

I don't see a simple way to pass params to the Report Generator task to accomplish this. The only way I see is if someone wrote a custom plugin and put a % threshold in the CreateSummaryReport method of the IReportBuilder implementation. Am I correct in this assumption, or did I miss anything.

Thank you!
Bryan

Hi Bryan,

there is currently no way to filter classes based on their coverage.
I think a dynamic filter (e.g a slider) in the HTML report might be a good idea.

Only problem is, that this would not work within Azure DevOps, since JavaScript is blocked here.
It only would work if you download the report.

Release 5.3.0 now contains range sliders to dynamically filter classes based on coverage

I ran v5.3 and still don't see the sliders. I also added 'publishCodeCoverageResults: true' param and removed 'PublishCodeCoverageResults' task.

This only works outside the Azure DevOps "Code Coverage" tab.
Azure DevOps blocks all JavaScript and therefore the dynamic filtering.

Here's a sample report: https://reportgenerator.io/resources/reports/HtmlInline_AzurePipelines/index.html

Good to know about the JavaScript in ADO.
I downloaded all of the report artifacts that the tool generated and opened them in my browser. I did get some JavaScript - Collapse/Expand all, Grouping slider, column sorting, and Filter. I still do not see the percentage sliders though. Am I missing a param or config setting?

The screenshot indicate that you are not using the latest version 5.3.0.

Are you sure that the PublishCodeCoverageResults task has been removed?

If not, the report may get regenerated. See this wiki page for details:

oops! On my last pipeline run, I forgot to pick my POC branch.
We're good now!!! Thanks!
