自動化測試模型可以看作自動化測試框架與工具設計的思想。隨著自動化測試技術的發展，演化為以下幾種模型：

• 線性測試
• 模塊化驅動側式
• 數據驅動測試
• 關鍵字驅動測試

數據驅動測試

前一篇所講的模塊化驅動測試能夠很好的解決腳本重復的問題，但是在針對同一個功能進行不同數據的測試，從而檢測測試結果的變化時仍然需要重復地編寫測試腳本。于是，數據驅動測試的概念就為解決這類問題而被提出。
我們可以通過讀取定義的數組、字典，或者是外部文件（excel、csv、txt、xml等），都可以看作是數據驅動，從而實現數據與腳本的分離，進一步增強腳本的復用性。

讀取txt文件

Java

(ノへ￣、)這段代碼存在一個問題，txt文件中有四組數據，但運行時只執行了三組數據（運行時忽略了一條密碼為空的數據）。

data.javapackage PublicMethods;import java.io.*; import java.util.*;public class data {//讀取txt文件public static Map txtData(String fileName) throws IOException {Map<String, String> map = new HashMap<String , String>(); //存放多個鍵值對String[] arryTemp = null;String username = null;String password = null;String s = null;File file = new File(fileName);FileReader fr = new FileReader(file);BufferedReader br = new BufferedReader(fr);while((s = br.readLine()) != null){arryTemp = s.split(","); //將一行數據存入數組username = arryTemp[0]; //獲取賬戶password = arryTemp[1]; //獲取密碼map.put(username, password); //存儲一組賬號密碼 }return map;} } share.javapackage PublicMethods;import org.openqa.selenium.By; import org.openqa.selenium.NoAlertPresentException; import org.openqa.selenium.WebDriver; import java.util.Map; import java.util.Set; import org.openqa.selenium.firefox.FirefoxDriver;public class share {private static WebDriver driver;public static WebDriver OpenDriver(String url){driver = new FirefoxDriver();driver.get(url);return driver;}public static void UserLogin(WebDriver driver, Map map) throws InterruptedException {Set<String> keyset = map.keySet(); //獲取Map的值for(String count : keyset) {Thread.sleep(2000);driver.findElement(By.xpath("//*[@id='username']")).sendKeys(count);System.out.println(count);driver.findElement(By.xpath("//*[@id='password']")).sendKeys(map.get(count).toString());Thread.sleep(2000);driver.findElement(By.xpath("//*[@id='login_button']")).click();Thread.sleep(2000);try{driver.switchTo().alert().accept();Thread.sleep(2000);driver.findElement(By.xpath("//*[@id='username']")).clear();driver.findElement(By.xpath("//*[@id='password']")).clear();}catch(NoAlertPresentException NofindAlert){UserLogout(driver);} }}public static void UserLogout(WebDriver driver) throws InterruptedException{driver.findElement(By.xpath("//*[@id='logout_button']")).click();Thread.sleep(2000);} } LoginTest.javapackage Test;import java.io.IOException; import java.util.*; import PublicMethods.*;import org.openqa.selenium.WebDriver;public class LoginTest {public static void main(String[] args) throws InterruptedException, IOException {// TODO Auto-generated method stubWebDriver driver = PublicMethods.share.OpenDriver("file:///D:/%E7%99%BB%E5%BD%95.html");String filename = "D:\\app_tool\\eclipse-workspace\\AutoTest\\TestData\\user_info.txt";Map map = txtData(filename);UserLogin(driver, map);driver.quit();} }

Python

讀取excel文件

Excel文件數據必須時文本格式

Java

進入http://poi.apache.org/download.html下載POI的Jar包
問題一：

解決方法：
進入http://mvnrepository.com/artifact/org.apache.xmlbeans/xmlbeans/2.6.0，下載jar包

問題二：

解決方法：
進入http://mvnrepository.com/artifact/org.apache.commons/commons-collections4/4.1，下載jar包

問題三：
在遇到Excel單元值為空時sheet.getRow(i).getCell(j).getStringCellValue()會報錯
解決方法：
在Excel中把空值改為空格，然后在代碼中獲取該值后去空格。

淺談關鍵字驅動測試

???????在數據驅動的基礎上，我們把“數據”轉化為“關鍵字”后，通過關鍵字的改變從而引起測試結果的變化。
???????為何我要在這里說明是“淺談”呢？在關鍵字驅動測試中，我們可以將測試的對象、滿足條件、傳輸值、斷言等，甚至是所需要讀取的外部文件以及外部類庫，所有的相關條件存儲在文件中（典型的關鍵字驅動工具：UFT）。我們可以將關鍵字以“填表格”形式寫入文件中，從而降低腳本的編寫難度。
???????正因如此，采用關鍵字驅動測試來編寫同樣的腳本需要較高的學習成本。同樣，這樣的框架越到后期越難維護，可靠性也會變差。所以，暫時不深入研究關鍵字驅動測試。
