这是我在SO的第一篇文章;我是新手Selenium用户，具有Java初学者技能。
为您提供我们工作的背景;我们正在使用页面对象模型。我们所有的测试都使用一个 DataProvider 方法，该方法从＆＃34; .xlsx＆＃34;中提取数据。基于调用/使用DataProvider的测试用例名称的文件。
我们不确定是否已按照应有的方式宣布我们的 ThreadLocal 。而且，我们不确定 getDriver（）方法的声明是否正确。另一个问题是我们不确定是否应该使用 ＆＃34; @ BeforeTest＆＃34; /＆＃34; @ AfterTest＆＃34; 或 < em>＆＃34; @ BeforeClass＆＃34; /＆＃34; @ AfterClass＆＃34; 在我们的设置和 tearDown 方法上。
遇到以下问题：
以下是我们的CONFIGTESTBASE类：
public class ConfigTestBase {
private static ThreadLocal<RemoteWebDriver> threadedDriver = null;
private static XSSFSheet ExcelWSheet;
private static XSSFWorkbook ExcelWBook;
private static XSSFCell Cell;
private static XSSFRow Row;
private static final String Path_TestData = GlobalConstants.testDataFilePath;
private static final String File_TestData = GlobalConstants.testDataFileName;
@Parameters({"objectMapperFile"})
@BeforeSuite
public void setupSuite(String objectMapperFile) throws Exception {
GlobalConstants.objectMapperDefPath = new File(objectMapperFile).getAbsolutePath();
new Common().OverrideSSLHandshakeException();
}
@Parameters({"browserName"})
@BeforeClass
public void setup(String browserName) throws Exception {
threadedDriver = new ThreadLocal<>();
DesiredCapabilities capabilities = new DesiredCapabilities();
if (browserName.toLowerCase().contains("firefox")) {

capabilities.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
capabilities.setBrowserName("firefox");
capabilities.setPlatform(Platform.WINDOWS);
}
if (browserName.toLowerCase().contains("ie")) {
System.setProperty("webdriver.ie.driver","C:\\selenium\\IEDriverServer.exe");

options.setUseCleanSession(true);
capabilities = DesiredCapabilities.safari();
capabilities.setCapability(SafariOptions.CAPABILITY, options);

capabilities.setPlatform(Platform.WINDOWS);
}
threadedDriver.set(new RemoteWebDriver(new URL(GlobalConstants.GRIDHUB), capabilities));
}
protected static RemoteWebDriver getDriver(){
RemoteWebDriver driver = null;
try {
driver = threadedDriver.get();
} catch (Exception e) {
e.printStackTrace();
}
return driver;
}
@AfterClass
public void tearDown() throws Exception {
getDriver().quit();
}

throw (e);
}
}
//This method is to read the test data from the Excel cell, in this we are passing parameters as Row num and Col num
@SuppressWarnings("static-access")
public String getCellData(int RowNum, int ColNum) throws Exception{
try{

FileOutputStream fileOut = new FileOutputStream(Path_TestData + File_TestData);
ExcelWBook.write(fileOut);
fileOut.flush();
fileOut.close();
} catch (Exception e) {
throw (e);
}
}
@DataProvider(name="getDataFromFile")
public Object[][] getDataFromFile(Method testMethod, ITestContext context) throws Exception {
String[][] tabArray;
int intCounter;
int intRowCount = 0;
int intRowCounter = 0;
int intColCount = 0;
int intColCounter;

String testName = testMethod.getName();
String banner = context.getCurrentXmlTest().getParameter("banner");
setExcelFile(Path_TestData + File_TestData, banner);
//get number of data to be returned
for(intCounter=0;intCounter<ExcelWSheet.getLastRowNum()+1;intCounter++){
if(getCellData(intCounter, 1).equals(testName)) {
if (intColCount == 0) {
intColCount = ExcelWSheet.getRow(intCounter).getLastCellNum() - 2;
}
intRowCount++;
}
}
if(intRowCount == 0){
System.out.println("\n*** Data for '" + testName + "' was not found.");
throw new AssertionError("Data for '" + testName + "' was not found.");
}
for(intCounter=0;intCounter<ExcelWSheet.getLastRowNum()+1;intCounter++){
if(getCellData(intCounter, 1).equals(testName)) {
for(intColCounter=2;intColCounter<intColCount+2;intColCounter++) {

tabArray[intRowCounter-1][intColDataCounter] = getCellData(intCounter,intColCounter);
intColDataCounter++;
}
}
}
}
return tabArray;
}
}
以下是我们拥有的示例测试类;扩展了CONFIGTESTBASE类......每个测试一个类：
public class Google6 extends ConfigTestBase {
private Generic generic = null;
private HomePage homePage = null;
@BeforeMethod
public void MethodInit(ITestResult result) throws Exception {
generic = new Generic(getDriver());
homePage = new HomePage(getDriver());
}
@Test(dataProvider="getDataFromFile")
public void Google6(String execute, String url, String searchString) throws Exception {
if(execute.toUpperCase().equals("YES")) {
//navigate to application page
generic.navigateToURL(url);
//search
homePage.search(searchString);
} else {
generic.log("Execute variable <> 'YES'. Skipping execution...");
throw new SkipException("Execute variable <> 'YES'. Skipping execution...");
}
}
}
这是我们的套件文件; ＆＃39;横幅＆＃39;参数用于在＆＃34; .xlsx＆＃34;上查找特定表格。文件：的

关于我们如何使其发挥作用的任何建议？
答案 0 :(得分：2)
1）您正在为每个测试类实例化一个新的ThreadLocal，因为它在BeforeClass注释中。您应该同时声明并实例化ThreadLocal：
private static ThreadLocal<RemoteWebDriver> threadedDriver = new ThreadLocal<>();
2）Excel解析逻辑是疯了。至少，你需要将它分成它自己的类。如果可能的话，使用.csv文件而不是.xlsx文件，并使用类似opencsv的东西来解析文件;它将震撼你的世界。解析后，您可以将其转换为TestNG的DataProvider所期望的内容。像这样：
public class CSVDataReader {
private static final char DELIMITER = ',';
private static final char QUOTE_CHAR = '\"';
private static final char ESCAPE_CHAR = '\\';
private static List<String[]> read(String filePath, boolean hasHeader) throws IOException {
CSVReader reader;
if (hasHeader) {
// If file has a header, skip the header (line 1)
reader = new CSVReader(new FileReader(filePath), DELIMITER, QUOTE_CHAR, ESCAPE_CHAR, 1);
} else {
reader = new CSVReader(new FileReader(filePath), DELIMITER, QUOTE_CHAR, ESCAPE_CHAR);
}
List<String[]> rows = reader.readAll();
reader.close();
return rows;
}
public static String [][] readCSVFileToString2DArray(String filePath, boolean hasHeader) throws IOException {
List<String[]> rows = read(filePath, hasHeader);
// Store all rows/columns in a two-dimensional String array, then return it
String [][] csvData = new String[rows.size()][];
int r = 0;
for (String[] row : rows) {
csvData[r++] = row;
}
return csvData;
}
}

一次一件事......我相信你已被某人移交过这段代码。请先查看如何初始化threadlocal here
尝试使用一小段代码逐个缩小您的问题，以了解根本原因
答案 2 :(得分：0)
一些建议。
尝试分离您在逻辑上分离任务的内容。例如。初始化驱动程序和数据提供程序是两个单独的任务。您可以在单独的类中创建数据提供者，并在任何测试中引用它，例如。 “By default, the data provider will be looked for in the current test class or one of its base classes. If you want to put your data provider in a different class, it needs to be a static method and you specify the class where it can be found in the dataProviderClass attribute:”
您的驱动程序实例化可以是一个单独的类，因为它都是静态的。 threadlocal的实例化应该在声明点。值的设置应该在线程中。因此，将新的ThreadLocal移动到您的声明中。
