javascript - 如何在文件之外读取 mocha 测试套件/案例名称？

Question

在运行测试之前，我需要在文件之外读取/获取 mocha 测试套件/案例文本。例如，我有以下测试套件和测试用例：

describe('Login Page: ', () => { it('should login successfully', () => { ... });});

我想从另一个 js 文件中获取文本：“登录页面：-应该成功登录”。有没有办法导入和访问？什么是最好的解决方案？

简单的解决方案：

    let suiteDesc = {};

    const data  = fs.readFileSync(filePath, {encoding: 'utf8'});
    if(data != undefined) {
        suiteDesc.path = filePath;

        let dataArray = data.split('\n');
        
        let caseDescArray =[];
        dataArray.forEach( l => {
            if(l.trim().startsWith('describe(')) {
                suiteDesc.title = getOnlyTitle(l);
            }
            else if(l.trim().startsWith('it(')) {
                caseDescArray.push(getOnlyTitle(l));
            }
        });
        suiteDesc.cases = caseDescArray;
    }

    return suiteDesc;
} 

// Removes extra js code from line
getOnlyTitle = (str) => {
    let title = '';
    if(str.includes('\`')){
        title = str.substring(str.indexOf('\`')+1, str.lastIndexOf('\`'));
        return removeVarsFromString(title);
    } else if(str.includes('\"')){
        title = str.substring(str.indexOf('\"')+1, str.lastIndexOf('\"'));
        return title;
    } else if (str.includes("\'")){
        title = str.substring(str.indexOf('\'')+1, str.lastIndexOf('\''));
        return title;
    }
}
//Removes all variables  = ${} from the string template 
removeVarsFromString = (str) => {
    if(str.includes('${')){
        let startIndexJsVar = str.indexOf('${');
        let endIndexJsVar = str.indexOf('}') + 1;
        let jsVarString = str.slice(startIndexJsVar, endIndexJsVar);
        str = str.replace(jsVarString, '');

        return removeVarsFromString(str);
    } else {
        return str;
    }
}```
