AltWalker is an open source Model-Based Testing framework that supports running tests written in python3 and .NET/C#.

We've just released a VSCode extension for visualizing your AltWalker or GraphWalker models.
Key features:
- Display your model(s) in a side panel, edit the json file and see the updates reflected on the model(s).
- Snippets to create actions, dependency, edge, generator, guard, properties, requirements, sharedState, vertex, weight.

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.
No issues found with the model(s).

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

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
nullaltwalker 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.

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]"
}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 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"}}

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"] = 1Until this issue is fixed in 4.3.2 you should use 4.2.0.
