排列在接口测试中的应用

在接口测试工作中，数据的传入顺序，会影响到测试结果，于是需要对接口参数进行排列操作。可以使用排列组件Permutation对参数集合进行排列操作

引入组件依赖：

<dependency>
<groupId>org.raistlic.lib</groupId>
<artifactId>commons-core</artifactId>
<version>1.4</version>
</dependency>

排列实例：

    @Test    public void testName() throws Exception {        List<String> list = Arrays.asList("a", "b", "c");        for (List<String> tempList : Permutation.of(list, 2)) {            System.out.println(tempList);        }        System.out.println("从3个不同元素中取出2个元素，排列数="+Permutation.of(list, 2).getPermutationCount());    }

执行结果：

[a, b]
[b, a]
[a, c]
[c, a]
[b, c]
[c, b]
从3个不同元素中取出2个元素，排列数=6

业务实例：

  /**     * 排列不同sku，验证创建结果     * 业务约束：1.主商品已参加过附件促销不可继续创建；2.主品和附件库房属性必须一致     * @param venderId  商家id     * @param mainSkuId 主商品id     * @param attachSkuId 附件商品id     * @throws Exception     */    @Test(dataProvider = "skuInfo")    @Description(description = "主品和附件顺序不同时创建附件促销，验证创建结果")    public void testcreate_10(Long venderId,Long mainSkuId, Long attachSkuId) throws Exception {        deleteAttachPromotionBySkuId(venderId,mainSkuId);        PromoUtils.removePromotionBySkuId(GiftPromotionReadService.class, GiftPromotionWriteService.class, venderId, mainSkuId);        Logger.log("设置促销信息");        GiftPromotion giftPromotion = getGiftPromotion();        Logger.log("设置主品和附件");        List<PromotionSku> list = new ArrayList<PromotionSku>();        list.addAll(buildPromoSkuList(BindType.MAIN, mainSkuId, 1));        list.addAll(buildPromoSkuList(BindType.ATTACHMENT, attachSkuId, 1));        giftPromotion.setPromotionSkus(list);        Result<Long> create = this.invoke(attachPromotionWriteService, "create", Long.class, clientInfo, giftPromotion);        boolean testResult = false;        if (!create.isSuccess()) {            if (create.getCode().equals("ware.attachment.stock.not.match")) {                testResult = true;                System.out.println("库房属性不一致");            }else if (create.getCode().equals("attach.promo.already.exist")) {                testResult = true;                System.out.println("主品已经存在附件促销");            }            Assert.assertTrue(testResult);        }else            Assert.assertTrue(create.isSuccess());    }

构造参数排列：

    public static Object[][] buildBasicDataList() throws Exception {        HashMap<Long, List<Long>> map = new HashMap<Long, List<Long>>();        map.put(35881L, Arrays.asList(10000132915L, 10000132916L, 10000132917L));//        map.put(venderId, Arrays.asList(mainSkuId, attachSkuId1, attachSkuId2));        Set<Map.Entry<Long, List<Long>>> entrySet = map.entrySet();        List<Object[]> tempList = new ArrayList<Object[]>();        for (Map.Entry<Long, List<Long>> entry : entrySet) {            for (List<Long> list : Permutation.of(entry.getValue(), 2)) {                List<Long> arrayList = new ArrayList<Long>();                arrayList.add(entry.getKey());                arrayList.addAll(list);                System.out.println(arrayList);                tempList.add(arrayList.toArray());            }        }        Object[][] objects = new Object[tempList.size()][];        for (int i = 0; i < tempList.size(); i++) {            objects[i] = tempList.get(i);        }        System.out.println(objects.length);        return objects;    }

注入接口参数：

    @DataProvider(name = "skuInfo")    public static Object[][] skuInfo() throws Exception {        return buildBasicDataList();    }

测试执行结果：
