本人在學習使用selenium2java的過程中，遇到了測試支付寶和微信購買課程的用例，寫起來略微複雜了一些，因為考慮到重複測試，得先修改使用者訂單狀態，還得考慮使用者已經買過、下單未付款、第一次購買等情況，中間用到了if-else if -else的判斷語法，還得切換視窗。下面分享出來，供大家參考。

//購買班課
	public static void BuyCourseWithoutPay(WebDriver driver) throws InterruptedException, ClassNotFoundException, SQLException {
		MySql.alterUserOrdersStatus();//修改使用者訂單狀態
		clickCourseMore(driver);
		selectGradeAndSubject(driver, "初一", "數學");
		findElementByXpathAndClick(driver, "html/body/div[2]/div[3]/div[1]/ul/li[1]");//選擇課程
		clickApply(driver);
		/*如果已經購買過尚未支付，會跳轉到訂單頁面，點選支付，選擇支付寶和微信，驗證跳轉頁面title和彈框
		 * 注意切換視窗，支付寶會出現先視窗
		 * 如果沒有購買過或者已經過期訂單，會跳轉到提交訂單頁面
		 */
		if (exists(driver, By.id("commitOrder"))) {//如果發現立即支付按鈕，則去支付頁面
			clickCommitOrder(driver);//點選訂單頁面立即支付
			findElementByClassNameAndClick(driver, "alipay");//選擇支付寶支付
			String homehandle = driver.getWindowHandle();//獲取頁面handle
			findElementByIdAndClick(driver, "payment_btn");//點選立即支付
			Set<String> handles = driver.getWindowHandles();//獲取當前handles
			for(String handle : handles){
				if (handle.equals(homehandle) == false) {
					driver.switchTo().window(handle);//切換到支付寶頁面
					assertEquals("跳轉支付寶失敗！", "支付寶 - 網上支付 安全快速！", driver.getTitle());
					driver.close();//關閉支付寶視窗
					}
				}
			for(String handle : handles){
				if (handle.equals(homehandle)) {
					driver.switchTo().window(handle);//切換到原來的視窗
					findElementByClassNameAndClick(driver, "layui-layer-setwin");//關閉支付支付彈框
					sleep(0);
					findElementByClassNameAndClick(driver, "wxpay");//點選微信支付
					findElementByIdAndClick(driver, "payment_btn");//點選立即支付
					assertEquals("微信支付彈框二維碼失敗！", "微信掃描二維碼以完成支付", getTextByXpath(driver, ".//*[@id='LAY_layuipro1']/div/p"));
					}
				}
			}else if (exists(driver, By.className("address"))) {//如果發現有收貨地址，先刪除
				moveToElementByClassName(driver, "address");//滑鼠移動到收貨地址上
				clickDeleteAdress(driver);
				sleep(0);
				clickSure(driver);
				sleep(0);
				}else {//新增收貨地址
					AddAddress(driver);
					sleep(0);
					clickCommitOrder(driver);
					findElementByClassNameAndClick(driver, "alipay");//選擇支付寶支付
					String homehandle = driver.getWindowHandle();
					findElementByIdAndClick(driver, "payment_btn");//點選立即支付						
					Set<String> handles = driver.getWindowHandles();
					for(String handle : handles){
						if (handle.equals(homehandle) == false) {
							driver.switchTo().window(handle);//切換到支付寶頁面
							assertEquals("跳轉支付寶失敗！", "支付寶 - 網上支付 安全快速！", driver.getTitle());
							driver.close();
							}
						if (handle.equals(handle)) {
							driver.switchTo().window(handle);
							findElementByClassNameAndClick(driver, "layui-layer-setwin");//關閉支付支付彈框
							findElementByClassNameAndClick(driver, "wxpay");//點選微信支付

							assertEquals("微信支付彈框二維碼失敗！", "微信掃描二維碼以完成支付", getTextByXpath(driver, ".//*[@id='LAY_layuipro1']/div/p"));
							}
						}
					}

			statement.executeUpdate(sql);
