java - Cucumber-JVM 3-使用asMap()将DataTable转换为单个对象

在cucumber-jvm 3.x.x中，我想将只有两列的数据表转换为单个对象。过去它在2.x.x中是自动的，但后来在新的主要版本中已删除。

代码:

// Feature
Scenario: Scan Barcode
    Given I Am At The Login Page
    When I Log In As Valid User
        | group    | gpao     |
        | username | svgpao1  |
        | password | REDACTED |

// Stepdef
@When("I Log In As Valid User")
public void I_Log_In_As_Valid_User(User user) throws Throwable {
    Selenium.enterText(driver, user.getUsername(), "username");
    Selenium.enterText(driver, user.getPassword(), "password");
    Selenium.clickElement(driver, "sign.in");
    LOGGER.debug("User Group=" + user.getGroup());
}

// Configurer
registry.defineDataTableType(new DataTableType(User.class, new TableTransformer<User>() {
    @Override
    public User transform(DataTable dataTable) throws Throwable {
        Map<String, String> map = dataTable.asMap(String.class, String.class);
        return new User(map);
    }
}));

// User - constructor
public User(Map<String, String> map) {
    this.group = map.get("group");
    this.username = map.get("username");
    this.password = map.get("password");
}

堆栈跟踪:

最佳答案

除了@Transpose之外，还需要修改transform方法。

public User transform(DataTable dataTable) throws Throwable {
    return new User(dataTable.asMaps().get(0));
}

@When("I Log In As Valid User")
public void I_Log_In_As_Valid_User(@Transpose SilverUser user) throws Throwable {
    System.out.println(user);
}
