[Clam-devel] Re: Patch for Steps of LoadFrom

[David García Garzón]

In summary for all those patches. Let's keep all the tests in his previous 
form using the 3 parameter constructor which is very convenient and just add 
a new test_TakeArray test method for each kind of that uses the takeArray 
method and asserts the content using the boundsAsString method. Just one test 
for each kind is ok.
