如何访问 cucumber 的 "step" 对象的 json 的所有 "text" 属性并将它们记录到控制台？

Question

我正在尝试将黄瓜 'step'-对象的步骤描述的 string/regex 记录到控制台。这是一个示例步骤

Given Alice is hungry

...这是步骤定义的第一行

Given( /^Alice is hungry$/, () => {

我正在尝试将 'Given Alice is hungry' 记录到控制台，使用作为参数提供的 'step'-对象的字符串表示，在 webdriverio 的黄瓜特定钩子的上下文中。运行

beforeStep: function ({ uri, feature, step }, context) {
    console.log(`Running "${JSON.stringify(step, null, 4)}"`);
}

...产生此输出：

                        "text": "she will be full"
                    },

然而，当我使用

beforeStep: function ({ uri, feature, step }, context) {
    // eslint-disable-next-line no-undef
    console.log(\`Running step "${step.text}"`);
}

...我得到的只是

 [0-0] Running "undefined"
 [0-0] Running "undefined"

我已经尝试了这两个选项：

console.log(`Running "${step.feature.children.steps.text}"`);
console.log(`Running "${feature.children.steps.text}"`);

在这两种情况下都会产生以下结果：

[0-0] Error in "BeforeStep Hook"
Cannot read property 'text' of undefined

我做错了什么？

Answer 1

举个例子：

${step.feature.children.steps.text}

children是一个数组，所以不能只输入.steps。您需要先访问某个元素，例如 [0].steps.

和steps类似，steps是一个数组：

"steps": [ ... ]

此 ${step.text} 不起作用，因为 step 没有属性文本。它具有以下键：

uri
feature

Answer 2

我接受 pavelsman 的回答作为问题的解决方案。

对于任何想要在执行时将黄瓜步骤记录到控制台的人，只需将其添加到 wdio-configuration 文件中：

let scenarioIndex = 0;
let stepIndex = 0;

beforeStep: function ({uri, feature, step}, context) {
    if(typeof step.feature.children[scenarioIndex] !== "undefined") {
        let keyword = step.feature.children[scenarioIndex].steps[stepIndex].keyword;
        let stepText = step.feature.children[scenarioIndex].steps[stepIndex].text;
        if (stepText !== "") {
            console.log(keyword + stepText);
        }
        stepIndex++;
    }
},
afterScenario: function () {
    scenarioIndex++;
    stepIndex = 0;
},

如何访问 cucumber 的 "step" 对象的 json 的所有 "text" 属性并将它们记录到控制台？

How can I access all the "text" properties of the json of cucumber's "step"-object and log them to the console?
