根因分析

测试尝试访问 Flask 的 current_app 或其他上下文局部对象，但没有活动的应用程序上下文。这通常发生在测试使用 Flask 全局变量的代码时，不在请求或应用上下文中。

English

A test tries to access Flask's current_app or other context-local objects without an active application context. This often occurs when testing code that uses Flask globals outside a request or app context.

    def test_something(app):
    with app.app_context():
        # code that uses current_app
        ...
  2. 95% 成功率 
    def test_something(app):
    with app.app_context():
        ...
  3. 90% 成功率 
    def test_request(client):
    response = client.get('/')
    ...

无效尝试

常见但无效的做法:

  1. 90% 失败

    This enables testing mode but does not create an application context.

  2. 85% 失败

    The context must be pushed (with app.test_request_context():) to be active.

  3. 95% 失败

    This still requires an active context; it just returns the object if one exists.
