The difference between different testing methods is how states are distinguished (i.e.\ the last part).

In the so-called \emph{partial W-method}, or \emph{Wp-method}, \citep{Fujiwara1991} states are distinguished based on the current state of the hypothesis:

For each state $q \in Q_H$ a set $E_{q}\subset E$ of discriminators is constructed, such that for each state $q' \in Q \setminus\{q\}$ there is a sequence $w \in E_{q}$ that distinguishes $q$ and $q'$, i.e.\ $\lambda_H(q, w)\neq\labmda_H(q', w)$.

For each state $q \in Q_H$ a set $E_{q}\subset E$ of discriminators is constructed, such that for each state $q' \in Q \setminus\{q\}$ there is a sequence $w \in E_{q}$ that distinguishes $q$ and $q'$, i.e.\ $\lambda_H(q, w)\neq\lambda_H(q', w)$.

Then, each trace $uv, u \in S \cdot I, v \in I^{l}$ is concatenated with the set $E_q$ such that $q =\delta_H(q_H, uv)$.

%The method that uses a set of discriminators for all pairs of states is called the \emph{W-method} \cite{chow1978testing}.
