gulp命令获取参数 [英] gulp command to take parameters
问题描述
我的package.json有这样的脚本
my package.json has scripts like this
{
"scripts": {
"pretest": "npm run tsc",
"test": "gulp e2e",
}
}
我们使用typescript和webdriverIO进行自动化。我想使用gulp,以便我可以将参数传递给我的测试框架。示例:
we use typescript and webdriverIO for automation. I want to use gulp so that i can pass parameters to my test framework. Example:
npm test --suite HomePageTests
然后必须运行与主页相关的规格。
then the specs related to Home page must run.
我有这样的gulp文件
I have the gulp file like this
// gulpfile.js
const gulp = require('gulp');
const Launcher = require('webdriverio/build/lib/launcher');
const wdio = new Launcher(path.join(__dirname,
'src/config/conf.ts'));
// fetch command line arguments
const arg = (argList => {
let arg = {}, a, opt, thisOpt, curOpt;
for (a = 0; a < argList.length; a++) {
thisOpt = argList[a].trim();
opt = thisOpt.replace(/^\-+/, '');
if (opt === thisOpt) {
// argument value
if (curOpt) arg[curOpt] = opt;
curOpt = null;
}else {
// argument name
curOpt = opt;
arg[curOpt] = true;
}
}
console.log("arg", arg)
return arg;
})(process.argv);
gulp.task('e2e', () => {
return wdio.run(code => {
process.exit(code);
}, error => {
console.error('Launcher failed to start the test',error.stacktrace);
process.exit(1);
});
});
所以当我直接打电话给gulp时
So when I call gulp directly like
gulp e2e --suite HomePageTests
它打印为
suite: HomePageTests
但如果我使用
npm test --suite HomePageTests
打印失败,打印 gulp e2e HomePageTests
问题
- 如何从npm传递这些值以使gulp理解
-
如果我传递给gulp e2e --server staging等其他值,并希望在我的规范文件中使用变量staging,如
- How do I pass these values from npm to make gulp understand
If I am pass to another value like gulp e2e --server staging and would like to use the variable "staging" in my spec file like
if server = == staging
{
//执行此操作
}其他{
//执行
}
if server=== staging
{
// do this
} else {
// do that
}
我应该如何将它们从gulp文件传递到我的spec文件?
How should I pass them from gulp file to my spec file?
谢谢!!
推荐答案
您可以使用 yargs依赖
var argv = require('yargs').argv;
gulp.task('test', function(){
console.log(argv.arg);
});
然后如果你在gulp上运行命令就像这样传递arg
then if you run a command on a gulp passing the arg like this
gulp test --arg HomePageTests
它将在控制台上输出 HomePageTests
