cucumber.runtime.CucumberException：Arity 不匹配：步骤定义

Question

由于步骤定义的 Arity 不匹配错误，我会使用 map 发送测试数据，

下面是我的功能文件，步骤定义和跑步者类

Feature: CRMPRO Login

Scenario: To verify login functionality

Given user is on CRMPRO Login page
When Enters the userName and password
  |userName||password|
  |test||test12|
And click on login button

            // actions
            List<Map<String, String>> s = table.asMaps(String.class, String.class);

            driver.findElement(By.name("username")).sendKeys(s.get(0).get("userName"));
            driver.findElement(By.name("password")).sendKeys(s.get(0).get("password"));

            JavascriptExecutor js = (JavascriptExecutor) driver;
            js.executeScript("arguments[0].click()", buttonLogin);

        }

        @Then("^CRMPRO home page should be displayed$")
        public void crpro_home_page_should_be_displayed() throws Throwable {
            // Write code here that turns the phrase above into concrete actions
            driver.switchTo().frame("mainpanel");
            Assert.assertEquals(driver.findElement(By.xpath("//div[@id='handle_CRMBLOG']")).getText(), "CRMPRO News");

    }

 @RunWith(Cucumber.class)
 @CucumberOptions(features = 
"C:/Users/BR/workspace/com.mavenDemo/src/main/java/GmailLogin.feature", 
 glue = {"com.mavenDemo" })
 public class TestRunner {

}

得到一个错误：

cucumber.runtime.CucumberException: Arity mismatch: Step Definition 'com.mavenDemo.StepDefination.enters_the_userName_and_password(DataTable) in file:/C:/Users/BR/workspace/com.mavenDemo/target/classes/' with pattern [ ^输入用户名和密码$] 用 1 个参数声明。但是，小黄瓜步骤有 0 个参数 []。

我无法解决上述错误，请帮助我解决上述错误。

谢谢

Answer 1

你能不能像下面这样修改你的数据表并尝试执行（中间应该只有一条管道，但你有两条）

当输入用户名和密码时

|userName|password|
|test|test12|
