change default locale for junit test

Anonymous User 3242 29 Dec 2014
How do you change the default locale for a JUnit Test. Current locale is en. I want to test for es_ES. I tried:

System.setProperty("locale", "es_ES");
But this doesn't seem to work.

You can set the default Locale with Locale.setDefault.

Sets the default locale for this instance of the Java Virtual Machine. This does not affect the host locale.

Locale.setDefault(new Locale("es", "ES"));
Testing with the following resource files:

test.properties

message=Yes
test_es_ES.properties

message=Sí
Here is my main function, with no change to my default locale (en_US):

public static void main(String[] args)
{
    ResourceBundle test = ResourceBundle.getBundle("test");
    System.out.println(test.getString("message"));
}
Output:

Yes
Here is my main function, with a change to your test locale (es_ES):

public static void main(String[] args)
{
    Locale.setDefault(new Locale("es", "ES"));
    ResourceBundle test = ResourceBundle.getBundle("test");
    System.out.println(test.getString("message"));
}
Output:

Sí
This should work when applied to a JUnit test case.
