@孙善明 If you are relying on files from js-controller (like tools.js), you need to mock the methods in order to use them in unit tests. Remember, those don't have a real js-controller in the background.
This is documented here: https://github.com/ioBroker/testing#adapter-startup-unit-test (in the middle of the code block). You would have to mock getDefaultDataDir, like this:

"{CONTROLLER_DIR}/lib/tools.js": {
    getDefaultDataDir() { return "../../iobroker-data"; }
},

(I'm not 100% sure about the actual return value).

I found the problem here.

 * @param {Partial<ioBroker.AdapterOptions>} [options]
 */
function startAdapter(options) {
	// Create the adapter and define its methods
	dataDir = path.normalize(path.join(utils.controllerDir, require(path.join(utils.controllerDir, 'lib', 'tools.js')).getDefaultDataDir()));

	return adapter = utils.adapter(Object.assign({}, options, {
		name: "serve",

		// The ready callback is called when databases are connected and adapter received configuration.
		// start here!
		ready: main, // Main method defined below for readability

		// is called when adapter shuts down - callback has to be called under any circumstances!
		unload: (callback) => {
			try {
				adapter.log.info("cleaned everything up...");
				callback();
			} catch (e) {
				callback();
			}
		},

solved

dataDir = path.normalize(utils.controllerDir + '/iobroker-data/')
