Unit test ServiceLoader

Question

I have a method that uses ServiceLoader to load services using resources.

public List getContextData(int Id)
{
  List li         


        

Answer 1

You need to copy the "provider-configuration file" into your test class directory.

assuming your test class files are located at

test/classes/

you need to copy the "provider-configuration file" to

test/classes/META-INF/services/your.package.ContextPlugin

How to copy the files depend on your build tool (e.g. maven, gradle, ant, ...)

As example for maven you should store them in the test resources folder.

src/test/resources/META-INF/services/your.package.ContextPlugin
