为什么在运行业力时“ [web-server]：404：/ absoluteC”

Question

我发现了几个类似的问题，但是没有一个建议可以解决我的问题。基本上，他们建议添加一些依赖项（我仅使用本机Web组件，因此不适用于我的情况）或检查路径。我仔细检查，路径是100％正确。我发现警告消息在实际路径之前显示为绝对，这有点奇怪。顺便说一句，这条路真的很完美。

整个代码github

Karma.conf.js

module.exports = function(config) {
    config.set({
        frameworks: ["jasmine"],
        files: [
            "../node_modules/@webcomponents/webcomponentsjs/webcomponents-bundle.js",
            { pattern: "../test/*-test.js", type: "module", included: true }
        ],
        exclude: [],
        preprocessors: {},
        reporters: ["spec"],
        port: 9876,
        colors: true,
        logLevel: config.LOG_INFO,
        autoWatch: true,
        browsers: ["Chrome"],
        singleRun: true,
        concurrency: Infinity
    });
};

import { TestUtils } from "./test-utils.js";
describe("simplest test", () => {
    it("first try (using TestUtils)", async() => {
        const { shadowRoot } = await TestUtils.render("skyscanner-flight-search");
        expect(shadowRoot.querySelector("#firstdiv")).toBeTruthy();
    });
});

因为Karma默认运行在端口9876上，所以它无法深入研究您的项目。相反，它劫持了您的组件，并假定所有内容都可以从该端口访问（不是）....

您可以redirect Karma to your "real ports" using this guide
