Malicious npm Packages Inject SSH Backdoors via Typosquatted Libraries
Socket’s threat research team has detected six malicious npm packages typosquatting popular libraries to insert SSH backdoors.
做好单元测试是保证代码质量的有效手段。这里介绍一种用示例代码转为测试用例的工具。 这样做可以降低写测试用例的学习和使用成本。
通常在示例代码中我们会用注释给出一个输出预判。
var a = 1;
var b = 2;
console.log(a === b); // false
这样方便复制到控制台编辑运行。
如果写测试用例就会这样:
var a = 1;
var b = 2;
assert.equal(a === b, false);
可以看出来:示例代码和测试代码都有一个输出预判!
那么为何不能用示例代码写测试用例呢?也就是做一下简单的转换即可。
只要做简单的约定就能达到,分别是:
jsdoc
中用 @example
标记,例如:
/**
* @example xxyy
* var a = 1;
* var b = 2;
* console.log(a === b); // false
*/
但这种每行都有 *
的代码,复制粘贴后还需要清理一次,所以我倾向于这种:
/**
* @example xxyy
var a = 1;
var b = 2;
console.log(a === b); // false
*/
为区分运行环境,所以得指定语言,如:
/**
* @example xxyy
```js
var a = 1;
var b = 2;
console.log(a === b); // false
```
*/
/**
* @example 表达式相等预判
```js
var a = 1;
var b = 2;
console.log(a === b);
// > false
```
*/
/**
* @example 表达式结果预判
```js
var a = 1;
var b = 2;
console.log(a + b);
// > 3
```
*/
/*
* @example 表达式类型预判
```js
var a = 1;
console.log(JSON.stringify(a + '1'));
// > "11"
```
*/
/*
* @example 批量表达式预判
```js
for (var i = 0; i < 5; i++) {
console.log(i);
}
// > 0
// > 1
// > 2
// > 3
// > 4
```
*/
/*
* @example 异步执行预判
```js
var a = 1;
setTimeout(function () {
console.log(a);
// > 2
// * done
}, 1000);
a++;
```
*/
/*
* @example 异常执行预判
```js
var a = JSON.parse('#error');
// * throw
```
*/
/*
* @example 浏览器环境
```html
<div></div>
```
```js
console.log(document.querySelector('div') !== null);
// > true
```
*/
/*
* @example jQuery
```css
.red {
background-color: red;
}
```
```html
<div class="red"></div>
<script src="https://code.jquery.com/jquery-3.1.0.min.js"></script>
```
```js
$(function () {
console.log($('.red').css('background-color'));
// > red
// * done
})
```
*/
$ npm install examplejs -g
$ examplejs main.js -o test/main.test.js
var examplejs = require('gulp-examplejs');
gulp.task('example-js', function() {
return gulp.src('src/**.js')
.pipe(examplejs({
head: 'head.js'
}))
.pipe(gulp.dest('test'));
});
