if you are using Eclipse watch your POM dependencies and your Eclipse buildpath dependency on junit

if you select use Junit4 eclipse create TestCase using org.junit package but your POM use by default Junit3 (junit.framework package) that is the cause, like this picture:

see JUNIT conflict

Just update your Junit dependency in your POM file to Junit4 or your Eclipse BuildPath to Junit3

In my case  the culprit was not distinguish the main and test sources folder within pom xml  generated by eclipse maven project    lt build gt       lt sourceDirectory gt src lt  sourceDirectory gt            lt  build gt    If you override default source folder settings in pom file  you must explicitly set the main AND test source folders       lt build gt       lt sourceDirectory gt src main java lt  sourceDirectory gt       lt testSourceDirectory gt src test java lt  testSourceDirectory gt            lt  build gt

Ok  you ve declared junit dependency for test classes only  those that are in src test java but you re trying to use it in main classes  those that are in src main java    Either do not use it in main classes  or remove  lt scope gt test lt  scope gt

I fixed this error by inserting these lines of code     lt dependency gt     lt groupId gt junit lt  groupId gt       lt  -- NOT org junit here -- gt     lt artifactId gt junit-dep lt  artifactId gt     lt version gt 4 8 2 lt  version gt     lt scope gt test lt  scope gt   lt  dependency gt    into  lt dependencies  node    more details refer to  http   mvnrepository com artifact junit junit-dep 4 8 2
