There should be a way to ask karma to serve a specific directory in a given path

[lgalfaso]

There should be a way to specify karma that a specific content should be served from a specified path. Right now, the only (very hacky) way to do this is

files = [
  {pattern: 'images/*.png', included: false, served: true}
];

proxies =  {
  '/images': 'http://localhost:9876/base/images'
};

That has the big issue that, when the configuration is run, we cannot be positive that karma will run at port 9876 or another port

I do this (using another webserver) to serve my images and to avoid 404 errors. Is this related to these issues ?
#893
#864

@glepretre Even when having a second web server would somehow fix this, I was thinking that being able to do

proxies = {
  '/images': 'file:///somepath/'
};

would be simple enough to solve the issue here.

I view this issue as unrelated to #893 #864 maybe I am not being able to see the connection

[glepretre]

I tried to do :

proxies: {
  '/img/': '/base/app/img/'
},

but I got :

Error: options.host and options.port or options.target are required.

I think it depends on the tests but mine pass anyway with this error

@glepretre I think I like your suggestion the best, this should work:

proxies: {
  '/img/': '/base/app/img/'
},

We just need to fix https://github.com/karma-runner/karma/blob/master/lib/middleware/proxy.js#L37-L42 - if no host/port is defined, use the Karma ones (proxy to Karma itself).
Anybody willing to send a PR for this?

I have tried above fix for karma-warnings. But it was not fixed for me. Could you any one provide me an right solution to the clear the WARN web- server in karma

I've also encountered this issue,
can't I have fake images URL that doesn't exists when I run the tests?

None of those answers solved this annoying 404 warn.

I've this setup in my karma.conf.js:

files: [
    {pattern: 'src/main/webapp/assets/images/**/*.png', included: false, served: true},
    'src/main/webapp/assets/scripts/vendor/*.js',
    'src/main/webapp/assets/scripts/dist/*.js',
    'src/main/webapp/assets/bower_components/angular-mocks/angular-mocks.js',
    'src/main/webapp/assets/partials/**/*.html',
    'src/test/javascript/spec_helper.js',
    'src/test/javascript/**/*.js',
],
exclude: [],
.
.
.
proxies: {
    '/assets/images/diagnostico-assinador/': '/base/',
    '/assets/images/prioridade/': '/base/'
}

with proxies setup I got this warn:

WARN [web-server]: 404: /base/image.png

without proxies setup I got this warn:

WARN [web-server]: 404: /assets/images/diagnostico-assinador/image.png
WARN [web-server]: 404: /assets/images/prioridade/image.png

In case someone still has this problem, here is my fix

Folders:

• src/assets
• karma.conf.js

// karma.conf.js


config.set({
    basePath: '',
    ...
    files: [
      { pattern: 'src/assets/*.jpg', included: false, served: true }
    ]
...

request in the test base/src/assets/myImage.jpg

<img src="base/src/assets/myImage.jpg" />
