Question

我正在尝试对以下内容进行单元测试

@app.route('/questionSearch', methods=['POST'])
def search():
    body = request.get_json()
    search_result = Question.query.filter(Question.question.ilike('%'+body['searchTerm']+'%')).all()
    total_questions = Question.query.all()
    formated_result = [result.format() for result in search_result]
    return jsonify({
      'success':True,
      'questions': formated_result,
      'totalQuestions': len(total_questions)
      #'currentCategory': categories
    })

我测试的方式是：

   def test_add_question(self):
        res =self.client().post('/questions',
        json= {"question": "new Test question?", "answer":"Test answer", "difficulty":1, "category":1 })
        data=json.loads(res.data)

        self.assertEqual(res.status_code, 200)
        self.assertEqual(data['success'],True)

它有效，但我如何避免向数据库添加一百万个问题，目前每次运行测试脚本时，它都会向测试数据库添加一个新问题。

我应该在拆卸中写一个删除命令吗？

您可以尝试使用 mock.patch 重写您的测试以模拟数据库（并完全避免接触数据库），如下所示：

    func buildRoundView(roundView: UIView, total : Int, current : Int){
    roundView.layer.cornerRadius = roundView.frame.size.width / 2
    roundView.backgroundColor = .clear
    let width :CGFloat = 10.0
    let reducer :CGFloat = 0.010
    let circlePath = UIBezierPath(arcCenter: CGPoint (x: roundView.frame.size.width / 2, y: roundView.frame.size.height / 2),
                                  radius: roundView.frame.size.width / 2,
                                  startAngle: CGFloat(-0.5 * Double.pi),
                                  endAngle: CGFloat(1.5 * Double.pi),
                                  clockwise: true)
    let multiplier = CGFloat((100.000 / Double(total)) * 0.0100)
    
    for i in 1...total {
        
        let circleShape = CAShapeLayer()
        circleShape.path = circlePath.cgPath
        if i <= current {
            circleShape.strokeColor = UIColor.systemRed.cgColor
        }
        else{
            circleShape.strokeColor = UIColor.lightGray.cgColor
        }
        
        circleShape.fillColor = UIColor.clear.cgColor
        circleShape.lineWidth = width
        circleShape.strokeStart = CGFloat(CGFloat(i - 1) * multiplier) + reducer
        circleShape.strokeEnd = CGFloat(CGFloat(i) * multiplier) - reducer
        roundView.layer.addSublayer(circleShape)
    }
}
