我试图在密钥驱动框架中使用JXL设置或写入执行测试用例的结果。此外，我能够编写或设置结果，但仅限于第一次迭代。在第二次迭代时，它显示空指针异常。我试过但不明白究竟是什么问题？
主要方法：
public class MainClass {
private static final String BROWSER_PATH = "D:\\FF18\\firefox.exe";
private static final String TEST_SUITE_PATH = "D:\\configuration\\GmailTestSuite.xls";
private static final String OBJECT_REPOSITORY_PATH = "D:\\configuration\\objectrepository.xls";
private static final String ADDRESS_TO_TEST = "https://www.gmail.com";
// other constants
private WebDriver driver;
private Properties properties;
/* private WebElement we; */
public MainClass() {
File file = new File(BROWSER_PATH);
FirefoxBinary fb = new FirefoxBinary(file);
driver = new FirefoxDriver(fb, new FirefoxProfile());
driver.get(ADDRESS_TO_TEST);
}
public static void main(String[] args) throws Exception {
MainClass main = new MainClass();
main.handleTestSuite();
}
private void handleTestSuite() throws Exception {
ReadPropertyFile readConfigFile = new ReadPropertyFile();
properties = readConfigFile.loadPropertiess();
ExcelHandler testSuite = new ExcelHandler(TEST_SUITE_PATH, "Suite");
testSuite.columnData();
int rowCount = testSuite.rowCount();
System.out.println("Total Rows=" + rowCount);
for (int i = 1; i < rowCount; i++) {
String executable = testSuite.readCell(
testSuite.getCell("Executable"), i);
System.out.println("Executable=" + executable);
if (executable.equalsIgnoreCase("y")) {
// exe. the process
String scenarioName = testSuite.readCell(
testSuite.getCell("TestScenario"), i);
System.out.println("Scenario Name=" + scenarioName);
handleScenario(scenarioName);
}
}
