tufangorel / spring-boot-junit-jupiter-mock-static-method-with-mockito-inline Goto Github PK

Purpose : Mock static methods in spring boot application with mockito-inline.
Reason : Increase code coverage ratio.

1- Add mockito-core, mockito-junit-jupiter and mockito-inline dependencies into pom.xml.
2- Use Mockito.mockStatic method inside a try-with-resources statement.
3- Before starting the application run mvn clean install to generate mapstruct mapper class.
4- If generated mapstruct mapper class is not recognized by IntelliJ IDE then reload all maven projects.
5- Start Spring Boot REST API by running main method containing class CustomerInfoApplication.java in your IDE.
6- Alternatively you can start your Docker container by following the commands below.
NOT : Execute maven command from where the pom.xml is located in the project directory to create Spring Boot executable jar.

 
$ mvn clean install -U -X 

$ mvn spring-boot:run
