Subject [jira] [Created] (KAFKA-8024) UtilsTest.testFormatBytes fails with german locale
Date Fri, 01 Mar 2019 10:06:00 GMT
Patrik Kleindl created KAFKA-8024:
-------------------------------------

             Summary: UtilsTest.testFormatBytes fails with german locale
                 Key: KAFKA-8024
                 URL: https://issues.apache.org/jira/browse/KAFKA-8024
             Project: Kafka
          Issue Type: Bug
            Reporter: Patrik Kleindl


The unit test fails when the default locale is not English (in my case, deAT)

assertEquals("1.1 MB", formatBytes((long) (1.1 * 1024 * 1024)));

 
org.apache.kafka.common.utils.UtilsTest > testFormatBytes FAILED
    org.junit.ComparisonFailure: expected:<1[.]1 MB> but was:<1[,]1 MB>
        at org.junit.Assert.assertEquals(Assert.java:115)
        at org.junit.Assert.assertEquals(Assert.java:144)
        at org.apache.kafka.common.utils.UtilsTest.testFormatBytes(UtilsTest.java:106)
 

The easiest fix in this case should be adding
{code:java}
jvmArgs '-Duser.language=en -Duser.country=US'{code}
to the test configuration
