铬角cli npm运行测试

Question

I try to run angular cli karma test in Chrome to get a localhost link. but if i run npm run test it open chrome and close it immediately.

karma.config.js:

module.exports = function (config) {
    config.set({
        basePath:                 '',
        frameworks:               ['jasmine', '@angular/cli'],
        plugins:                  [
            require('karma-jasmine'),
            require('karma-chrome-launcher'),
            require('karma-phantomjs-launcher'),
            require('karma-jasmine-html-reporter'),
            require('karma-coverage-istanbul-reporter'),
            require('karma-junit-reporter'),
            require('@angular/cli/plugins/karma')
        ],
        client:                   {
            clearContext: false
        },
        files:                    [{
            pattern: './src/test.ts',
            watched: false
        }],
        preprocessors:            {
            './src/test.ts': ['@angular/cli']
        },
        mime:                     {
            'text/x-typescript': ['ts', 'tsx']
        },
        coverageIstanbulReporter: {
            reports:               ['html', 'lcovonly'],
            fixWebpackSourcePaths: true
        },
        angularCli:               {
            config:      './.angular-cli.json',
            environment: 'dev'
        },
        reporters:                config.angularCli && config.angularCli.codeCoverage
            ? ['progress', 'junit', 'coverage-istanbul']
            : ['progress', 'junit', 'kjhtml'],
        junitReporter:            {
            outputDir:      'test/target',
            outputFile:     'surefire-reports/TEST-karma.xml',
            suite:          '',
            useBrowserName: true
        },

        port:                     9876,
        colors:                   true,
        logLevel:                 config.LOG_INFO,
        autoWatch:                true,
        browsers:                 [
            //'PhantomJS',
            'Chrome'
        ],
        singleRun:                true
    });
};

How can run npm run test in chrome.

console output:

Answer 1

If your problem is this=> "if i run npm run test it open chrome and close it immediately" That's because of this=> singleRun=true When it is true, Karma captures browsers, runs the tests and exits. So change that to

singleRun: false
