Subversion starts looking for myTestBranch at the currently highest
revision, traverses history back to rev 700 and along the way finds
out that your branch came from trunk.

Then it transparently checks out trunk at rev 700.

svn help co says:

  usage: checkout URL[@REV]... [PATH]
  
    If specified, REV determines in which revision the URL is first
    looked up.

So try this instead:

svn co svn+ssh://repos/base/branches/myTestBranch_at_700 ~/myTestCheckout

This should yield an error as you expected.
