karma test suite empty from Chrome - unit-testing

Question

I have a problem with setting up units tests in project. When I run tests with IE everything works fine I can see 4/4 tests executed. With chrome i am getting error Empty test suite. Chrome is launched but it looks like it can;t find tests and tests for chrome are not executed.
Karma.config.js
module.exports = function (config) {
config.set({
basePath: '',
frameworks: ['jasmine', 'angular-cli'],
plugins: [
require('karma-jasmine'),
require('karma-chrome-launcher'),
require('karma-ie-launcher'),
require('karma-remap-istanbul'),
require('angular-cli/plugins/karma')
],
files: [
{ pattern: './src/test.ts', watched: false }
],
preprocessors: {
'./src/test.ts': ['angular-cli']
},
remapIstanbulReporter: {
reports: {
html: 'coverage',
lcovonly: './coverage/coverage.lcov'
}
},
angularCli: {
config: './angular-cli.json',
environment: 'dev'
},
reporters: ['progress', 'karma-remap-istanbul'],
port: 9876,
colors: true,
logLevel: config.LOG_INFO,
autoWatch: true,
browsers: ['Chrome'],
singleRun: true
});
};
test.ts is just searching unittests within app folder:
.then(() => require.context('./', true, /\.spec\.ts/))

Answer 1

I found that the issue was with reporters section, after 2 days of agony I changed file to
reporters: config.angularCli && config.angularCli.codeCoverage
? ['progress', 'karma-remap-istanbul']
: ['progress'],
removed mime section and it works!
