Assert.isTrue 用法

 String shippWay = "MM";

boolean expression = shippWay.equals(ShippingWayEnum.ZT.getCode());
System.out.println("Assert.isTrue报错");

 shippWay = "ZT";
 expression = shippWay.equals(ShippingWayEnum.ZT.getCode());

System.out.println(" Assert.isTrue 不报错");

String status = "600";
expression = status.equals("600");

System.out.println("600==600  Assert.isNotTrue 报错");

BigDecimal requestQty = new BigDecimal(10);
BigDecimal total = new BigDecimal(10);
expression = requestQty.compareTo(total) > 0 ;

System.out.println("a>b  Assert.isNotTrue 不报错");
