如何在編寫單元測試時有效地模擬對遠程系統調用的響應。有問題的方法是這樣的一個：節點JS - 如何爲存儲單元測試存根肥皂函數調用
client.SomeFunction(input, function(err, result)) {...}
包含它的代碼是在這裏：
'use strict';
var soap = require('soap');
var responseBuilder = require('./responseBuilder');
var errorHandler = require('../src/errorHandler');
/**
* Execute the soap client
*/
exports.executeSoapClient = function (input, headers, wsdlOptions, wsdlPath) {
var soapClientPromise = new Promise(function(resolve, reject){
var response = responseBuilder.buildResponse();
//Call SOAP Client
soap.createClient(wsdlPath, wsdlOptions, function (err, client) {
if (err) {
console.error(err, err.stack);
reject(errorHandler.createError("Unexpected: Could not communication with remote system.", 500));
}
client.addSoapHeader(headers, "", "tkn", "http://siebel.com/webservices");
//This is the function I want to mock out.
client.SomeFunction(input, function (err, result) {
if (err) {
console.error(err);
reject(errorHandler.createError("Unexpected: Unexpected: Could not call remote function on remote system.", 500));
} else {
if (result.Error_spcCode > 0) {
var errorMessage = result.Error_spcMessage + " (" + result.Error_spcCode + ")";
var error = errorHandler.createError("Business rule violation in remote system: " + errorMessage, 401);
console.error(error);
reject(error);
} else {
var successMessage = { flexId: result.FLEXId , message: result.Message };
resolve(response.success(successMessage));
}
}
});
});
});
return soapClientPromise;
};
該代碼最終會爲什麼功能需要來運行作爲AWS LAMBDA，這是以這種方式命名。
