Question: I have a java project in eclipse, when I press the `project right click -> run as junit` some tests do not run. I attached a picture, see `YamiMailSenderTest` for example.  

When I try to run the tests directly they are running.  

I am using eclipse 3.7.2.

Any idea?

Answer: 
It's a bit late, but in case anyone finds this via a search engine:

If a Test is run multiple times the results provided by JUnit are indistinguishable for those Tests and thus the results are only displayed for one run. See also the following Eclipse bug report: <https://bugs.eclipse.org/bugs/show_bug.cgi?id=172256>
I had a similar problem. For some reason, the "Run As -> jUnit Test" was always skiping the first test package. I was on an older version of Eclipse and SpringSource.

I moved back to Juno - Version: 4.2.1 and all my test run when I perform: "Run As -> jUnit Test. "
