Hello, thank you very much for your help. You are giving me the exact
answer I needed, but I am unable to see the output after ->Run as -> JUnit
Test.
When I right click on ALSWRFactorizerTest.java , I get the Run
Configuration window. Here I select test runner: JUnit 4,
the Project is mahout-examples
Test class : org.apache.mahout.clustering.display.ClustersFilterTest
Test Method : (All methods)
I click Run
Then I get a Errors in Workspace message saying that :
Errors exist in required project(s):
mahout-integration, mahout-examples, mahout-core, mahout-math
Proceed with launch?.
After proceeding, JUnit window says : runs 2/2, Errors:0, Failures: 0
My question might seem silly to you, but I have no idea about it, How to
view the test results?
Also could you tell me where can I change the log level to 'info' or
'debug'.
I was not able to run in debug mode with breakpoints.
Thank you very much. I would really appreciate little more support from you
until I figure things out how to debug the code.
