url_for() properly handles that for you. For example, here we use the test_request_context() method to try out url_for(). test_request_context() tells Flask to behave as though it’s handling a request route('/user/') def profile(username): return '{}\'s profile'.format(escape(username)) with app.test_request_context(): print(url_for('index')) print(url_for('login')) print(url_for('login', next='/')) The easiest solution for unit testing is to use the test_request_context() context manager. In combination with the with statement it will bind a test request so that you can interact with it. Here is an

@app.route('/user/') def user_page(name): return 'User: %s' % name @app.route('/test') def test_url_for(): # 下面是一些调用示例： print(url_for('hello')) # 输出：/ # 注意下面两个调用是如何生成包含 URL 输出：/user/peter print(url_for('test_url_for')) # 输出：/test # 下面这个调用传入了多余的关键字参数，它们会被作为查询字符串附加到 URL 后面。 print(url_for('test_url_for', num=2)) # 输出：/test?num=2 return 'Test page' 实验过程中编写的代码可以删掉 tearDown(self): # 测试固件 pass def test_sayhello(self): # 第 1 个测试 rv = sayhello() self.assertEqual(rv, 'Hello!') def test_sayhello_to_somebody(self) # 第 2 个测试
