Welcome
Tester Guide
This guide describes the tasks that you can perform for testing various domains, technologies, and applications. To enable testing, you must configure and enable the environment for testing.
Tester Guide - Service Virtualization
This guide describes the tasks that you can perform for using virtual services or stubs to simulate parts of an environment if the real services are not yet available or because they are difficult or expensive to use. This guide is intended for API Testers.
Creating message-based stubs
In HCL DevOps Test Integrations and APIs (Test Integrations and APIs), there are several methods that you can use to create a message-based stub.

  - DevOps Test Virtualization overview
    HCL DevOps Test Virtualization (Test Virtualization) is software that is used for creating, maintaining, publishing, and running message-based stubs and database stubs.
  - Virtualizing HTTP
    You can simulate an HTTP connection with a virtual service, also known as a stub.
  - Virtualizing HTTPS
    You can simulate an HTTPS connection with a virtual service, also known as a stub.
  - Virtualizing TCP
    You can simulate a TCP connection with a virtual service, also known as a stub.
  - Virtualizing a REST API without recording or synchronization
    You can virtualize REST APIs by using the Recording Studio, or by synchronizing WADL, Swagger, or RAML documents. When none of these options is available, you can still manually virtualize REST APIs that use path parameters.
  - Creating message-based stubs
    In HCL DevOps Test Integrations and APIs (Test Integrations and APIs), there are several methods that you can use to create a message-based stub.
    - Message-based stubs overview
      A message-based stub is essentially an HCL DevOps Test Integrations and APIs (Test Integrations and APIs) resource that listens for incoming messages on a particular transport. A stub can reply to specific messages or message-types, matched according to incoming filters, by using message case actions.
    - Creating an empty stub
      You can create an empty stub. You can add content later by using the stub editor.
    - Creating a stub by using MEP
      You can use the message exchange pattern (MEP) properties for an operation, which define binding and timeout details, to create a stub.
    - Creating a stub populated with data
      You can create a stub based on the structure of the schema that is defined for the operation and the have the response payload populated with data.
    - Stubs with multiple operations
      You can create a single stub to manage multiple operations as a unit. Such a stub is required if you need to share state across several operations.
    - Stub creation by using the Recording Studio
      Use the Recording Studio to create a message-based stub if you have access to a live system from which you can record events.
  - Modifying message-based stubs
    You can use either the Test Editor or the Stub Editor to create, modify, and enhance any legacy or new stubs created by HCL DevOps Test Integrations and APIs (Test Integrations and APIs).
  - Creating and modifying database stubs
    You can create and modify database stubs in HCL DevOps Test Integrations and APIs (Test Integrations and APIs).
  - Configuring stubs to connect to DevOps Test Virtualization Control Panel and the HTTP proxy
    A stub running on its own may not be sufficient in some cases, because it might have dependencies on services such as HCL DevOps Test Virtualization Control Panel (Test Virtualization Control Panel) or the HTTP proxy. If the stub is running on the public cloud and the services are running in the enterprise, you must configure the stub to connect to these services.
  - Publishing and running stubs
    You can publish stubs that are created in HCL DevOps Test Integrations and APIs (Test Integrations and APIs) to HCL DevOps Test Virtualization Control Panel (Test Virtualization Control Panel), Dockerfile and build context, Kubernetes, or Istio, if the stub is based on a supported transport.
  - Viewing results in DevOps Test Virtualization Control Panel
    You can use HCL DevOps Test Virtualization Control Panel (Test Virtualization Control Panel) to display the results of tests that you run in both HCL DevOps Test Integrations and APIs (Test Integrations and APIs) and Test Virtualization Control Panel.
  - Viewing usage statistics of virtual services in DevOps Test Virtualization Control Panel
    Test Virtualization Control Panel collects and stores usage metric data. The metric data might include the number and types of actions that are used, the features that are used in the workbench, details about Operating System or languages set while running, and so forth. You cannot view the metric data on the Test Virtualization Control Panel user interface, but it is available from the underlying implementation. Storage is either managed by H2 or optionally Apache Cassandra.
  - Viewing reports in DevOps Test Hub
    All the project stakeholders can view test reports for multiple testing products from the Results page on HCL DevOps Test Hub (Test Hub). You can access the Results page from a web browser. Therefore, there is no need to install the desktop client.
  - Troubleshooting: DevOps Test Virtualization
    You can use workarounds to common problems that you might encounter when you use HCL DevOps Test Virtualization (Test Virtualization).
Test Manager Guide
This guide describes the tasks that you can perform for tracking the quality of the application. This guide is intended for Test Managers.
Security Considerations for DevOps Test Virtualization
You can take certain actions to ensure that your installation is secure, customize your security settings, and set up user access controls.

Creating message-based stubs

In HCL DevOps Test Integrations and APIs (Test Integrations and APIs), there are several methods that you can use to create a message-based stub.

Creating a stub typically requires a transport and an operation. If you use the Recording Studio method, the operation is optional. See Options for creating test resources.
