title: Why do my Junit tests fail when running them all one time?
body: <p>I have a bunch of Junit tests. When I run them individually by right clicking each class and then "run as" -> "Junit test", they all passed. However, if I click a package or click src/test/java to run all at the same time, many of them fails and some passed.</p>
  
  <p>Is this normal? </p>
