Hi folks,

Let me summarize the yesterday's discussion in a few keys points:

   - Greg's proposal aims at simplicity and is useful mainly for test cases
   which can be written in a few minutes. More complex test cases are not
   suitable for the YAML approach.
   - The above implies that the YAML based test cases would be supported
   alongside the existing approach. This fast way to implement simple test
   cases would likely be a valuable addition.
   - The big picture idea behind the YAML test cases is to take an
   application with interactive input, send commands, collect output and
   compare the output with expected string(s).
   - Greg may be able to make the code available and may assess how to
   integrate it with DTS.

Regards,
Juraj

&gt; Hello Honnappa,<br>
&gt; <br>
&gt; [snip]<br>
&gt; <br>
&gt; &gt; Hi Gregory,<br>
&gt; &gt;=C2=A0 =C2=A0 =C2=A0 =C2=A0 I do not fully understand your proposa=
l, it will be helpful to join the DTS<br>
&gt; meetings to discuss this further.<br>
&gt; &gt;<br>
&gt; <br>
&gt; Agree, let&#39;s discuss the proposal details during the DTS meeting.<=
br>
&gt; <br>
&gt; &gt; YAML has wide support built around it. By using our own text form=
at, we will<br>
&gt; have to build the parsing support etc ourselves.<br>
&gt; &gt;<br>
&gt; &gt; However, YAML is supposed to be easy to read and understand. Is i=
t just a<br>
&gt; matter for getting used to it?<br>
&gt; &gt;<br>
&gt; <br>
&gt; I selected YAML for 2 reasons:<br>
&gt;=C2=A0 =C2=A0 * Plain and intuitive YAML format minimized test meta dat=
a.<br>
&gt;=C2=A0 =C2=A0 =C2=A0 By the meta data I refer to control tags and marku=
p characters<br>
&gt;=C2=A0 =C2=A0 =C2=A0 that are not test commands.<br>
&gt;=C2=A0 =C2=A0 * YAML has Python parser.<br>
I have mis-understood your proposal. I agree with your above comments.<br>
+1 for the proposal.<br>
<br>
&gt; <br>
&gt; Regards,<br>
&gt; Gregory<br>
