For Writing Test Cases

Video Demonstation: https://www.youtube.com/watch?v=rQmeHZdfdYk Step1 : Add dependencies camunda-bpm-process-test-coverage camunda-bpm-assert assertj-core powermock-module-junit4 mockito-core

Step2 : In your test case file register the processEnging by creating object process Enging Rule Ex: public ProcessEngineRule rule = new ProcessEngineRule();

That's it nothing more, happy testing...

Steps for OpenApi/Swagger in Spring Boot Camunda

Step 1: Create a client
Step 2: Download jar from jfrog: https://camunda.jfrog.io/ui/native/camunda-bpm/org/camunda/bpm/camunda-engine-rest-openapi/
Step 3: Extract the jar and add openapi json file to client resources folder
Step 4: Add open-api-generator-maven-plugin with require input directory path and other configurations
Step 5: Add dependencies required by openapi json, and test related libraries - refer pom.xml of camunda-client
Step 6: Do : mvn clean install, verify the code (api, model, auth, apiclient) is generated
Step 7: Define port and camunda engine base-url/rest or base-url/engine-rest in application.yml, will be utilised in Step 8
Step 8: Create configuration with Bean of api client, and require utility, example - CamundaClientConfiguration.java
Step 9: write required methods and in our use case we expose it in ProcessDefinitionUtilityController in the client
Step 10: Do clean install, then run the client application and the camunda engine
Step 11: Test the functionality by hitting /client/start api of client and verify the instance is created in camunda engine for testCaseSample workflow

Steps to use camunda frontend

Step 1: Have your camunda engine running or start this camunda engine
Step 2: update the url of camunda engine in the .env.development if you are running your own camunda-engine, if you are starting camunda engine of this repo only then proceed with default content of configuration file
Step 3: go to custom camunda frontend and run commands: npm install && npm start
Since all are running now
Step 4: In Camunda Engine Application try starting any workflow
Step 5: Verify if content gets populated in the React application
