    replay();
    SymbolProvider p = new ServletContextSymbolProvider(context);
    assertEquals(p.valueForSymbol(key1), value1);
    assertEquals(p.valueForSymbol(key2), value2);
    // Not in config is null
    assertNull(p.valueForSymbol("wilma"));
    // Check for case insensitivity
    assertEquals(p.valueForSymbol("FRED"), value1);
    verify();
