selenium2java利用mysql實現重複購買用例

本人在學習使用selenium2java的過程中，遇到過需要測試方案購買的問題，每次買完之後都得手動清除一下數據，重新測試購買流程。在寫自動化用例的時候用到了數據庫相關方法，分享一下，供參考。

//購買志願方案（使用兌換卡）
	public static void buyWishProjectByCoupon(WebDriver driver) throws ClassNotFoundException, SQLException, IOException, InterruptedException {
		MySql.UpdateOrderStutas(user_id);//使用戶當前已購買訂單過期
		findElementByIdAndClick(driver, "btnIndexPay");//點擊購買
		findElementByXpathAndClick(driver, ".//*[@id='payment_channel']/li[1]");//點擊兌換卡購買
		findElementByIdAndClick(driver, "btnOrderCreatePay");//點擊立即支付
		/*如果用戶之前購買過，則在第一行設置爲過期
		 * 如果用戶之前生成過訂單，會提示雷同，跳轉訂單頁面，繼續選擇兌換卡支付
		 * 如果用戶沒有購買過或者訂單全部過期，直接使用兌換卡支付
		 */
		if (exists(driver, By.className("confirm"))) {
			sleep(0);
			findElementByClassNameAndClick(driver, "confirm");
			findElementByTextAndClick(driver, "立即支付");
			findElementByIdAndClick(driver, "btnOrderCreatePay");//點擊立即支付
			payByCoupon(driver);
			}else{
				payByCoupon(driver);
				}
		driver.get("http://172.21.134.15:5555/purchase/order/list");//跳轉我的訂單頁面
		refresh(driver);//強制刷新
		String status = getTextByClassName(driver, "pull-right");//獲取最新訂單狀態
		assertTrue("購買課程失敗！", status.equals("已付款"));
	}

下面是使用兌換卡的方法：

	//兌換卡支付
	public static void payByCoupon(WebDriver driver) throws ClassNotFoundException, SQLException {
		String coupon_id = MySql.getCouponIdAndPassword();//獲取帳號
		findElementByIdAndClearSendkeys(driver, "input-coupon_number", coupon_id);//輸入帳號
		findElementByIdAndClearSendkeys(driver, "input-coupon_password", "123456");//輸入密碼
		findElementByXpathAndClick(driver, ".//*[@id='modal-pay_card']/div/div/div[2]/div/div/div[2]/div/div[4]/div/button");//點擊支付
	}

下面是修改用戶訂單狀態的方法：

//修改用戶訂單狀態
	public static void UpdateOrderStutas(int id) throws ClassNotFoundException, SQLException, IOException {
		// 加載驅動程序
		Class.forName(driver);
		// 連接數據庫
		Connection connection = DriverManager.getConnection(url, user, password);
		if(!connection.isClosed()){
			Statement statement = connection.createStatement();
			//1是代付款，2是已付款，5是已過期
			String sql = "UPDATE op_orders SET order_status = 5 where user_id = "+id+" and order_status= 2";
			statement.executeUpdate(sql);
			connection.close();
            }else {
            	output("failed connecting to the Database!");
            	}
		}

下面是獲取尚未使用的兌換卡的方法：

//查找尚未使用的兌換卡帳號和密碼
	public static String getCouponIdAndPassword() throws SQLException, ClassNotFoundException {
		String coupon_id = null;
		Class.forName(driver);
		Connection connection = DriverManager.getConnection(url, user, password);
		if (!connection.isClosed()) {
			Statement statement = connection.createStatement();
			String sql = "SELECT * FROM op_coupon LEFT JOIN op_coupon_used on op_coupon.coupon_id = op_coupon_used.coupon_id WHERE op_coupon_used.order_no is null limit 1";
			ResultSet result = statement.executeQuery(sql);
//			output("帳號"+"\t"+"密碼");
			while(result.next()){
				coupon_id = result.getString("serial_no");
//				output(result.getString("serial_no")+"\t"+result.getString("serial_password"));
			}
			result.close();
			connection.close();
		}
		return coupon_id;
		
	}
