I successfully converted an eclipse (Luna 4.4) Java project to Maven. To use JUnit, I added that as a maven dependency. Here is my resulting project structure as seen in eclipse:

I was expecting that adding JUnit would also create the src/test/Java source folder to hold my JUnit source code, but it's not there. Is this expected? Does one have to manually add these folders after a conversion from a Java project? I saw that when I created a new Maven project in eclipse and added the very same JUnit dependency, the test folder gets created automatically.
src/main/javaas it is recommended by Maven's Standard Directory Layout.
