online model based testing using Maven

[victor.l...@gmail.com]

Goal
I am trying to implement Graphwalker in order to conduct online model based testing using Maven.

Background
In the past, I have used Graphwalker for offline model based testing. I am able to input Selenese code in the description for edges and vertices in the yEd model.
Then, generate test cases, and import these test cases into Selenium IDE to be run on the SUT.

What I Would Like To Do
Now, I would like to be able to do the same except with Java code, and run the currently generated test on the SUT while the model is running by using a Selenium driver.
The thing is, I do not want to 'hard code' what the driver should do in Java on a method-to-method basis.
Instead, I would like to embed that Java code in the description for each edge/vertex, as I have done with Selenese code for offline testing.

Example of 'hardcoded' driver solution:
public void e_Search(){
driver.findElement(By.name("Search")).clear();
}

My desired solution would look something like this, except with "Java" instead of "JavaScript" in the AStarPath declaration.

// Get the model from resources

ModelFactory factory = new GraphMLModelFactory();

Model model = factory.create("Amazon", "/models/ShoppingCart.graphml");

GraphWalker graphWalker = new GraphWalker();

graphWalker.addModel(model, new AStarPath(new EdgeCoverage(100)), "JavaScript", new Amazon());

// Start executing the test

graphWalker.execute(model);

Questions:
Is Java code executable from the GraphML file?
Is it possible to import java libraries within the model in yEd?
If so, after instantiating a WebDriver, would it be accessible by all edges and vertices in the model?

[Kristian Karl]

First, I would recommend you to start using https://github.com/GraphWalker/graphwalker-project instead of the old version GraphWalker 2.

>Questions:
>Is Java code executable from the GraphML file? 

In version 2 yes, in later versions it's java script.

>Is it possible to import java libraries within the model in yEd? 

In version 2 yes, in later versions no. 

>If so, after instantiating a WebDriver, would it be accessible by all edges and vertices in the model? 

In version 2 yes, in later versions no. 

However, I would only recommend to put enough code in the models to 'feed' the guards. Keep the code in the models to a minimum.

Have a look at the examples at https://github.com/GraphWalker/graphwalker-example, especially https://github.com/GraphWalker/graphwalker-example/tree/master/java-amazon and https://github.com/GraphWalker/graphwalker-example/tree/master/java-petclinic

is it possible to implement a Web Renderer in the new versions? https://www.youtube.com/watch?v=a8sBYiDKqds&t=18s

[Kristian Karl]

Actually yes, the graphwalker-studio can do this.

Using the PetClinic example, and using the runner: https://github.com/GraphWalker/graphwalker-example/blob/master/java-petclinic/src/main/java/com/company/runners/WebSocketApplication.java

You can connect to the execution using graphwalker-studio: https://github.com/GraphWalker/graphwalker-project/blob/master/graphwalker-studio/README.md

or, download it from: http://graphwalker.github.io/download/

1) Run studio, like java -jar graphwalker-studio-4.0.0-SNAHOT.jar

2) Open a browser: localhost:9090

3) Click the cogwheel, and enter ws://localhost:8887 as the location, and click connect.

That's it

[victor.l...@gmail.com]

Thank you for your replies, much appreciated.
So I added the WebSocketApplication.java file to my project, and reference my model implementation when instantiating the Executor. [Executor executor = new TestExecutor(SomeSmallTest.class);]
I also have the graphwalker-studio, and am able to open a browser to connect to localhost:9090.
When I click the cogwheel and enter ws://localhost:8887 as the location, I receive the following error:

Connection error while connecting to: ws://localhost:8887

I am wondering, do I need to load my test into graphwalker-studio? Or run mvn graphwalker:test before trying to connect to ws://localhost:8887 in order to connect properly?

Thanks again

[victor.l...@gmail.com]

One thing I noticed was that the constructor for WebSocketServer only takes the port as a parameter, while in the example it shows that you pass the executor.getMachine as a second parameter.
Do I need to send that to the WebSocketServer in another way now?

[Kristian Karl]

You need to use latest version 4.0.0-SNAPSHOT of graphwalker. 

This is the constructor you want: https://github.com/GraphWalker/graphwalker-project/blob/master/graphwalker-websocket/src/main/java/org/graphwalker/websocket/WebSocketServer.java#L95

Connect to your test from the browser after you started your test, otherwise you'll see that 'Connection error" string displayed.

The models will be automatically uploaded to the browser from your test.

I found a bug that prevented models being displayed when connected to the test. It's fixed now, but please download the studio jar file once again so you get the latest. Also refresh the browser so it evicts the cache of the old graphwalker javascript.

[victor.l...@gmail.com]

So when trying to run npm install on the graphwalker-project I am receiving the following error

Any idea on how I could go about solving this issue?

[Kristian Karl]

You need to run it from graphwalker-studio/src/main/webapp

The README.md doc in graphwalker-studio assumes you are in the graphwalker-studio folder.

Ah, I see.Have a look here: http://graphwalker.github.io/#latest-development-version-snapshot

You need to add:

Into your pom.xml file in order so it finds the latest snapshot.

Alternative, you run mvn clean -U install form graphwalker-project root folder.

[victor.l...@gmail.com]

Do I add that to the pom.xml file for graphwalker-studio, graphwalker-project, or my project?

[Kristian Karl]

Your own project.

[victor.l...@gmail.com]

After adding that to my pom.xml file I am still receiving the same errors when I try to build the graphwalker-studio-4.0.0.SNAPSHOT.jar file while following the instructions found here: https://github.com/GraphWalker/graphwalker-project/blob/master/graphwalker-studio/README.md

Specificially, the command 'mvn package' is failing.

If its the error as in:

[ERROR] Failed to execute goal on project graphwalker-studio: Could not resolve dependencies for project org.graphwalker:graphwalker-studio:jar:4.0.0-SNAPSHOT: Could not find artifact org.graphwalker:graphwalker-websocket:jar:4.0.0-SNAPSHOT -> [Help 1]

Lets try this:

From the root folder where you cloned the graphwalker-project repository, run:

git reset -f

mvn clean

mvn install

You should not get any problems running the command above. If you do, you have something that is not correct with your environment.

Your jar file for studio will be in: graphwalker-studio/target.

That is interesting!
Are you running JDK 8?
Could you run:
mvn -version

and paste the results here?

So to eliminate as mush as possible, could you try this: (I did this myself just now with no problems)

#Go to en empty folder

cd some_empty_folder

git clone https://github.com/graphwalker/graphwalker-project.git

cd graphwalker-project/

mvn install

java -jar graphwalker-cli/target/graphwalker-cli-4.0.0-SNAPSHOT.jar --version

java -jar graphwalker-studio/target/graphwalker-studio-4.0.0-SNAPSHOT.jar --versio

[victor.l...@gmail.com]

You are correct, it must be some kind of issue with my machine/environment.
I got the same error as before when running those commands on my Mac.
I decided to try a different machine (Windows 10) and it worked with no problems

[victor.l...@gmail.com]

I have switched machines now and am able to run all the commands to generate the latest graphwalker-studio-4.0.0.SNAPSHOT.jar file

I also was able to start using the correct WebSocketServer constructor that I was having issues with earlier. 

I have copied most of the structure from your pet clinic example for my own project.

Now I am running the newest graphwalker-studio jar and going to localhost:9090 in a browser

Then, I run mvn graphwalker:test to start executing my test

I wait until the Firefox driver is set up for my test, and then I click the cogwheel to change the location to ws://localhost:8887.

I am seeing the 'Connection Closed' and then shortly after it changes to 'Connection Error".

Is there something I am missing to get the model to appear?

[Kristian Karl]

Great! :-)

On your MAC, you could have a look at https://stackoverflow.com/questions/7408545/how-do-you-clear-apache-mavens-cache

or, you can also try removing the .m2 repository, 

So to your ws connection problem. I assume that in your code, you have something that looks like:

Executor executor = new TestExecutor(Model_1.class,
                                     Model_2.class);

WebSocketServer server = new WebSocketServer(8887, executor.getMachine());
server.start();

Result result = executor.execute(true);

* Do you get a stacktrace from either you test or graphwalker-studio?

* A longshot maybe, you don't have anything on your machine that uses port 8887 already?

* On your machine, is your test allowed to use the port 8887? I was thinking maybe some Windows Firewall is blocking it?

I will try to find out if there is anything else using port 8887 asap.

I do have windows firewall on. And it says Incoming Connections: Block all connections to apps that are not on the list of allowed apps. 

I don't remember explicitly adding graphwalker to any list of allowed apps, could that be the issue?

etc etc

I am able to connect to port 8887 on the graphwalker-studio, and it gives me updates on the % complete and number of steps taken. But am unable to view the model as it is happening

Regarding Windows firewall, I believe you need to add java to the list of allowed apps.

That sounds like a bug I fixed earlier.

Try using graphwalker-studio from http://graphwalker.github.io/download/ (http://graphwalker.github.io/content/archive/graphwalker-studio-4.0.0-SNAPSHOT.jar) and use that one instead.

You should see the models executing then.

i downloaded the jar from http://graphwalker.github.io/content/archive/graphwalker-studio-4.0.0-SNAPSHOT.jar and replaced my old one. I am still not seeing the models. Could there be a step I am missing?

I run the WebSocketApplication, and as it is starting, I click the cogwheel and connect to the the port. i can see there is something happening between the two programs (updates on % complete and # of steps) but no model appears.

I tried running the GraphStreamApplication which did actually show the model but I ran into the following error midway through execution: 

Exception in thread "main" org.graphstream.graph.EdgeRejectedException: Edge com.company.SomeSmallTest@3feedaece11[com.company.SomeSmallTest@3feedaecn2->com.company.SomeSmallTest@3feedaecn4] was rejected by node com.company.SomeSmallTest@3feedaecn2

I'll create a video of all the steps, and perhaps that will clear out things. Give a little time to create, and upload it.

Have a look at: https://youtu.be/2YXPnmxtGI8

I appreciate you taking out the time to make the video, it has been useful.

I am able to recreate the example in the video on my machine. 

I noticed that you are running the petclinic Spring project before launching the test.

Does the application have to be hosted locally for the graphwalker-studio visualizations to work?

No problems

No. The Spring example project could be hosted on some server anywhere.
