Comparing unicode characters in Junit

I had problems in some flow with unicode chars in some of my flows. So i fixed the flow and added a test.

assertEquals("Björk", buyingOption.getArtist());

the buyingOption.getArtist() will return the same name that is on ,here is a snippet :

but junit will fail with the message :

junit.framework.ComparisonFailure: null 
Expected :Bj?rk
Actual   :Bj?rk

This is probably due to the default encoding used for your Java source files. The ö in the string literal in the JUnit source code is probably being converted to something else when the test is compiled.

To avoid this, use Unicode escapes (\uxxxx) in the string literals in your JUnit source code:

assertEquals("Bj\u00F6rk", buyingOption.getArtist());

I agree with Grodriguez but would like to suggest you to change your default encoding to UTF-8 and forget about this kind of problems.

How to do this? It depends on your IDE. For example in Eclipse go to Window/Preferences then type "encoding", choose Workspace and change encoding to UTf-8

I found the solution was to change the default encoding before running mvn test

My fix to this issue was to set the ENV var JAVA_TOOL_OPTIONS before running

export JAVA_TOOL_OPTIONS="$JAVA_TOOL_OPTIONS -Dfile.encoding=UTF8"    
mvn test
