（烧瓶）伪造request.environ ['REMOTE_USER']进行测试

从Flask应用程序单元测试的设置（模拟）请求标头中找出我自己问题的答案。有一个environ_base你可以通过请求环境变量为参数。它记录在werkzeug.test.EnvironBuilder中。

    def test_insert_cash_flow_through_post(self):
    """Test that you can insert a cash flow through post."""
    assert not CashFlow.query.first()
    self.client.post("/index?account=main",
                     environ_base={'REMOTE_USER': 'foo'},
                     data=dict(settlement_date='01/01/2016',
                               transaction_type='Other',
                               certainty='Certain',
                               transaction_amount=1))
    assert CashFlow.query.first().user == 'foo'
