在我的项目中，我正在尝试使用（Cucumber + TestNG + Maven）构建框架，但在设计基类和与其他类中的pageobjects集成时，问题出现了.guntime.CucumberException：无法实例化类，
在我的结构中，我使用的基类包括调用浏览器实例的方法，拆除浏览器，然后访问accesssormethods来访问不同类的浏览器实例
然后，在我的另一个类中，我有我的pageobjects和构造函数来初始化pageobjects
第三，我有一个由stepdefintion类组成的类，它对应于特征文件，在步骤定义类中，我声明了baseclass和我的pageobjects类的实例，然后通过baseclass的accessor方法传递驱动程序但是尽管我的代码是不起作用请参考下面的代码和附件中的功能文件： -
基类代码： -
public class Basehelper {
protected WebDriver driver;
protected NgWebDriver ngdriver;
@Before
public void initializebrowser()
{
System.setProperty("webdriver.gecko.driver",System.getProperty("user.dir")+"\\Drivers\\geckodriver.exe");
driver=new FirefoxDriver();
ngdriver= new NgWebDriver((JavascriptExecutor)driver);
driver.manage().window().maximize();
driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
driver.get("https://rmi.com/");
ngdriver.waitForAngularRequestsToFinish();
driver.findElement(ByAngular.model("username")).sendKeys("rmidev");
driver.findElement(ByAngular.model("password")).sendKeys("rmidev");
driver.findElement(ByAngular.buttonText("Submit")).submit();
driver.manage().timeouts().implicitlyWait(10,TimeUnit.SECONDS);
}
@Before("@selectdistrict15")
public void changetodistrict15()
{
ngdriver.waitForAngularRequestsToFinish();
driver.findElement(By.id("mainMenu_changeDistrictMenu")).click();
ngdriver.waitForAngularRequestsToFinish();
((JavascriptExecutor)driver).executeScript("arguments[0].scrollIntoView(true);",driver.findElement(By.id("changeDistrictMenu_jmsRusselMetals")));
driver.findElement(By.id("changeDistrictMenu_jmsRusselMetals")).click();
ngdriver.waitForAngularRequestsToFinish();
driver.findElement(By.id("jmsRusselMetals_DistTo15-JmspBlytheville")).click();
driver.findElement(By.id("app_previous")).click();
ngdriver.waitForAngularRequestsToFinish();
}
@After
public void teardown()
{
driver.close();
}
public WebDriver getbaseclassdriver()
{
return driver;
}
public NgWebDriver getbaseclassngdriver()
{
return ngdriver;
}
步骤定义类
public class IM801CLPageDefintion {
Basehelper h=new Basehelper();
IM801CLPageObjects obj=new IM801CLPageObjects(h.getbaseclassdriver());
@When("^we navigate menu$")
public void we_navigate_menu() throws Exception {
obj.Inventorymenu.click();
h.getbaseclassngdriver().waitForAngularRequestsToFinish();
((JavascriptExecutor)h.getbaseclassdriver()).executeScript("arguments[0].scrollIntoView(true);",obj.InventoryExceptionMenu);
obj.InventoryExceptionMenu.click();
h.getbaseclassngdriver().waitForAngularRequestsToFinish();
obj.TaggedcostMenu.click();
}
@Then("^click on enter button$")
public void click_on_enter_button() {
h.getbaseclassngdriver().waitForAngularRequestsToFinish();
obj.Enterbutton.click();
}
@Then("^click on return to main menu$")
public void click_on_return_to_main_menu() {
h.getbaseclassngdriver().waitForAngularRequestsToFinish();
obj.returnbutton.click();
}
@When("^remove the district field value$")
public void remove_the_district_field_value() {
obj.DistrictField.clear();
}
}
亚军类： -
package runner;
import org.testng.annotations.Test;
import cucumber.api.CucumberOptions;
import cucumber.api.testng.AbstractTestNGCucumberTests;
@CucumberOptions(features={"src//test//resources//featurefiles"},glue= {"im801clsteps"},plugin={"html:target/cucumber-html-report",
"json:target/cucumber.json", "pretty:target/cucumber-pretty.txt"})
@Test
public class MainRunner extends AbstractTestNGCucumberTests
{
}
