我正在使用开放式Web组件karma-esm插件在我的monorepo中运行测试。但是我发现无头chrome抛出一个错误,即出现意外的标记“
这是我的根package.json测试脚本:
"test": "npx karma start --coverage"
这是我的karma.conf.js文件(位于存储库的根目录上,因此未定义基本路径):
const defaultConfig = require('@open-wc/testing-karma/esm-config');
const merge = require('deepmerge');
module.exports = (config) => {
config.set(
merge(defaultConfig(config), {
// define where your test files are, make sure to set type to module
files: [
{ pattern: 'packages/*.tests.ts', type: 'module' },
],
plugins: [
// load plugin
require.resolve('@open-wc/karma-esm'),
// fallback: resolve any karma- plugins
'karma-*',
],
frameworks: ['esm'],
esm: {
babel: false,
nodeResolve: true,
fileExtensions: ['.ts', '.scss'],
customBabelConfig: {
plugins: [
['@babel/plugin-proposal-decorators', { legacy: true }],
['@babel/plugin-proposal-class-properties', { loose: true }],
['css-modules-transform', { extensions: ['.css', '.scss', '.less'] }],
],
presets: [
'@babel/preset-typescript',
],
},
},
coverageIstanbulReporter: {
thresholds: {
global: {
statements: 90,
lines: 90,
branches: 90,
functions: 90,
},
},
},
captureTimeout: 60000,
browserDisconnectTolerance: 3,
browserDisconnectTimeout : 60000,
browserNoActivityTimeout : 60000,
}),
);
return config;
};
除了一些覆盖率阈值以外,它们与建议的配置非常接近。这是命令的输出:

我知道,如果tsconfig.json文件将module设置为ES格式,则可能会发生语法错误。但是我的module设置为CommonJS,我认为这样可以工作。我不能正确克服这个问题吗?有人知道吗?我的tsconfig.json文件如下:
{
"compilerOptions": {
"target": "es5",
"module": "commonjs",
"declaration": true,
"declarationMap": true,
"sourceMap": true,
"removeComments": true,
"strict": true,
"esModuleInterop": true,
"experimentalDecorators": true,
"emitDecoratorMetadata": true,
"baseUrl": "."
},
"include": [
"packages/**/src/**/*.ts",
"declarations.d.ts"
],
"exclude": [
"node_modules"
]
}
谢谢!

....而且有效。去搞清楚!有人在乎为什么会这样吗?我最好的猜测是,从某个时候开始,我开始在全球范围内安装模块……这可能不是一个好主意。
