Mention any other details that might be useful.

The pre version 1.0.0-beta.30 works very well.

Thanks! We'll be in touch soon.

Can't reproduce with a fresh install. There might be some code to adapt or modules to prune on previous versions.

How does your karma.conf looks like ?

[MateEke]

// Karma configuration file, see link for more information
// https://karma-runner.github.io/0.13/config/configuration-file.html

module.exports = function (config) {
    config.set({
        basePath: '',
        frameworks: ['jasmine', '@angular/cli'],
        plugins: [
            require('karma-jasmine'),
            require('karma-chrome-launcher'),
            require('karma-remap-istanbul'),
            require('@angular/cli/plugins/karma')
        ],
        files: [
            {pattern: './src/test.ts', watched: false},
            "./node_modules/amcharts3/amcharts/amcharts.js",
            "./node_modules/amcharts3/amcharts/serial.js",
            "./node_modules/amcharts3/amcharts/radar.js",
            "./node_modules/amcharts3/amcharts/themes/light.js",
            "./scripts/polarScatter.min.js"
        ],
        mime: {'text/x-typescript': ['ts', 'tsx']},
        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,

        autoWatch: true,
        browsers: ['Chrome'],
        singleRun: false
    });
};

[ruffiem]

Ok, so you may have to adapt your karma.conf.js with the one there.

Also make sure your package.json is up to date with the new dependencies.

Sample:

// Karma configuration file, see link for more information
// https://karma-runner.github.io/0.13/config/configuration-file.html

module.exports = function (config) {
    config.set({
        basePath: '',
        frameworks: ['jasmine', '@angular/cli'],
        plugins: [
            require('karma-jasmine'),
            require('karma-chrome-launcher'),
            require('karma-coverage-istanbul-reporter'),
            require('@angular/cli/plugins/karma')
        ],
        files: [
            {pattern: './src/test.ts', watched: false},
            "./node_modules/amcharts3/amcharts/amcharts.js",
            "./node_modules/amcharts3/amcharts/serial.js",
            "./node_modules/amcharts3/amcharts/radar.js",
            "./node_modules/amcharts3/amcharts/themes/light.js",
            "./scripts/polarScatter.min.js"
        ],
        mime: {'text/x-typescript': ['ts', 'tsx']},
        preprocessors: {
            './src/test.ts': ['@angular/cli']
        },
        coverageIstanbulReporter: {
            reports: [ 'html', 'lcovonly' ],
            fixWebpackSourcePaths: true
        },
        angularCli: {
            config: './angular-cli.json',
            environment: 'dev'
        },
        reporters: ['progress', 'coverage-istanbul'],
        port: 9876,
        colors: true,
        logLevel: config.LOG_INFO,
        autoWatch: true,
        browsers: ['Chrome'],
        singleRun: false
    });
};

[filipesilva]

For some reason #4560 did not get listed in the breaking changes. Sorry about that.

There's instructions there on what you need to update.

[abcfy2]

Thanks. I fixed my issue also.

[Headcult]

Thanks for this, helped me fix my issues as well.
