Karma-Coverage always outputs 100% - karma-jasmine

Question

I'm having really hard time starting to write unit tests for my app.
My coverage always reports 100%. I did simple test adn the result should be 50% but karma-coverage doesn't think so. How ever karma progress reports right results but i need to make coverage work.
This is my karma.conf.coffee:
module.exports = (config) ->
config.set
basePath: ""
frameworks: ["jasmine"]
files: [
#"server/*_spec.js",
#"server/*.js",
#"client/app/final/.js"
#"client/*_spec.js"
"test.js"
"test_spec.js"
]
exclude: []
preprocessors: {}
reporters: ["progress", "coverage"]
preprocessors:
"test.js": ["coverage"]
coverageReporter:
type : "html",
dir : "coverage/"
port: 9876
colors: true
logLevel: config.LOG_INFO
autoWatch: false
browsers: [
"Chrome"
#"Firefox" add to package.json::devDependencies:["karma-firefox-launcher"]
#"PhantomJS" add to package.json::dependencies:["phantomjs"] and package.json::devDependencies["karma-phantomjs-launcher"]
]
singleRun: true
concurrency: Infinity
And this is test.js:
function test(a) {
return a
}
function ivo() {
return "ivo"
}
And finally test_spec.js
describe("test", function() {
it("it tests", function() {
expect(test(3)).toEqual(3);
});
});
describe("ivo", function() {
it("it ivos", function() {
expect(ivo()).toEqual("ovi");
});
});
Karma progress result:
karma start

Answer 1

Test coverage indicates the percentage of the source that is tested, not the percentage of tests that pass.
Because you have two functions in test.js and there is a test for each function, the coverage is 100%.
However, only one test actually passes. So your success rate is 50%.

Answer 2

This are the errors
karma start --log-level=DEBUG

This is what i changed in the config:
reporters: ["spec", "coverage"]
plugins: ["karma-spec-reporter", "karma-coverage"]
preprocessors:
"test.js": ["coverage"]
specReporter: {}
