\subsection{Preflight checklist}
-
Before actual certification is commenced we perform a manual test using a
checklist.
If any of the checks fail we immediately reject the product.
- The checklist is given in the table below.

\subsection{Testing of SUT}
-
- The SUT is a series of services for other computer programs with no end-user
- facing
- interface. Therefore the SUT will be tested solely by calling it's services
- through various automated scripts. An automated test suite will be available
- which executes all these automated scripts and aggregates their results to
- asses whether or not the SUT has passed the test.

The implementation of the SUT is tested using black box testing techniques. A
series of tests asses the correctness of the implementation with regards to the
TCP specification. These tests are specified in Table~\textbf{referentie naar
- tests-tabel}. The test cases aim to cover the most interesting parts of the
- TCP specification.

To cover the TCP specification as complete as possible while still maintaining
a feasible test suite the tests are divided into equivalence partitions. Below
these partitions are given.
\begin{enumerate}
- \item \emph{Number of packets} in request\footnotemark

\item 0 payload packets
\item 1 payload packet
\item n=small payload packets
\item n=big payload packets
\end{enumerate}

- \item Bits flipped in \emph{Payload}
+ \item Correct or incorrect \emph{source port}
+ \item Correct or incorrect \emph{destination port}

\begin{enumerate}

\item Payload with even number of bits flipped
