在karma runner的命令行中设置config的'browsers'属性

Question

我通常使用browsers = ['PhantomJS']来运行我的规格与karma,因为它比chrome更快,当Chrome在每次启动时在窗口前打开浏览器时,我觉得有点烦人.

但是当我有一个错误而我需要调试时,我将karma.conf.js浏览器更改为['Chrome'].

当我开始业力时,我想设置这个属性,例如:'karma start --browsers = [Chrome]'.

这是真的吗？

你只需要使用--browsers参数,它将覆盖你的配置文件浏览器部分.

$ karma start config/testacular.conf.js --browsers Chrome

其中Chrome是浏览器的名称或二进制文件的路径.

例如,我只配置了一个小型Qt浏览器.如果我使用上面的行,它会运行Chrome.

INFO [karma]: Karma server started at http://localhost:9876/
INFO [launcher]: Starting browser Chrome
INFO [Chrome 24.0 (Linux)]: Connected on socket id DxbVJNX0jIoe1CbaWf9V
Chrome 24.0 (Linux): Executed 74 of 74 SUCCESS (0.443 secs / 0.232 secs)
...

或者,例如,我有火狐beta,极光和我家中的释放.我运行测试版:

$ karma start config/testacular.conf.js --browsers ~/firefox/firefox

$ karma start --help
