Unit testing 404使用pytest测试烧瓶应用时未找到
如果我手动运行这个简单的web服务,它就会工作,但是在我的单元测试中,我会得到一个404NotFound页面作为我的响应,这会妨碍我正确地测试应用程序 正常行为: 文件夹结构:Unit testing 404使用pytest测试烧瓶应用时未找到,unit-testing,testing,flask,automated-tests,http-status-code-404,Unit Testing,Testing,Flask,Automated Tests,Http Status Code 404,如果我手动运行这个简单的web服务,它就会工作,但是在我的单元测试中,我会得到一个404NotFound页面作为我的响应,这会妨碍我正确地测试应用程序 正常行为: 文件夹结构: /SRC --web_application.py /UNIT_TESTS --test_wab_application.py web_application.py from flask import Flask, request, jsonify, send_from_directory from python

测试结果(仅限最相关部分):
到目前为止,我已经测试了test-web_application.py
中的client.get()
方法的各种可选路由路径,包括像“/SRC/greetings?name=Rick Sanchez”或“../SRC/greetings?name=Rick Sanchez”这样的组合,但都没有不同的效果
您是否知道我可能做错了什么,或者如何从单元测试中访问web服务的功能?我认为问题在于您正在创建两个
Flask
实例。其中一个名为application
,您可以将其添加到hello
路由,第二个名为create\u app
功能。您需要使用应用程序
实例(您将hello
路由添加到的实例)创建一个测试客户机
是否可以导入应用程序
,然后使用应用程序获取客户端
。test_client()
样品溶液:
导入pytest
从web_应用程序导入应用程序
@pytest.fixture
def client():
使用application.test_client()作为客户端:
收益客户
类TestSomething:
def测试_此(自身、客户端):
res=client.get('/greetings?name=Rick Sanchez')
assert res.status_code==200
