[JENKINS-51392] JUnit Health report amplification factor ignored in matrix projects

When using a matrix project, the weather report always uses a factor of 1.0 for test results, regardless of the Health report amplification factor configured in the job.

A factor of 0 also does not disabled test health reporting as advertised.

Steps to reproduce

1. Create a new Multi-Configuration Project.


2. Add an arbitrary (e.g userdefined) axis with one or more values.


3. Add a build step that creates a JUnit result file:

   ```

   
   
   
   This test failed.
   
   

   ```



4. Add Publish JUnit post-build action.


5. Set Health report amplification factor to any value other than 1.0.


6. Run the project.


7. Observe the weather report.

Raw content of original issue

When using a matrix project, the weather report always uses a factor of 1.0 for test results, regardless of the Health report amplification factor configured in the job.


A factor of 0 also does not disabled test health reporting as advertised.

Steps to reproduce



	
Create a new Multi-Configuration Project.

	
Add an arbitrary (e.g userdefined) axis with one or more values.

	
Add a build step that creates a JUnit result file:



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

<testsuites>

   <testsuite errors="0" failures="1" name="" skipped="0" tests="2">

      <testcase classname="test" name="success" />

      <testcase classname="test" name="failure">

         <failure>This test failed.</failure>

      </testcase>

   </testsuite>

</testsuites>



	
Add Publish JUnit post-build action.

	
Set Health report amplification factor to any value other than 1.0.

	
Run the project.

	
Observe the weather report.

environment

```
Jenkins ver. 2.107.3

Matrix Project Plugin 1.13

JUnit Plugin 1.24
```

Reproduce the matrix project with the supplied JUnit XML and a non-1.0 amplification factor, using the listed Jenkins, Matrix Project Plugin, and JUnit versions as a baseline. Trace the matrix project's JUnit publishing and weather-report path; done means the weather report reflects the configured factor and factor 0 disables test health reporting.
