 Default behavior of phases

 Build phases
Validate -> check pom.xml 
compile => convert to class
test -> run the test case
package -> all 3 phase execute then it will create package
integration-test
verify
install -> install package into the maven respository (.m2 or remote repository)

WorkFusion

WorkFusion Overview Bot Classification Our bots address a wide range of automation challenges. To characterize them, WorkFusion developed a taxonomy that describes the complexity and stability of automatons. WorkFusion Automation Complexity Levels Complexity Level, Description 1 API Automation (APIs, File Exchange, Database, ETL) 2 Web Scraping and Crawling (static web applications/sites ) 3 Web Automation (dynamic web applications/sites) 4 Desktop Automation (legacy applications like mainframe, applets, Windows-native applications) 5 Surface Automation (screen-only tools, image recognition) 6 Cognitive Automation (unstructured data) 7 Conversational Automation Bot Development Approach You will find a variety of pre-developed bot tasks available, right out of the box. These tasks are configurable to suit individual use cases. To enhance a bot task or create a new one, both the Web-Harvest library and the Groovy scripting language are available. WorkFusion has pre-defined Web-Ha
