4. Write a JUnit unit test class, as shown below. first declare a variable

Peocessingengine processingengline;

Instantiate processingengline = configuration. getprocessingengline ();

Obtain the repositoryservice processingengine. getrepositoryservice ();

Publish a process definition and return the string deploymentid = repositoryservice. createdeployment (). addresourcefromclasspath ("file name"). Deploy ();

View the definition process: List list = repositoryservice. createprocessdefinitionquery (). List ();

You can use the cascade deletion method to delete a defined process based on the process ID:

Repositiryservice. deletedeploymentcascade (deploymentid );
