Question

I know Ctrl + F9 runs a single file.

How to run them all?

If there is no such thing, how to bind one keyboard shortcut to it?

Answer 1

Why not:

• define a suite of tests, or a target in an ant script (like this one, at the bottom of the article),
  -and then associate a launch configuration (an external one for the ant script)?

You could then use a shortcut to that launch configuration (as in this thread).
One solution for that is to always launch the last application (F11 or Ctrl+F11 )

<target name="tests" depends="compile">
  <py-test pythonpath="${src.dir}" dir=".">
    <fileset dir="${src.dir}">
      <include name="**/*Test.py"/>
    </fileset>
  </py-test>
</target> 

Note: there are other ways to integrate unit testing with pydev, as shown in SO question Continuous unit testing with Pydev (Python and Eclipse)
