我有一个简单的Extjs-5应用程序，我正在编写测试。 应用程序在我的本地服务器上运行良好。我有一个搜索字段，我可以通过Selenium和JUnit找到并测试，但是当我尝试点击我的应用程序中的按钮时，我得到以下异常
org.openqa.selenium.NoSuchElementException: no such element

我的测试课程是：
public class MyBaseTest extends BaseSeleniumTest {
private MyModel model;
public MyBaseTest() {
model = new MyModel(this);
}
@Test
public void testResetForm(){
driver.get("http://localhost:1841/");
this.waitToBeClickable(MyModel.SEARCH_XPATH);
WebElement searchInput = model.findSearchInput();
WebElement addButton = model.findAddButton();
searchInput.sendKeys("Yawar");
assertEquals("Yawar", searchInput.getAttribute("value"));
addButton.click(); // Test Breaking at this line with the above mentioned exception
}
}
这是我的模特课：
public class MyModel extends BaseModel {
public static final String SEARCH_XPATH = XPathUtils.findInputByName("searchField");
public static final String ADD_XPATH = XPathUtils.findButtonByText("Add");
public MyModel(BaseSeleniumTest test) {
super(test);
}
public WebElement findSearchInput(){
return this.find(SEARCH_XPATH);
}
public WebElement findAddButton(){
System.out.println(ADD_XPATH);
return find(ADD_XPATH);
}
}
我在堆栈溢出方面发现了类似的问题，例如org.openqa.selenium.NoSuchElementException: no such element 但他们没有接受答案，他们建议增加我做的等待，但在任何一种情况下都会发生同样的异常。 请帮助。
