PowerMock testing - set static field of class

Question

I\'m having difficulty finding a way to set a static field of a class. It\'s basically like this:

public class Foo{
    // ...
    private static B b = null;         


        

Answer 1

You can use getAllStaticFields and try to set them

Example:

YourFieldClass newValue;
final Set fields = Whitebox.getAllStaticFields(YourClass.class);
        for (final Field field : fields) {
            if (YourFieldClass.class.equals(field.getType())) { // or check by field name
                field.setAccessible(true);
                field.set(YourClass.class, newValue);
            }       }
