Build failing because of test TestDuplicatesAndScore

[Dario Salvatore Romano]

Hello, I've tried to run the mvnassembly script, but it fails on the test "net.sf.robocode.test.robots.TestDuplicatesAndScore".

The stacktrace of the error is:

run(net.sf.robocode.test.robots.TestDuplicatesAndScore)  Time elapsed: 0.614 sec  <<< FAILURE!

java.lang.AssertionError:

Expected: is "sampleteam.MyFirstLeader (1)"

     but: was "sampleteam.MyFirstLeader (2)"

I've tried to run the command with openJDK 8 first, but then saw that you recommended the Oracle JDK 8, which then produced the same error for me.

Is this a problem on my end, or could there be a bug somewhere?

Thanks in advance.

Unfortunately, the unit tests does not always run consistently across different systems. I use them when building new distribution files. But you don't have to if you just want to play around with the code. :-)

You could disable this single test. But you could also disable all the tests.

In order to disable the test, just change the mvnassembly.cmd (Windows) or mvnassembly.sh (Linux/MacOS):

Change this line:

mvnw clean install ant:ant -DskipTests=false

...into this:

mvnw clean install ant:ant -DskipTests=true

I hope this helps. :-)
