Pytest失败退出代码1，(github操作)

Question

我有一个github存储库，它有一个文件Test_app.py。我正在github操作中对文件运行pytest，并不断收到错误消息：E botocore.exceptions.NoRegionError: You must specify a region.

然后，我将文件中的区域指定为：dynamodb = boto3.resource('dynamodb', region_name= 'eu-west-2')。当我执行pytest时，会得到以下错误：

platform win32 -- Python 3.8.6, pytest-6.2.0, py-1.10.0, pluggy-0.13.1
rootdir: D:acloudresumechallenge-BackEndcloudresumechallenge-BackEnd
collected 0 items
============================ no tests ran in 0.31s ============================
Error: Process completed with exit code 1. 

这是我的lambda代码：

import boto3
import json
dynamodb = boto3.resource('dynamodb', region_name= 'eu-west-2')
table= dynamodb.Table('zacresumetable2')
def lambda_handler(event, context):
response= table.update_item(
Key= {'URL': 'zacresume.com'},
UpdateExpression= "SET visits = visits + :increase",
ExpressionAttributeValues= {':increase': 1},
ReturnValues= "UPDATED_NEW"
)
return {'statusCode': 200,
'body': json.dumps('visitsUpdated'),
'headers': {'Content-Type': 'application/json'}}
print("UPDATING ITEM")
print("response") 

这就是pytest的工作流程：

Answer 1

首先，您应该确保您的测试用例从给定数据中的test_开始——在我看来，您没有正确设置测试。例如，这是应用程序的正确结构。

• MyApp/
  • run.py
  • 测试/
    • test_function_1.py

在test_function_1.py内部，您应该具有：

# Just for the sake of the example
def test_func_case_1():
assert True
def test_func_case_2():
assert 1 == 1

请检查此代码并告诉我它是否对您有所帮助。
