Question

我正在实现一个CucumberJS场景，它在两个不同的步骤定义文件中使用多个步骤。第一步是在World上设置一些变量，这些变量必须由另一个步骤定义文件中的步骤使用。

变量设置正确，但当另一个文件上的步骤尝试读取它时，它是未定义的。除了合并步骤定义文件之外，还有任何想法如何解决这个问题？

示例：

world.js

var World = function World() {
  this.client = '';
};

module.exports.World = World;

test.feature

Given a variable A
Then some other step

step1.steps.js

module.exports = function () {
    this.World = require(process.cwd() + '/test/features/support/world').World;

    this.Given(/^a Variable A$/, function () {
        this.client = 'abc';
    });
};

step2.steps.js

module.exports = function () {
    this.World = require(process.cwd() + '/test/features/support/world').World;

    this.Then(/^some other step$/, function () {
        console.log(this.client);
    });
};

Answer 1

You are setting this.client instead of this.World.client. Moreover you should use an object and not a constructor in world.js:

world.js

module.exports = {
    client: ''
};

step1.steps.js

var world = require('./test/features/support/world.js');

module.exports = function () {
    this.Given(/^a Variable A$/, function () {
        world.client = 'abc';
    });
};

step2.steps.js

var world = require('./test/features/support/world.js');

module.exports = function () {
    this.Then(/^some other step$/, function () {
        console.log(world.client);
    });
};

您可以直接参数化您的test.feature：

Given a variable "abc"
Then some other step

现在在您的步骤中传递此变量

step1.steps.js

module.exports = function() {
  this.World = require(process.cwd() + '/test/features/support/world').World;

  this.Given(/^a Variable "([^"]*)"$/, function(variable) {
    this.client = variable;
  });
};

step2.steps.js

module.exports = function() {
  this.World = require(process.cwd() + '/test/features/support/world').World;

  this.Then(/^some other step$/, function() {
    console.log(this.client); // would print abc
  });
};

如何在CucumberJS中的多个步骤定义文件中共享我的World实例？
