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.
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.
Controlling running stubs
You can control stubs that are running in a number of ways.
Viewing stub logs
HCL DevOps Test Virtualization Control Panel (Test Virtualization Control Panel) enables HCL DevOps Test Virtualization (Test Virtualization) users to view the console output of stubs that ran in the selected domain and environment.

  - 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).
  - 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.
    - Publishing stubs
      You can publish a stub to HCL DevOps Test Virtualization Control Panel (Test Virtualization Control Panel), Dockerfile and build context, Kubernetes, or Istio with Kubernetes by using the HCL DevOps Test Integrations and APIs (Test Integrations and APIs) Publish Stubs wizard.
    - Running stubs
      Several methods are available to start and stop the stubs. You can also modify and control stubs while they are running.
    - Modifying running stubs
      If you are using HCL DevOps Test Integrations and APIs (Test Integrations and APIs) to run a stub, you can modify the stub while it is running.
    - Controlling running stubs
      You can control stubs that are running in a number of ways.
      - Locking and unlocking environments
        Locking a HCL DevOps Test Virtualization Control Panel (Test Virtualization Control Panel) environment prevents other users from starting or stopping stubs in that environment.
      - Viewing broken stub messages
        On HCL DevOps Test Virtualization Control Panel (Test Virtualization Control Panel) Environments Dashboard page, if a stub fails to start (irrespective of from where the stub is started) and displays a Broken state, placing your mouse pointer over the stub displays a message about the possible cause for the Broken state. See the Agent logs for more details of the cause.
      - Viewing stub logs
        HCL DevOps Test Virtualization Control Panel (Test Virtualization Control Panel) enables HCL DevOps Test Virtualization (Test Virtualization) users to view the console output of stubs that ran in the selected domain and environment.
      - Query Docker container logs
        You can use the docker logs commands to query Docker container logs.
      - Debugging message-based stubs
        Use the Message Differences window or options available within the stub console display to debug message-based stubs.
    - Behaviors for stubs
      You can create a simple behavior called "echo" that will expose one function and one event for use by a HCL DevOps Test Virtualization (Test Virtualization) stub.
  - 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).

Viewing stub logs

HCL DevOps Test Virtualization Control Panel (Test Virtualization Control Panel) enables HCL DevOps Test Virtualization (Test Virtualization) users to view the console output of stubs that ran in the selected domain and environment.

About this task

You can see the results only if logging to a project results database is enabled when the stub is deployed. To verify that the stub was configured to log, check the Environments Dashboard for Test Virtualization Control Panel (or in HCL DevOps Test Integrations and APIs (Test Integrations and APIs)). If a domain-level project results database override was set up for the selected domain, only the results database specified in the override is used for displaying the console output of stubs in that domain.

If no overrides exist, the results databases for all projects published to the currently selected environment that contain the selected stub are used to display the console output of that stub.

When stub logs are viewed, the connection to the specified project results database is made from the system running Test Virtualization Control Panel. When a stub writes its logs, the connection is made from the system running the agent upon which the stub is running. (This may not be the system running Test Virtualization Control Panel.)

Note: When you set the logging level to Normal, log messages are written to the project results database. When you set it to Debug, more messages (in addition to those found in the project results database, if any) are written to the HCL DevOps Test Integrations and APIs Agent (Test Integrations and APIs Agent) log file. The following procedure applies to viewing the logs that are only stored in the project results database.

Procedure

On Test Virtualization Control Panel Results page, specify the results database and the stub for which, you want to view the log details.
Enter a date range if applicable, and click Search.
Select the stub from the results to display the activities performed.

Note: If the log panel is not displayed or if an empty log panel is displayed, refer to Troubleshooting stubs.
