我似乎收到了一个pico容器异常：org.picocontainer.injectors.AbstractInjector $ UnsatisfiableDependenciesException。
我的代码如下：
代表网站特定页面的页面对象：
public class GooglePage {
private WebDriver driver;
private String stringLocator = "edffsfds";
@FindBy(how = How.XPATH,using = "//div[@id='header']/ul[1]/li[11]/a")
public WebElement logout;
public GooglePage(WebDriver driver) {
this.driver = driver;
PageFactory.initElements(driver, this);
}
public WebElement getLogout() {
return logout;
}
public void setLogout(WebElement logout) {
this.logout = logout;
}
public String getExampleStringLocator() {
return stringLocator;
}
}
步骤类：
import CucumberNewExcel.transformer.pageObjects.GooglePage;
import cucumber.api.java.en.Given;
import cucumber.api.java.en.When;
public class GoogleSteps {
private GooglePage googlePage;
public GoogleSteps(GooglePage googlePage) {
this.googlePage = googlePage;
}
@Given("^I access \"([^\"]*)\"$")
public void i_access(String arg1) throws Throwable {
//System.out.println("Hello: " + googlePage.getExampleStringLocator());
}
@When("^I click on the signin button$")
public void i_click_on_the_signin_button() throws Throwable {
//System.out.println("Hello: " + googlePage.getExampleStringLocator());
}
}

由于执行我的功能文件时的某种原因，我似乎收到以下异常提示吗？

答案 0 :(得分：1)
之所以发生这种情况，是因为您试图在stepdefination文件中创建构造函数而没有放置picocontainer依赖性。它是黄瓜的依赖注入框架
要么删除构造函数，要么在POM中添加以下依赖项
states = ['n0','n1','n2','n3','n4']
transition_name = [['n0n0','n0n1'],['n1n0','n1n1','n1n2'],['n2n1','n2n2','n2n3'],['n3n2','n3n3','n3n4'],['n4n3','n4n4']]
transition_matrix = [[-4*alpha_n,beta_n],[4*alpha_n,(-3*alpha_n-beta_n),2*beta_n],[3*alpha_n,(-2*alpha_n-2*beta_n),3*beta_n],[2*alpha_n,(-alpha_n-3*beta_n),4*beta_n],[alpha_n,-4*beta_n]]
如果不想限制依赖项的可传递性，则可以删除<!-- https://mvnrepository.com/artifact/info.cukes/cucumber-picocontainer -->
