Reference Guide
This guide provides the topics to help the API tester use the product by using the user interface, commands or scripts. This guide is intended for API testers.
Test Factory
The Test Factory perspective is one of the main areas in HCL OneTest™ API. You can create all the tests and the required artifacts/data to support them.
Tests: Overview and tasks
Tests are the fundamental building blocks of integration and SOA testing. A test sends an input message to an external service or system in a protocol-specific way and validates the reply against an expected result.
Message cases
Message cases are used in Message Switch actions. To add a message case to an existing message switch, right-click the message switch and select Add Message Case from the menu.

- HCL OneTest™ API overview
  This section provides an overview of HCL OneTest™ API, including information about projects and files, the HCL OneTest API user interface, environments, and project settings and preferences.
- Architecture School
  Use the Architecture School perspective to build a system under test by using the logical, physical, and synchronization views. You can also use this perspective to manage the schemas available in your project.
- Recording Studio
  With HCL OneTest™ API, you can record events (messages or database interactions) sent to and from the system under test. Use Recording Studio to control what parts of the system should be recorded. These parts could be specific parts of the system infrastructure or specific services using that infrastructure. You can then use the recorded events as a source of tests and other interactions with the system. In Recording Studio, you can record the traffic over a number of different transports.
- Test Factory
  The Test Factory perspective is one of the main areas in HCL OneTest™ API. You can create all the tests and the required artifacts/data to support them.
  - Tests: Overview and tasks
    Tests are the fundamental building blocks of integration and SOA testing. A test sends an input message to an external service or system in a protocol-specific way and validates the reply against an expected result.
    - Test phases
      A new, empty test always consists of three basic phases: Initialize, Test Steps and Tear-down.
    - Test views
      Two views are available for a test, the Technical View and the Business View .
    - Creating a single empty test
      You can create a single empty test in HCL OneTest™ API, and you must add the test steps to the created test before you can run the test.
    - Creating a single test by using MEP
      You can create a single test from a Message Exchange Pattern (MEP) in HCL OneTest™ API from the Test Factory view. An operations MEP defines the pattern, schema, and binding for messages that are exchanged by the operation. You can create a test that adheres to the rules defined in the MEP.
    - Creating multiple tests by using MEP
      You can create multiple tests from a Message Exchange Pattern (MEP) in HCL OneTest™ API from the Test Factory view. An operations MEP defines the pattern, schema, and binding for messages that are exchanged by the operation. You can create multiple tests that adhere to the rules defined in the MEP.
    - Creating a test from a template
      After you create a test template, you can quickly create new tests from it.
    - Creating tests by pasting
      You can create one or more tests by pasting one or more lines of text that are currently on the clipboard. New tests are named according to the pasted text. Each line of text on the clipboard creates a unique test, and the tests are created within the component or folder that is selected when pasting.
    - Creating tests from recorded events
      Tests can be created by using events that are captured in the Recording Studio.
    - Contract testing
      When you want to ascertain the validity of the responses sent from a server to the requests by a client in a system under test, you can define a schema for the expected messages, and then the incoming messages can be validated against the defined schema for adherence to a contract. You can create Contract tests in HCL OneTest™ API that validate the schema in the incoming messages for conformance with the schema defined for the messages.
    - Setting the Test properties by the input and output tags
      Use the Properties tab to define which tags are to be available on the input and output interface for the selected test.
    - Overriding the inherited integration for change management applications
      HCL OneTest™ API can be integrated with OSLC-compliant change management systems for raising defects within the context of a HCL OneTest API test asset.
    - Changing the contents of a test
      You can add or edit test actions, change the test action type, enable or disable test actions, and save messages as requirements.
    - Filtering header values
      If you are using a stub to test more than one web service from a single URL, you can use header values to distinguish between the services.
    - Monitoring a log file during a test
      If a log file is configured on any of the bound infrastructure components of the project, that file can be monitored during the execution of a test.
    - Example: Monitoring a remote log file
      In this example, you add a log file to a database server. With the log file added, you can then monitor that file when you run a test.
    - The Tag Data Store
      The Tag Data Store, which is accessed from the menu anywhere within a test, is the repository and access point for all of the data tags that are available to a test.
    - Message cases
      Message cases are used in Message Switch actions. To add a message case to an existing message switch, right-click the message switch and select Add Message Case from the menu.
    - Pass paths
      You can define action sequences to be carried out when a subscription-based action passes (that is, Subscribe, Receive Request, and Receive Reply).
    - Failure paths
      To specify that a test take different steps when a specific action fails, you can create a failure path and define sequences of actions for it. For example, a Publish action can fail to publish a message, or a subscriber can fail to subscriber properly or an incoming message might not pass validation.
    - Running or scheduling the running of a test
      You initiate a test execution in the Test Factory, but the test is run in the Test Lab perspective. After you start a test, the Test Lab perspective is displayed, from where you monitor the tests execution. A test can be run either in the current environment or in any other environment.
  - Test Suites: Overview and tasks
    A Test Suite represents a group of tests, test suites, and scenarios. Any combination of these items can be included, but a test suite must always contain at least one scenario and one test. Test suites are used mainly to construct reusable, packaged regression tests that can be run across multiple environments, or repeatedly within the same environment.
  - Stubs: Overview and tasks
    Stubs can be used to simulate services that you are unable to use or that are otherwise unavailable.
  - The Action Editor
    The Action Editor is used to modify the actions that are contained within a test or stub.
  - Creating a test template
    To save time when you are creating tests, you can create a template of test sequences that can be used to quickly create a number of pre-defined tests.
  - Test data sources
    You can configure test data sources that can drive a test template or a test by using several different instances of data. In this way, you can parameterize your tests, substituting specific data from a pre-configured source in different test iterations. You can also use test data to validate the results that are returned by different test actions.
- Test Lab
  You use the Test Lab to execute test assets, repair tests, and open test assets for editing directly from this perspective. You can execute all of the tests, test suites, and stubs that are created in Test Factory.
- Results Gallery
  You use the Results Gallery perspective to view an execution summary and detailed coverage, and error reports for executed test suites and for test cases that were executed within a suite or as part of a test cycle.
- Messages
  HCL OneTest™ API can publish and subscribe to messages as part of a test. A message normally consists of two parts: a header and a body. The header usually adheres to a predefined logical construction, while the structure of the body can be more arbitrary.
- Schemas
  HCL OneTest™ API can handle many types of content. For the product to be able to interpret the variety of content types, it must associate a content format description, or schema with the content.
- Database resources, connections, and bindings
  HCL OneTest™ API can interact with any database that supports connectivity through the JDBC specification. These interactions can be used to extract or update data where necessary, and test data sets can be taken directly from database table content.
- Identity stores and SSL
  An identity store can group a collection of one or more certificates that can be used in HCL OneTest™ API to validate and authenticate connections that use SSL. After you create an identity store, you can use it to enable SSL communications in various messaging transports.
- Scripting within tests and stubs
  You can use scripts in HCL OneTest™ API that include the HCL OneTest API legacy scripting language, ECMAScript (such as JavaScript™), Chai, or any third-party scripting language that you install.
- External tools
  HCL OneTest™ API is primarily GUI-based, but you can also run or view tests, suites, and stubs outside of the HCL OneTest API.
- Test actions
  Actions are the building blocks of a test. A test consists of a series of steps and each step is an action. Actions can be defined for tests and stubs.
- Formatting and parsing date-time patterns
  For some fields in HCL OneTest™ API, you can define patterns for date-time formatting. Pattern letters are repeated, as their number determines the exact presentation of the date-time information that they represent.
- The Add Numbers service
  The Add Numbers service, included with HCL OneTest™ API, provides a simple way to generate messages that you can observe with topology discovery or capture in Recording Studio.

Message cases

Message cases are used in Message Switch actions. To add a message case to an existing message switch, right-click the message switch and select Add Message Case from the menu.

Each message case is configured to match a specific message that was captured more generically by the message switch. When combined, the message switch and any one of its message case actions work like a complete Subscribe action. The message switch specifies the general transport and destination information, while the message case performs detailed filtering and contains the assert and store options.

The Message Case window

If the message switch is part of a stub, the Config tab provides the option to check and set the state of the stub. Under Start State and Finish State, you can select one of the available session states (configured under the Properties tab of the stub). If a start state is selected, the actions within the message case are executed only if the stub session equals the selected state. If a finish state is selected, the session is set to that state once the actions under the message case finish executing.

Additionally, before any of the actions within the message case can be executed, any filter expressions that are added under the Config tab must evaluate to true. At the very least, the expressions must evaluate to one if the OR Expressions option is selected. Filter expressions are available for message cases in both tests and stubs.

Specify the type of scripting language you want to enter for the filter expression:

ECMAScript: Any standard ECMAScript, such as JavaScript™. Enter or paste the script for the condition in the space provided. The script must evaluate to either true or false.
Legacy: To use a built-in or custom function, click Add, right click in the space provided, click Select Function, and choose the function to add.

Click Test to see the output of the filter expressions, using the current values of any included tags.

The standard filter, assert, and store actions are available under the remaining tabs within the message case.

The message case contains its own actions that can be carried out when a matching message is received.
