Node.js jestjs的npm脚本

我试图用jestjs运行测试，但我很难做到这一点

运行此命令时：

npm testj

npm说我没有这个脚本：

$npm testj

Usage: npm <command>

where <command> is one of:
    access, add-user, ....

npm <cmd> -h     quick help on <cmd>
npm -l           display full usage info
npm faq          commonly asked questions
npm help <term>  search for help on <term>
npm help npm     involved overview

Specify configs in the ini-formatted file:
    /Users/bli1/.npmrc
or on the command line via: npm <command> --key value
Config info can be viewed via: npm help config

npm@2.13.1 /usr/local/lib/node_modules/npm

preprocessor.js

：

var ReactTools = require('react-tools');

module.exports = {
    process: function(src) {
        return ReactTools.transform(src);
    }
};

也许您需要

npm运行testj

只有少数脚本具有速记功能，如

npm-test

var ReactTools = require('react-tools');

module.exports = {
    process: function(src) {
        return ReactTools.transform(src);
    }
};
