Python pytest失败：can'；找不到请求的URL

python flask

Python pytest失败：can'；找不到请求的URL,python,flask,pytest,Python,Flask,Pytest,我有一个Flask应用程序： myapp.py： def create_app(): app = Flask(__name__) return app app = create_app() session = session_factory() def connect_db(): engine = get_engine() return engine.connect() @app.route("/") def hello(): return "He

我有一个

Flask

应用程序：

myapp.py：

def create_app():
    app = Flask(__name__)
    return app

app = create_app()
session = session_factory()


def connect_db():
    engine = get_engine()
    return engine.connect()

@app.route("/")
def hello():
    return "Hello everyone"

我想编写一些pytest测试，因此创建了两个文件：

conftest.py:

import pytest
from app.myapp import create_app

@pytest.fixture
def app():
    app = create_app()
    return app

@pytest.fixture
def client(app):
    return app.test_client()

@pytest.fixture
def runner(app):
    return app.test_cli_runner()

测试端点.py

import pytest
from flask import *

def test_hello(client):
    response = client.get("/")
    assert response.data == b'Hello everyone'

当我运行pytest时，会出现以下错误：

>       assert response.data == b'Hello everyone'
E       assert '<!DOCTYPE HT... again.</p>\n' == 'Hello everyone'
E         + Hello everyone
E         - <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
E         - <title>404 Not Found</title>
E         - <h1>Not Found</h1>
E         - <p>The requested URL was not found on the server.  If you entered the URL manually please check your spelling and try again.</p>

>assert response.data==b'Hello everyone'
E断言“您没有向从夹具中的create_app（）
获得的app
添加任何路由
如果你考虑你的代码
def create_app():
    app = Flask(__name__)
    return app

app = create_app()

# ...

@app.route("/")
def hello():
    return "Hello everyone"

，该hello
路线仅添加到该全局app
实例中，而不是从夹具中获取的实例
烧瓶教程，其中。你可能也想这么做；像这样的
bp = Blueprint('greetings', __name__)

@bp.route("/")
def hello():
    return "Hello everyone"

def create_app():
    app = Flask(__name__)
    app.register_blueprint(bp)
    return app

所以，事实上，我不打算直接调用应用程序端点，但我需要创建“假”端点并对其进行测试？不，不。您只需要使用蓝图进行路由映射，以便在生产应用程序和测试实例之间重用它们。
