TestOptimal_MBT

API to access TestOptimal Server for execution.

TestOptimal is a Model-Based Testing (MBT) tool, which generates test cases from a state diagram or from a set of variables.

Usage

You may integrate your web project with //TestOptimal// using javascript library: TOServer.js.

For web/javascript, just add one of the following to HEAD tag in your html page:

For //Node.js// project, use following npm command to install //TOServer.js// package: npm install @testoptimal/mbt

Connecting to TestOptimal Server

TOSvr = new TOServer("http://localhost:8888"); TOSvr.setDebugCB((msg)=> console.logMsg ("DEBUG: " + msg), 2); TOSvr.login("myUsername", "myPwd") .then(() => { console.logMsg("connected to TestOptimal server"); }, (err) => { console.logMsg(err); alert("Connection error"); });

State Model Sample Scripts

Creating State Model

var model = new Model ("VendingMachine");
var Welcome = model.addStateInitial("Welcome");
var Q1 = model.addState("25 cents");
var Q2 = model.addState("50 cents");
var Q3 = model.addState("75 cents");
var Q4 = model.addState("100 cents");
var ThankYou = model.addStateFinal("ThankYou");

Welcome.addTrans("add_quarter", Q1).addTrans("cancel", ThankYou);
Q1.addTrans("add_quarter", Q2).addTrans("cancel", ThankYou);
Q2.addTrans("add_quarter", Q3).addTrans("cancel", ThankYou);
Q3.addTrans("add_quarter", Q4).addTrans("cancel", ThankYou);
Q4.addTrans("select_drink", ThankYou).addTrans("cancel", ThankYou);

// TOSvr is the connection object created in Making Connection section above.
TOSvr.uploadModel(model).then (function(){alert("model uploaded");})

Generating Test Cases

TOSvr.genPaths("VendingMachine", "Optimal", 1000).then(printPaths);
function printPaths (sum) {
   console.logMsg(sum);
}

Opening Graphs

// graph types: model, sequence, msc and coverage
// except model graph, all other graphs are available for model execution.
var url = TOSvr.getGraphURL("VendingMachine", "model");
console.logMsg("model graph: " + url);
window.open(url, "ModelGraph");

Online MBT

 var execReq = {
	modelName: "DEMO_RemoteAgent",
	statDesc: "description",
	options: { "autoClose": false }
};
var agentID = "DEMO";
TOSvr.execModel(execReq).then((data) => {
	console.logMsg(data);
	console.logMsg("Registering agent " + agentID);	
	TOSvr.regAgent(execReq.modelName, agentID).then(getNextCmd, errHandler);
});

function getNextCmd() {
   TOSvr.nextCmd(agentID, 2000).then(function(rmtCmd) {
	  if (rmtCmd && rmtCmd.cmd) {
		  var result = {
			result: "I don't know",
			reqTag: "DEMO", 
			assertID: "DEMO-" + rmtCmd.cmd
		 }
		 console.logMsg("received cmd: " + rmtCmd.cmd);
		 console.logMsg("sending result: " + result.result);
		 TOSvr.setResult (agentID, result).then (function(ret) {
			setTimeout(getNextCmd, 1000);
		  }, errHandler);
	  }
	  else modelExecDone();
   }, errHandler);
}

function modelExecDone() {
   console.logMsg("Model execution completed");
}function errHandler (err) {
   console.log("errored");
   console.logMsg(err);
   TOSvr.stopModelExec(execReq.modelName);
}

Retrieve Execution Results

TOSvr.getSummary("DEMO_RemoteAgent").then(function(ret) {console.logMsg(ret);})

Combinatorial Model Sample Scripts

Create DataSet

var ds = new DataSet("DemoDataSet");
ds.addField ("F1", "text", ["aa","bbb"], "", false);
ds.addField ("F2", "int", [1,2,3], "", false);
TOSvr.uploadDataSet (ds).then(console.logMsg, console.logMsg);

Generate Test Cases

TOSvr.genDataTable("DemoDataSet", "pairWise").then(console.logMsg, console.logMsg);

Demo Web Client
