我们遇到了同样的问题，我们设法在 ui5-building-tool 步骤中集成 babel 来修复它。
这就是我们的 package.json 的样子：
{
"devDependencies": {
"babel-core": "6.26.3",
"babel-plugin-fast-async": "6.1.2",
"babel-preset-env": "1.7.0",
"karma": "^4.0.1",
"karma-chrome-launcher": "^2.2.0",
"karma-coverage": "^1.1.2",
"karma-ui5": "^1.0.0",
"karma-junit-reporter": "1.2.0",
"rimraf": "^2.6.2",
"start-server-and-test": "^1.4.1",
"@ui5/cli": "^1.5.5",
"@ui5/logger": "^1.0.0",
}
"scripts": {
"start": "ui5 serve -o index.html",
"lint": "eslint webapp",
"test": "karma start",
"build": "npm run test && rimraf dist && ui5 build --a --include-task=generateManifestBundle"
}
}
这就是 ui5.yaml 的样子
specVersion: '1.0'
metadata:
name: app-name
type: application
builder:
customTasks:
- name: transpile
afterTask: replaceVersion
---
specVersion: "1.0"
kind: extension
type: task
metadata:
name: transpile
task:
path: lib/transpile.js
这就是 transpile.js 的样子：
请注意，此文件应放在 root-dir/lib 文件夹中。root-dir 是 ui5.yaml 所在的文件夹。
const path = require("path");
const babel = require("babel-core");
const log = require("@ui5/logger").getLogger("builder:customtask:transpile");
/**
* Task to transpiles ES6 code into ES5 code.
*
* @param {Object} parameters Parameters
* @param {DuplexCollection} parameters.workspace DuplexCollection to read and write files
* @param {AbstractReader} parameters.dependencies Reader or Collection to read dependency files
* @param {Object} parameters.options Options
* @param {string} parameters.options.projectName Project name
* @param {string} [parameters.options.configuration] Task configuration if given in ui5.yaml
* @returns {Promise<undefined>} Promise resolving with undefined once data has been written
*/
module.exports = function ({
workspace,
dependencies,
options
}) {
return workspace.byGlob("/**/*.js").then((resources) => {
return Promise.all(resources.map((resource) => {
return resource.getString().then((value) => {
log.info("Transpiling file " + resource.getPath());
return babel.transform(value, {
sourceMap: false,
presets: [
[
"env",
{
exclude: ["babel-plugin-transform-async-to-generator", "babel-plugin-transform-regenerator"]
}
]
],
plugins: [
[
"fast-async",
{
spec: true,
compiler: {
"promises": true,
"generators": false
}
}
]
]
});
}).then((result) => {
resource.setString(result.code);
workspace.write(resource);
});
}));
});
};
最后这是 karma.conf.js 设置：
module.exports = function (config) {
var ui5ResourcePath = "https:" + "//sapui5.hana.ondemand.com/resources/";
config.set({
// the time that karma waits for a response form the browser before closing it
browserNoActivityTimeout: 100000,
frameworks: ["ui5"],
// list of files / patterns to exclude
exclude: [],
// preprocess matching files before serving them to the browser
// available preprocessors: https://npmjs.org/browse/keyword/karma-preprocessor
preprocessors: {
"root_to_to_files/**/*.js": ["coverage"],
},
// test results reporter to use
// possible values: "dots", "progress"
// available reporters: https://npmjs.org/browse/keyword/karma-reportery
reporters: ["progress", "coverage"],
// 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: false,
// start these browsers
// available browser launchers: https://npmjs.org/browse/keyword/karma-launcher
browsers: ["Chrome"],
// Continuous Integration modey
// if true, Karma captures browsers, runs the tests and exits
singleRun: true,
// Concurrency level
// how many browser should be started simultaneous
concurrency: Infinity,
// generates the coverage report
coverageReporter: {
type: "lcov", // the type of the coverage report
dir: "reports", // the path to the output directory where the coverage report is saved
subdir: "./coverage" // the name of the subdirectory in which the coverage report is saved
},
browserConsoleLogOptions: {
level: "error"
}
});
};
在我们的项目中，此设置适用于 ES6 代码并打印覆盖率。
希望这对您有所帮助。请给我反馈这是如何工作的。
