我正在测试Angular唱Jasmine和Karma。 测试似乎完美运行,我能够在Windows控制台中看到结果。但无论如何有一种方法可以使Karma保持打开状态,并且在2秒后不会自行关闭吗?
我有karma.config.js的配置:
const webpackConfig = require('../../../webpack/webpack.test.js');
const WATCH = process.argv.includes('--watch');
module.exports = (config) => {
config.set({
// base path that will be used to resolve all patterns (eg. files, exclude)
basePath: './',
// frameworks to use
// available frameworks: https://npmjs.org/browse/keyword/karma-adapter
frameworks: ['jasmine', 'intl-shim'],
// client:{
// clearContext: false // leave Jasmine Spec Runner output visible in browser
// },
// list of files / patterns to load in the browser
files: [
'spec/entry.ts'
],
// list of files to exclude
exclude: [],
// preprocess matching files before serving them to the browser
// available preprocessors: https://npmjs.org/browse/keyword/karma-preprocessor
preprocessors: {
'spec/entry.ts': ['webpack', 'sourcemap']
},
webpack: webpackConfig(WATCH),
// test results reporter to use
// possible values: 'dots', 'progress'
// available reporters: https://npmjs.org/browse/keyword/karma-reporter
reporters: ['dots', 'junit', 'progress', 'karma-remap-istanbul', 'notify'],
junitReporter: {
outputFile: '../../../../target/test-results/karma/TESTS-results.xml'
},
notifyReporter: {
reportEachFailure: true, // Default: false, will notify on every failed sepc
reportSuccess: true // Default: true, will notify when a suite was successful
},
remapIstanbulReporter: {
reports: { // eslint-disable-line
'lcovonly': 'target/test-results/coverage/report-lcov/lcov.info',
'html': 'target/test-results/coverage',
'text-summary': null
}
},
// web server port
port: 9876,
// enable / disable colors in the output (reporters and logs)
colors: true,
// level of logging
// possible values: config.LOG_DISABLE || config.LOG_ERROR || config.LOG_WARN || config.LOG_INFO || config.LOG_DEBUG
logLevel: config.LOG_INFO,
// enable / disable watching file and executing tests whenever any file changes
autoWatch: WATCH,
// start these browsers
// available browser launchers: https://npmjs.org/browse/keyword/karma-launcher
browsers: ['Chrome'],
// Ensure all browsers can run tests written in .ts files
mime: {
'text/x-typescript': ['ts','tsx']
},
// Continuous Integration mode
// if true, Karma captures browsers, runs the tests and exits
singleRun: !WATCH
});
};

现在,Karma只需启动2-3秒并再次关闭。我在配置中做了什么错误吗?
答案 0 :(得分:1)
通常,CLI将运行Karma,并将singleRun设置为false,以保持浏览器打开。然而,对于Angular 6.0,引入了一个错误,其中karma运行器不再遵循此默认值,并且无论在配置中具有什么,都不会启用watch。如果你想关注它并在发布修补程序时发出通知,那么这里有一个github问题:https://github.com/angular/angular-cli/issues/10711
在此期间,您可以通过从命令行启用观看来运行它。只需使用ng test --watch true
代替ng test
。
所以为了sumarize,你的配置没问题,@ angular / cli @ 6.0.0中只有一个错误,将在即将发布的版本中修复。在此之前,您需要手动告诉它使用--watch true
标志来查看代码。

您是在非WATCH
模式下运行吗?
您有singleRun: !WATCH
,我估计评估为true
。
如果你在WATCH
模式下运行此配置,我打赌它不会关闭。
您可以无条件地设置singleRun: false
。
