解決unittest中斷言失敗，後續的斷言都不執行的問題
阿新 • • 發佈：2021-01-10
在unittest測試用例中，在含有多個斷言時，一個斷言失敗後，測試用例會結束執行，無法知道其他斷言是否成功。unittest不同與pytest，在pytest中，
可以使用pytest.assume(表示式)，檢查點失敗繼續執行，所以為了解決unittest的這個弊端，本文解決方式： 1）把多個斷言合成一個斷言，判斷多個斷言的綜合結果是True還是False 2）判斷每個斷言結果，失敗則彙總，在最終斷言中輸出 之前多斷言程式碼：1 def checkCMSTab(self, tabLabelInfo, tabName): 2 '''驗證CMS源tab下有無空資料3 驗證tab下有無售罄、下架商品 4 驗證tab下圖片坑位是否配置跳轉連結''' 5 unsaleWareInfos = '' 6 offlineWareInfos = '' 7 unsaleWareInfoList = tabLabelInfo[1] 8 offlineWareInfoList = tabLabelInfo[2] 9 actsInfoList = tabLabelInfo[1] 10 pictureEroorInfos = '' 11 pictureEroorList = []12 13 if len(unsaleWareInfoList) > 0: 14 for ware in unsaleWareInfoList: 15 unsaleWareInfos += '\n導航2Ntab下{tab}-tab{sku}—{wareName}商品已售罄，該商品資料異常，應該被過濾'.format( 16 tab=ware[4],17 sku=ware[0], 18 wareName=ware[1]) 19 # 驗證tab下商品售罄、不可售 20 if len(offlineWareInfoList) > 0: 21 for ware in offlineWareInfoList: 22 offlineWareInfos += '\n導航2Ntab下{tab}-tab{sku}—{wareName}商品已售罄，該商品資料異常，應該被過濾'.format( 23 tab=ware[4], 24 sku=ware[0], 25 wareName=ware[1]) 26 for picture in actsInfoList: 27 if picture[1] == '' or picture[1] is None: 28 pictureEroorList.append(picture) 29 pictureEroorInfos += '\n{}坑位，無跳轉連結' 30 31 32 # 驗證tab下資料空 33 if len(tabLabelInfo[0][0]) + len(tabLabelInfo[1]) == 0: 34 self.assertNotEqual(len(tabLabelInfo[0][0]) + len(tabLabelInfo[1]), 0, 35 '導航2N樓層的{}tab下資料異常：tab資料為空'.format(tabName)) 36 if len(tabLabelInfo[0][0]) == 0: 37 self.assertNotEqual(len(tabLabelInfo[0][0]), 0, 38 '導航2N樓層的{}tab下資料異常：無商品資料'.format(tabName)) 39 40 self.assertLessEqual(len(unsaleWareInfoList), 0, '{tabName}tab下存在已售罄商品,具體資訊為{unsaleWareInfos}'.format( 41 tabName=tabName, 42 unsaleWareInfos=unsaleWareInfos)) 43 self.assertLessEqual(len(offlineWareInfoList), 0, '{tabName}tab下存在已下架商品,具體資訊為{offlineWareInfoList}'.format( 44 tabName=tabName, 45 offlineWareInfoList=offlineWareInfoList)) 46 # 驗證tab下圖片坑位是否無跳轉連結 47 self.assertEqual(len(pictureEroorList), 0, "{tabName}下圖片坑位無跳轉連結，具體資訊為{pictureEroorInfos}".format(tabName=tabName, 48 pictureEroorInfos=pictureEroorInfos))
優化後代碼如下：
def checkCMSTab(self, tabLabelInfo, tabName):
'''驗證CMS源tab下有無空資料
驗證tab下有無售罄、下架商品
驗證tab下圖片坑位是否配置跳轉連結'''
unsaleWareInfos = ''
offlineWareInfos = ''
unsaleWareInfoList = tabLabelInfo[1]
offlineWareInfoList = tabLabelInfo[2]
actsInfoList = tabLabelInfo[1]
pictureEroorInfos = ''
pictureEroorList = []
if len(unsaleWareInfoList) > 0:
for ware in unsaleWareInfoList:
unsaleWareInfos += '\n導航2Ntab下{tab}-tab{sku}—{wareName}商品已售罄，該商品資料異常，應該被過濾'.format(
tab=ware[4],
sku=ware[0],
wareName=ware[1])
# 驗證tab下商品售罄、不可售
if len(offlineWareInfoList) > 0:
for ware in offlineWareInfoList:
offlineWareInfos += '\n導航2Ntab下{tab}-tab{sku}—{wareName}商品已售罄，該商品資料異常，應該被過濾'.format(
tab=ware[4],
sku=ware[0],
wareName=ware[1])
for picture in actsInfoList:
if picture[1] == '' or picture[1] is None:
pictureEroorList.append(picture)
pictureEroorInfos += '\n{}坑位，無跳轉連結'
# 解決unittest中斷言失敗，後續的斷言都不執行的問題

res = res and (len(unsaleWareInfoList) == 0) # tab下是否存在已售罄
res = res and (len(offlineWareInfoList) == 0) # tab下是否存在已下架
res = res and (len(pictureEroorList) == 0) # 驗證tab下圖片坑位是否無跳轉連結
if len(tabLabelInfo[0][0]) + len(tabLabelInfo[1]) == 0:
msg.append('導航2N樓層的{}tab下資料異常：tab資料為空'.format(tabName))
if len(tabLabelInfo[0][0]) == 0:
msg.append('導航2N樓層的{}tab下資料異常：無商品資料'.format(tabName))
if len(unsaleWareInfoList) == 0:
msg.append('{tabName}tab下存在已售罄商品,具體資訊為{unsaleWareInfos}'.format(tabName=tabName,

self.assertEqual(res, "\n".join(msg))
