    Hi, Did you test it on the cloud?
    As of now, some of the test apps are not available in SaaS Sandbox. It is recommended to test in Docker version.
    More details:
     
    Hope this helps as well.
    Thanks.

    How can I do automated testing in business central for app source

    Hi Alina,

    I’ve put together a sample project showcasing a full setup for automated testing and validation of Business Central extensions for AppSource submission.

    It includes:

    • A sample extension with automated tests
    • An Azure DevOps pipeline configuration to manage the validation process

    I am unable to download symbols with test runner dependency in app.json. What should I do?

    Normally I use to define this and then take care of all the error messages.

    How can I do automated testing in business central for app source
    To implement automated testing in Dynamics 365 Business Central for an extension you plan to publish on AppSource, you need to follow a structured process that aligns with Microsoft’s requirements and best practices. Below is a complete solution for setting up, writing, and executing automated tests for your Business Central extension.
    ✅ Solution: End-to-End Automated Testing for AppSource Deployment
    1. Understand the AppSource Submission Requirements
    AppSource submissions must include automated tests using AL test codeunits. Microsoft will run your test app in their validation pipeline.
    Key requirements:
    • Include a separate test app (.app file).
    • Tests must cover your extension’s core functionality.
    • Tests must execute without manual intervention.
    2. Set Up Your Development Environment
    Prerequisites:
    • Visual Studio Code
    • AL Language extension
    • Docker (with Business Central sandbox images)
    • Business Central container helper (PowerShell module)
    • Test libraries from Microsoft
    Steps:
    powershell     CopyEdit
    # Pull and run a testable container
    New-BcContainer -accept_eula `
                    -containerName "testcontainer" `
                    -artifactUrl (Get-BcArtifactUrl -type Sandbox -country "w1") `
                    -auth NavUserPassword `
                    -includeTestToolkit `
                    -updateHosts
    3. Create a Separate Test App
    Structure your solution:
    bash    CopyEdit
    MyExtension/
    ├── app/
    │   └── source/
    │       └── ... (main app AL files)
    ├── test/
    │   ├── app.json
    │   ├── launch.json
    │   └── source/
    │       └── Codeunit50100.MyTests.al
    • The test app depends on:
      • Your main app (app.json → dependencies)
      • Microsoft’s test libraries (TestLibraries)
    json   CopyEdit
    "test": "true",
    "dependencies": [
      {
        "id": "YourExtension-ID",
        "publisher": "YourPublisher",
        "name": "YourAppName",
        "version": "1.0.0.0"
      },
      {
        "id": "23de40a6-dfe8-4f80-80db-d70f83ce8caf",
        "publisher": "Microsoft",
        "name": "Test Runner",
        "version": "22.0.0.0"
      }
    ]
    4. Write Test Codeunits Using AL
    Use Microsoft’s test framework (Assert, TestRunner, etc.)
    Example test codeunit:
    al   CopyEdit
    codeunit 50100 "My Test Codeunit"
    {
        Subtype = Test;

        [Test]
        procedure TestMyFunctionality()
        var
            MyRecord: Record "My Table";
        begin
            MyRecord.Insert();
            Assert.IsTrue(MyRecord.IsInserted(), 'Record should be inserted.');
        end;
    }
    Tips:
    • Use [Test] attribute
    • Use Assert methods to validate behavior
    • Create tests that do not require UI interaction
    5. Run and Validate Tests Locally
    Use Docker and the Test Runner to execute tests:
    powershell   CopyEdit
    Invoke-NavContainerCodeunit -containerName "testcontainer" `
                                -tenant default `
                                -codeunitId 50100 `
                                -credential $credential
    Or use the AL Test Tool in VS Code:
    • Ctrl+Shift+P > AL: Run Test Tool
    • Select test codeunits and run them
    6. Prepare the .app Files for Submission
    For AppSource submission:
    • One .app file for your main extension
    • One .app file for your test app
    🔹 Package the test app with only what's needed to test your extension – no test data, no dependencies outside of Microsoft libraries and your app.
    7. Submit to AppSource (Partner Center)
    • Upload both .app files
    • Complete the technical validation steps
    • Microsoft will automatically run your tests in a containerized environment
    You must ensure:
    • All tests pass without errors
    • No user prompts
    • No failures on fresh install/uninstall scenarios
    🔍 Additional Tips
    • Use TestPage objects to simulate user interactions if needed.
    • Validate positive and negative scenarios.
    • Clean up test data within each test.
    ✅ Summary
    Step Description
    1 Understand AppSource test requirements
    2 Set up BC test container with test toolkit
    3 Create a separate test app project
    4 Write AL test codeunits using [Test] methods
    5 Run and validate tests locally
    6 Package .app files (main + test)
    7 Submit to AppSource with passing tests
