Design and Development
While designing the processes (Jobs and Routes), developers need to think of how to test them: Talend recommends you to use the Test Case feature: it automatically creates a Test Case with a skeleton in a Test Instance.

A Test Case is an executable test that consists of an immutable part extracted from the initial Job or Route, along with other editable components that form the skeleton of the Test Case.

A Test Instance is a set of data that allows you to run the Test Case with different parameters that you define (input, reference files, etc.).

Note: When building and deploying your project, Test Cases will be generated as JUnit files and thus will be built before the packaging Maven phase.
Best practices:
  • It is recommended to create and use a context adapted to your environment (a Test context to execute test Jobs and Routes with the metadata of this environment, and a Production context to execute Jobs in the Production environment).

  • When the feature is designed and tested, it is recommended to use the Talend Artifact Repository (Nexus, Artifactory) to publish items and retrieve them in the QA and Production environments via Talend Administration Center. See Deploying to QA and Production environments for more information.
