HCL OneTest™ API reference
HCL OneTest™ API is a scripting-free environment for developing tests for service-oriented architecture (SOA) messaging and business process integration projects. Tests can be built by recording existing system behaviors or from requirements, by entering the data to send and the data that is expected in return.
Schemas
HCL OneTest™ API can handle many types of content. For the product to be able to interpret this variety of content types, it must associate a content format description, or schema with the content.
Creating a DFDL schema
You can use the DFDL schema utility that is provided with HCL OneTest™ API to create a DFDL schema file and apply it to messages. This utility helps you to quickly create a schema with valid format and to specify elements and values by using the DFDL editor.

  - 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.
  - 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, error, and performance 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 this variety of content types, it must associate a content format description, or schema with the content.
    - Adding a schema
      You can add a single schema or a directory that contains multiple schemas to the Schema Library view after which you can apply the schema to messages in your tests. You can specify the type of schema to add or use HCL OneTest™ API to determine the type.
    - ISO 8583 schemas: Overview and structure
      HCL OneTest™ API supports the ISO 8583 standard for messages that originate in financial transaction cards.
    - Adding SWIFT schemas
      When you want to apply SWIFT schema to messages in your tests, you can add additional SWIFT schemas to the Schema Library in the Architecture School perspective of HCL OneTest™ API.
    - COBOL Copybooks overview
      Use COBOL Copybooks in HCL OneTest™ API to test COBOL data files or the applications that produce and consume them.
    - PL/I source file overview
      Use PL/I source files in HCL OneTest™ API to test PL/I data files or the applications that produce and use them.
    - Creating a DFDL schema
      You can use the DFDL schema utility that is provided with HCL OneTest™ API to create a DFDL schema file and apply it to messages. This utility helps you to quickly create a schema with valid format and to specify elements and values by using the DFDL editor.
      - Adding a COBOL copybook as a DFDL schema
        You can add a COBOL copybook as a DFDL schema file and apply it to the messages. This utility helps you to add a schema with a valid format and to specify elements and values.
    - ISO 20022 schema overview
      HCL OneTest™ API supports the ISO 20022 standard, which is the next generation messaging standard for the Society for Worldwide Interbank Financial Telecommunication (SWIFT).
    - Protocol Buffer overview
      Protocol Buffer (also known as protobuf) is a Google framework for efficiently serializing objects for transfer, typically between network endpoints.
    - Creating a Web URL schema
      You can create a Web URL schema to use with REST services by adding URLs to the Schema Library.
    - Creating file schemas
      File schemas can be used to define the contents of one or more files that you intend to write to (publish) or read from (subscribe) in HCL OneTest™ API tests.
    - Applying schemas and formats to messages
      Built in or custom message formats can be applied to any message within HCL OneTest™ API in the same way that schemas can be applied.
    - Applying Integra message handlers
      If you migrated to HCL OneTest™ API from Solstice Integra Suite, you can apply Integra message handlers to HCL OneTest API messages.
    - SWIFT messages
      At any given time, HCL OneTest™ API uses a single version of the Society for Worldwide Interbank Financial Telecommunication (SWIFT) message format standard.
    - Changing schemas
      Over time, it is likely that a schema in use for message construction will change. To update the schema in the HCL OneTest™ API project, use the Synchronization view in Architecture School.
    - Analyzing schemas
      You can analyze certain schema resources, such as XSD or WSDL documents, after they are imported into HCL OneTest™ API.
    - Record layouts
      You can use record layouts in Rational® HCL OneTest™ API to define a file schema to process and validate messages that use a customized schema or format.
  - 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™), 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.
- Security Considerations
