  • This article describes how to install and start using the BDDFramework tools to implement automated and structured component testing. Component testing in OutSystems covers testing Actions and exposed Services that make up an application's logic.

    Component testing in OutSystems includes the following standard test types:

    • Unit Tests, which developers maintain, focus on individual units of code or components that are owned by a single team
    • Integration Tests, which test whether two or more components work together; these touch a broader application scope than unit testing and the tested code usually belongs to two or more teams
    • API Tests, which verify the contract between consumer and provider and the behavior of your application's existing API endpoints

    Separate BDDFramework tools exist for server-side and client-side testing:

    Both tools provide a similar user experience and the following features:

    • Tests use Gherkin-like syntax and offer a visual representation of test execution
    • You create the test structure using Web Blocks that the tool provides
    • Test code is implemented through actions that are bound to each used Web Block
    • Test Web Blocks are organized into normal screens called Test Suites

    Installing the BDDFramework

    You can install both BDDFramework tools in your OutSystems infrastructure, just as you would other Forge components. You can also install them directly through Service Studio (the OutSystems IDE) or from the online Forge portal.

    1. To install the BDDFramework, log in to Service Studio.
    2. Click the Forge tab in the top left of Service Studio.
    3. In the search box, type BDDFramework. You should see both the server-side and client-side tools.
    4. Select BDDFramework from the results, which brings you to the sever-side tool's page.
    5. Click Install. If you see a confirmation request, confirm the installation.
    6. Repeat these steps to install the client-side tool.

    Once you complete the installation, it's time to start implementing tests.

    Getting started

    Suppose you have an OutSystems application named ACME Services that you want to test. The following tasks walk you through creating a test application for ACME Services.

    Create a test application and module

    1. In Service Studio on the Development tab, click New Application.
    2. Select Start from scratch, and click Next.
    3. Select BDD Framework as the application type, and click Next.
    4. Type ACME Services Tests as the application name and click Next.
    5. On the ACME Service page, change the module name to ACMEServices_Tests, and leave the module type as BDDFramework.

    1. Click Create module. The module imports all the building blocks you need.

    Add a test to your test module

    1. On the Interface tab menu on the right, go to ACMEServices_Test > UI Flows > TestFlow.

    2. Right-click TestFlow and select Add Web Screen.

    3. You may see a message that new templates are loading. When loading completes, click Refresh to update the list of templates. New templates for the BDDFramework appear in the list.

    4. Select New Test Suite, type MyFirst_TestSuite in the name field, and click Create Screen.

      The screen contains a test structure that's added to the UI Flow.

    5. Start implementing the code for your test. See Your Complete Guide to BDD Testing in OutSystems for more information on creating specific tests.
