@wujunyi2020 vertex_coverage(100) is not achievable with this model.

When you reach a leaf node you reach a dead end and the path can't achieve vertex_coverage(100).

You can try to run altwalker check -m login.json "random(vertex_coverage(100))" to check if the generator and stop condition are valid for the model.

This is a bug in the check command, I'm gonna make an issue for it.

@robert-dezmerean_gitlab it seems that with the same result along with gw offline

(base) [root@localhost ~]# gw check -m login.json "random(vertex_coverage(100))"
No issues found with the model(s).

@robert-dezmerean_gitlab Do you mean that the worflow should be in circle instead of dead leaf?

Robert Dezmerean

@robert-dezmerean_gitlab

Your models can have dead ends but you should be aware of this when choosing a generator and stop conditions.

But if you want to use random(vertex_coverage(100)) or random(never) you should not have dead ends in you models.

Hi guys! I wanted to share an article, presenting an approach of testing the authentication flow of an application with the State Transition Testing technique.
We use AltWalker, GraphWalker and Python to write and execute tests automatically. All the tools used are free and open source.
It can help you to get started with:
• Modeling a web authentication flow
• Writing and executing Python tests with AltWalker
• Running tests in CI
If you think it might help you, check this article: https://altom.com/state-transition-testing-automated-tests-for-authentication-flows/

Hi everyone, I'm trying to setup a basic example from scratch but whenever I try to run altwalker (or the graphwalker) it quits with null error message

 gw online --model models/teststatus.json "random(edge_coverage(100))" --port 8887 --service RESTFUL --verbose
An error occurred when running command: online --model models/teststatus.json random(edge_coverage(100)) --port 8887 --service RESTFUL --verbose
null

altwalker check -m models/teststatus.json  "random(edge_coverage(100))"
No issues found with the model(s).

altwalker verify -m models/teststatus.json  tests
No issues found with the code.

altwalker online -m models/teststatus.json "random(edge_coverage(100))" tests
Running:
ERROR:altwalker.graphwalker:Could not start GraphWalker Service on port: 8887.
ERROR:altwalker.graphwalker:Process exit code: 0
ERROR:altwalker.graphwalker:GraphWalker Service Error: null
GraphWalker Error:

For more information check the log file at: graphwalker-service.log

any clues?

on another topic, I've defined a variable on one edge. this variable is an array. I want now to access it from the python code side but it seems that it's being serialized... what am I missing?

on the model, as actions on the model

nonfinal_statuses = ['TODO', 'EXECUTING'];
final_statuses = ['PASS', 'FAIL', 'ABORTED'];

output:

[2020-09-28 14:41:52.472732] TestStatusModel3.scheduled_run_final Running
Data:
{
    "final_statuses": "[object Array]",
    "nonfinal_statuses": "[object Array]"
}

I'm trying to make a custom reporter and I'd like to make altwalker use it, so that when I run it from the command line, the reporter would be used. I'm struggling to get it working and from what I can see in the code, I'm not sure if this is possible or not. Has anyone some insights on this topic?

Hi everyone, I was trying to port the petclinic example from GraphWalker to AltWalker and it's mostly done. I have just one doubt as I encountered one problem with the underlying model, as it seems that it has edges without "name" attribute. This leads to error whenever trying to generate the code skeleton as altwalker complains about it.
However, when I look at the Java example (using GraphWalker), the model has in fact these edges without any method.
https://github.com/GraphWalker/graphwalker-project/wiki/PetClinic

My main question is: what exactly does it mean to have an edge without a name? It seems to be valid.. and the Java implementation (https://github.com/GraphWalker/graphwalker-example/blob/master/java-petclinic/src/main/java/com/company/modelimplementations/VeterinariansTest.java) for the model doesn't implement any code whatsoever related to this transition.. so, how is it handled?
Should altwalker support these unamed edges also?

Hi team, in the current altwalker visual editor is it possible to reorganize the graph? I don't see a shortcut for that so maybe it's not available?

On another topic, how can I see the seed used by altwalker (which in turn I think comes from GraphWalker) and how can I enforce it as an argument, to ensure that I run the model again in the exact same way?

Hi everyone, I just made available a JUnit XML reporter for AltWalker; it can generate reports in two different ways, so that you can integrate it with your CI/CD tools and even a test management tool if you wish to do so. You can find the code for it in this repo (https://github.com/bitcoder/altwalker-petclinic-example); it requires you to call altwalker programatically using its API.
A full end2end tutorial, showing integration with Jira using Xray is available here: https://docs.getxray.app/display/XRAY/Model-Based+Testing+using+AltWalker+and+Python

Feedback is welcome. Feel free to copy/adapt the custom reporter to your own needs and eventually use parts of it if you wish to include something similar in AltWalker officially. I think that would require cleaning up some code and eventually doing some changes but its a starting point :)

Hi guys, I am getting started with altwalker C# but I encountered this error when I start with quickstart guide altwalker online -x c# tests -m models/default.json "random(edge_coverage(100))" in the docs. Besides, I dont know how I could run without encountering it with JetBrains Rider's run feature but when I entered the site 0.0.0.0:5000 it showed {"error":{"message":"Handler not found"}}

New release of altwalker (0.3.0) on PyPI.

To upgrade to the new version run pip install -U altwalker

Check out the Changelog.

@robert-dezmerean_gitlab

AltWalker should work fine with GraphWalker 4.3.x, but there are issues with global attributes (e.g. global.count), for example something like this won't work in GraphWalker 4.3.x:

def v_start(self, data):
    # to set a new value for a global key 
    data["global.count"] = 1

Until this issue is fixed in 4.3.2 you should use 4.2.0.

Hi everyone, I am currently working on my bachelor thesis project where I am researching how MBT can be deployed in the company I work for. Altwalker seems the most interesting choice because of the visual model editor and the tests in python (our testframework is in Python as well). However, I seem to get stuck on the problem I am trying to solve and I am not sure whether I don't understand Altwalker completely, or have encountered a limitation. The way I have set up altwalker is that for every transition a command is sent over to a remote system using ssh (with Paramiko) that calls a bash shell and then executes another python script. For every command I either get a 0 back indicating it was succesfull, or a return error if something went wrong. If I use every vertex to assert whether the command returned 0, it can run into a problem if one of the commands is unsuccesful. I noticed Altwalker then immediately quits because of the assertion failing. For my system in some cases this is ok, but in some scenario's I would like it to continue on a different path or retry the command. However, I don't see any of these kind of decision nodes or a way to make Altwalker aware to take a different edge at that moment. I could remove the assertion, but then Altwalker will think the command was executed OK, which is also undesirable in some scenarios. Anyone who could help me with this? Thank you in advance

tl;dr;

I want to be able to perform model actions (so I can enable/disable) edges in my model, on the fly.

So far I have been unable to figure out a way of getting that done.

In slightly more detail:
Setting regular actions and guards is all good and well but I need to be able to do this based on the data the actual test code has. Is this something that can be done currently (I am OK with hacky solutions)? If not, should I try to get this into AltWalker or would it be better to talk to the graphwalker people?

Hi -
I need to set a variable inside the model to a random number (e.g. between 1-100). I have a suspicion that this can be done with Read/Update Graph Data, but I need to see an example. The information in https://altom.gitlab.io/altwalker/altwalker/core/tests-structure.html#read-update-graph-data is too short for me to understand how to use it.

Any examples I can look at?

Any other suggestions how I can set a variable (e.g. global.MyVar) to a random number?

thanks, Michael

(I explained the full problem here: https://groups.google.com/g/graphwalker/c/K9xMFLmWxjc in case you are wandering why I need this).

Hello again all! I think I've managed to solve my problem. All I had to do was add %* to the end of the batch file. Now it looks like this: java -jar C:\graphwalker\graphwalker-cli-4.3.1.jar %* I'm not sure if this will work long-term, but it sure seems to fix my problem now!
