如何使用Jenkins Blue Ocean测试应用程序？

Question

使用create-react-app

创建了一个反应应用

$ npx create-react-app my-app-3

刚刚在其中添加了一个名为Jenkinsfile的文件

#!/usr/bin/env groovy

node('master') {
    try {
        stage('build') {
            sh "npm install"
        }

        stage('test') {
            sh "npm test"
        }
    } catch(error) {
        throw error
    } finally {

    }
}

将其推送到Github并添加Jenkins Blue Ocean的新管道

Jenkins Blue Ocean发现了上面创建的github repo。检查了一下。

然后它自动运行

运行npm test

时出错

我检查了此路径：/var/lib/jenkins/workspace/my-app-3_master-AOH6VCAOPUS4BCUQLNULA3ABCOUVZZEDO2LPJHNW3MX7M2F4KQIA/，仅存在package-lock.json但没有其他文件。所以它无法找到它们。为什么没有提取完整的文件？
