Unit testing Flowable processes with JUnit 5
Testing BPMN processes like application code: FlowableTest and FlowableExtension, @Deployment resources, configuration resources, engine caching across tests, and covering gateways, timers and errors.
Flowable development and testing
Building and testing process applications on Flowable: unit tests, delegates, expressions, variables, REST-based front ends and diagrams.
Thread safety in Flowable Java delegates
Avoiding shared-state bugs in Flowable delegates: how delegate instances and field injection behave, why injected fields can be shared across executions, and safer patterns with expressions and Spring beans.
Using Spring beans and expressions in Flowable models
Calling Spring beans from Flowable expressions and service tasks: delegateExpression versus expression, exposing beans safely, expression functions, Java records and lambda support in Flowable 8.
Flowable transient variables
Passing data through a Flowable process without storing it: transient variables, when they disappear at wait states, using them for large payloads and API responses, and common mistakes.
Building a task list UI on the Flowable REST API
Replacing the removed Flowable 6 task app with your own front end: querying tasks by candidate group, claiming and completing tasks, variables and forms, history views, and API authentication.
Generating Flowable process diagrams
Showing users where a Flowable process stands: diagrams supplied with the deployment or generated from BPMN DI, highlighting active activities, and serving images through the REST API.
