我不太精通 TypeScript 和 Angular2，我一直在尝试 运行 黄瓜的功能使用用 TypeScript 编写的步骤。但是，在执行 steps.ts 文件时，出现以下错误：
[launcher] Running 1 instances of WebDriver
[launcher] Error: TypeError: step.Given is not a function

一个 step_definition 的例子是：

import cucumber = require('cucumber')
import {SignUpPage} from '../pages/signUp.page';
import {SignInPage} from '../pages/signIn.page';
let chai = require('chai').use(require('chai-as-promised'));
let expect = chai.expect;
export = () => {
type Callback = cucumber.CallbackStepDefinition;
let step = <cucumber.StepDefinitions>this;
let index = new SignInPage();
let page = new SignUpPage();
step.Given(/^I am not authenticated$/, (callback:Callback) => {
index.openApp();
callback();
});
step.When(/^I go to register$/, (callback:Callback) => {
index.signUp();
callback();
});
step.When(/^I fill 'name' with '([^"]*)'$/, (value:string, callback:Callback) => {
page.setName(value);
callback();
});
step.When(/^I fill 'email' with '([^"]*)'$/, (value:string, callback:Callback) => {
page.setEmail(value);
callback();
});
step.When(/^I fill 'password' with '([^"]*)'$/, (value:string, callback:Callback) => {
page.setPassword(value);
callback();
});
step.When(/^I fill 'passwordConfirmation' with '([^"]*)'$/, (value:string, callback:Callback) => {
page.setPasswordConfirmation(value);
callback();
});
step.When(/^I press 'Sign up'$/, (callback:Callback) => {
page.submit();
callback();
});
step.Then(/^the register form is validated '(.*)'$/, (valid:string, callback:Callback) => {
let isValid = (valid === 'true');
expect(page.formIsValid()).to.become(isValid).and.notify(callback);
});
};
有什么我遗漏的吗？
在您的 protractor.conf.js 中，您可以从 cucumberOpts
中删除编译器选项
cucumberOpts: {
format: 'pretty',
require: [
'test/features/step_definitions/**/*.steps.ts'
],
//remove this compiler: 'ts:ts-node/register'
},
其次，您的 signUp.steps.ts 应该看起来像这样：
let chai = require('chai').use(require('chai-as-promised'));
let expect = chai.expect;
import {SignUpPage} from '../pages/signUp.page';
import {SignInPage} from '../pages/signIn.page';
import Callback = cucumber.CallbackStepDefinition;
//1. create a class first
class SignupSteps{
private index:SignInPage = new SignInPage();
private page:SignUpPage = new SignUpPage();
this.Given(/^I am not authenticated$/, (callback:Callback) => {
index.openApp();
callback();
});
this.When(/^I go to register$/, (callback:Callback) => {
index.signUp();
callback();
});
this.When(/^I fill 'name' with '([^"]*)'$/, (value:string, callback:Callback) => {
page.setName(value);
callback();
});
this.When(/^I fill 'email' with '([^"]*)'$/, (value:string, callback:Callback) => {
page.setEmail(value);
callback();
});
this.When(/^I fill 'password' with '([^"]*)'$/, (value:string, callback:Callback) => {
page.setPassword(value);
callback();
});
this.When(/^I fill 'passwordConfirmation' with '([^"]*)'$/, (value:string, callback:Callback) => {
page.setPasswordConfirmation(value);
callback();
});
this.When(/^I press 'Sign up'$/, (callback:Callback) => {
page.submit();
callback();
});
this.Then(/^the register form is validated '(.*)'$/, (valid:string, callback:Callback) => {
let isValid = (valid === 'true');
expect(page.formIsValid()).to.become(isValid).and.notify(callback);
});
}
//2. this is really key, expose the class
export = SignupSteps;
您还可以使用 https://github.com/timjroberts/cucumber-js-tsflow 编写更清晰的步骤定义
@查看 https://github.com/samvloeberghs/protractor-gherkin-cucumberjs-angular2 了解完整实施。
干杯
真正的诀窍是修复导出声明，如下所示：
import {CallbackStepDefinition} from 'cucumber';
import {SignUpPage} from '../pages/signUp.page';
import {SignInPage} from '../pages/signIn.page';
let chai = require('chai').use(require('chai-as-promised'));
let expect = chai.expect;
export = function() {
let index = new SignInPage();
let page = new SignUpPage();
this.When(/^I go to register$/, (callback:CallbackStepDefinition) => {
index.signUp();
callback();
});
this.When(/^I set 'name' with '([^"]*)'$/, (name:string, callback:CallbackStepDefinition) => {
page.setName(name);
callback();
});
this.When(/^I set 'email' with '([^"]*)'$/, (email:string, callback:CallbackStepDefinition) => {
page.setEmail(email);
callback();
});
this.When(/^I set 'password' with '([^"]*)'$/, (password:string, callback:CallbackStepDefinition) => {
page.setPassword(password);
callback();
});
this.When(/^I set 'passwordConfirmation' with '([^"]*)'$/, (value:string, callback:CallbackStepDefinition) => {
page.setPasswordConfirmation(value);
callback();
});
this.When(/^I press 'Sign up'$/, (callback:CallbackStepDefinition) => {
page.submit();
callback();
});
this.Then(/^the register form is validated '(.*)'$/, (valid:string, callback:CallbackStepDefinition) => {
let isValid = (valid === 'true');
expect(page.formIsValid()).to.become(isValid).and.notify(callback);
});
};
之后，黄瓜相应地开始了运行。
我不太精通 TypeScript 和 Angular2，我一直在尝试 运行 黄瓜的功能使用用 TypeScript 编写的步骤。但是，在执行 steps.ts 文件时，出现以下错误：

有什么我遗漏的吗？
在您的 protractor.conf.js 中，您可以从 cucumberOpts
中删除编译器选项 cucumberOpts: {
format: 'pretty',
require: [
'test/features/step_definitions/**/*.steps.ts'
],
//remove this compiler: 'ts:ts-node/register'
},
其次，您的 signUp.steps.ts 应该看起来像这样：
let chai = require('chai').use(require('chai-as-promised'));
let expect = chai.expect;
import {SignUpPage} from '../pages/signUp.page';
import {SignInPage} from '../pages/signIn.page';
import Callback = cucumber.CallbackStepDefinition;
//1. create a class first
class SignupSteps{
private index:SignInPage = new SignInPage();
private page:SignUpPage = new SignUpPage();
this.Given(/^I am not authenticated$/, (callback:Callback) => {
index.openApp();
callback();
});
this.When(/^I go to register$/, (callback:Callback) => {
index.signUp();
callback();
});
this.When(/^I fill 'name' with '([^"]*)'$/, (value:string, callback:Callback) => {
page.setName(value);
callback();
});
this.When(/^I fill 'email' with '([^"]*)'$/, (value:string, callback:Callback) => {
page.setEmail(value);
callback();
});
this.When(/^I fill 'password' with '([^"]*)'$/, (value:string, callback:Callback) => {
page.setPassword(value);
callback();
});
this.When(/^I fill 'passwordConfirmation' with '([^"]*)'$/, (value:string, callback:Callback) => {
page.setPasswordConfirmation(value);
callback();
});
this.When(/^I press 'Sign up'$/, (callback:Callback) => {
page.submit();
callback();
});
this.Then(/^the register form is validated '(.*)'$/, (valid:string, callback:Callback) => {
let isValid = (valid === 'true');
expect(page.formIsValid()).to.become(isValid).and.notify(callback);
});
}
//2. this is really key, expose the class
export = SignupSteps;
您还可以使用 https://github.com/timjroberts/cucumber-js-tsflow 编写更清晰的步骤定义
@查看 https://github.com/samvloeberghs/protractor-gherkin-cucumberjs-angular2 了解完整实施。
干杯
真正的诀窍是修复导出声明，如下所示：
import {CallbackStepDefinition} from 'cucumber';
import {SignUpPage} from '../pages/signUp.page';
import {SignInPage} from '../pages/signIn.page';
let chai = require('chai').use(require('chai-as-promised'));
let expect = chai.expect;
export = function() {
let index = new SignInPage();
let page = new SignUpPage();
this.When(/^I go to register$/, (callback:CallbackStepDefinition) => {
index.signUp();
callback();
});
this.When(/^I set 'name' with '([^"]*)'$/, (name:string, callback:CallbackStepDefinition) => {
page.setName(name);
callback();
});
this.When(/^I set 'email' with '([^"]*)'$/, (email:string, callback:CallbackStepDefinition) => {
page.setEmail(email);
callback();
});
this.When(/^I set 'password' with '([^"]*)'$/, (password:string, callback:CallbackStepDefinition) => {
page.setPassword(password);
callback();
});
this.When(/^I set 'passwordConfirmation' with '([^"]*)'$/, (value:string, callback:CallbackStepDefinition) => {
page.setPasswordConfirmation(value);
callback();
});
this.When(/^I press 'Sign up'$/, (callback:CallbackStepDefinition) => {
page.submit();
callback();
});
this.Then(/^the register form is validated '(.*)'$/, (valid:string, callback:CallbackStepDefinition) => {
let isValid = (valid === 'true');
expect(page.formIsValid()).to.become(isValid).and.notify(callback);
});
};
之后，黄瓜相应地开始了运行。
