Here, you're setting the text attributes to the same column of the list 
store. It should be:

test_col [0] = gtk_tree_view_column_new_with_attributes ( "test0", 
renderer, "text", 0, NULL );
test_col [1] = gtk_tree_view_column_new_with_attributes ( "test1", 
renderer, "text", 1, NULL );

so that the first column of the GtkTreeView will show the text from the 
first column of the GtkListStore, and the second column of the 
GtkTreeView will show the text from the second column of the GtkListStore.
