黄瓜函数有 1 个参数，应该有 2 个（如果同步或返回承诺）

Question

我有一个 feature 文件：

  Scenario: List all accounts in the tenant
    Given that Keith has navigated to the tenant account list
    When he views the accounts in the table that includes name, name2, name3
    Then he should also see 1,2,3,4 in the list

我有一个步骤定义文件：

this.When(/^(.*?) views the accounts in the table that include (.*)$/, (accountInformation: string) => {
    return stage.theActorInTheSpotlight().attemptsTo(
      ViewAllAccountNames.inTheTableOf(accountInformation)
    );   });

这是在步骤定义中调用的 ViewAllAccountNames class

constructor(private accName: string) {

  }
    static inTheTableOf(accName: string) {
        return new ViewAllAccountNames(accName);
    }
    performAs(actor: PerformsTasks): PromiseLike<void> {
        return actor.attemptsTo(
          See.if(AccountTable.isDisplayingAll, includes(this.accName))
        );
    }

所以鉴于所有这些信息，我运行 test and keep getting 函数有 1 个参数，应该有 2 个（如果同步或返回承诺）或 3（如果接受回调）（下面是错误）

我无法判断它是否破坏了参数或我的代码中的错误

有什么想法吗？

它期望回调参数作为第二个参数。有两种方法可以解决这个问题。

将回调作为参数传递：

this.When(/^(.*?) views the accounts in the table that include (.*)$/, (accountInformation: string, callback) => {
    stage.theActorInTheSpotlight().attemptsTo(
        ViewAllAccountNames.inTheTableOf(accountInformation)   
    ).then(callback, callback);
});

使函数 return 成为承诺：

this.When(/^(.*?) views the accounts in the table that include (.*)$/, function(accountInformation: string) {
    return stage.theActorInTheSpotlight().attemptsTo(
        ViewAllAccountNames.inTheTableOf(accountInformation)
    );   
});

黄瓜函数有 1 个参数，应该有 2 个（如果同步或返回承诺）

cucumber function has 1 arguments, should have 2 (if synchronous or returning a promise)
