  - 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.
  - 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).
    - The Events tab
      With the Events tab, you can define how the stub will handle internally and/or externally received events.
    - The Behavior tab
      With the Behavior tab, you can add reusable behavioral entities, that is, pre-programmed intelligence, to your stub.
    - The Properties tab
      With the Properties tab, you can set up states for your stub and input parameters that can determine how the stub behaves when it runs.
    - The Performance tab
      With the Performance tab, you can change the performance characteristics of the stub either by adding delays when a stub runs or by disabling performance optimization.
    - The Session tab
      With the Session tab, you can configure the sharing of the tag data store between workers (instances of the stub), so that messages can be processed based on information that was captured from previously processed messages.
    - The Logging tab
      With the Logging tab, you can define how much information is recorded when the stub is run.
    - The Documentation tab
    - Adding a timer behavior to a stub
      You can use a timer behavior to set a timer event in a stub. After a set time period, the timer event is triggered, the stub receives the event, which it can then respond to. For example, you might have a stub to manage user sessions and you want to add a timer behavior that automatically logs out a user after 30 seconds of inactivity.
    - Example: Adding a repeating timer behavior to a stub
      In this example, you add a repeating timer event to a stub that starts after zero seconds and then repeats every 10 seconds.
    - Sift-and-pass-through capability
      You can filter the messages that a stub receives, separating traffic from client and server applications that need to use the live system as opposed to a virtual system.
    - Performance profiles
      You can use a performance profile to store response time characteristics for a stub over a period of time.
  - 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.

The Logging tab

With the Logging tab, you can define how much information is recorded when the stub is run.

Any information recorded will be logged in HCL DevOps Test Integrations and APIs (Test Integrations and APIs) project results database and on the Test Factory perspective Console window.

The following table describes the list options on the Logging tab.


List Option	Description
None	No information is logged.
Normal	Standard information is logged.
Debug	Verbose information is logged.

Note: If you observe any delays with the stub response time, set the log level to None. This would avoid any delays due to the time taken to log details to the results database.

Note: The default list option displayed on the Logging tab is determined by the setting of the Stub default log level list on the Console page of the Preferences dialog, which is opened by clicking Project > Preferences or Window > Preferences on the menu bar. Therefore, selecting (for the currently selected stub) a different log level on the Logging tab will overwrite the default log level specified in the Preferences dialog but only for that stub.
