Welcome to the new Testing panel. This combines the old Skein and Transcript panels. Like them, it records every play through the story. It helps with testing because it compares the text this time with the "blessed" text on previous plays. The panel shows oval "knots" representing turns of play.

The topmost knot is the start position, representing the story before any choices are made.

The purple knot marks the position reached at any given moment in the Story panel.

Each grey knot represents a command typed in, and the text which resulted. Grey means it's not selected: click it to select.

A blue knot is a grey knot that has been selected. Click it again to unselect.

The yellow box shows the text produced the last time the selected (blue knot) commands were typed in. The arrows show which command led to what.

Text is automatically compared against an earlier version known to be correct, called the "blessed" version.

 The tick icon is shown if that turn's text failed to match. Green highlighting shows text added since the "blessed" version, red highlighting shows text removed. (All green must mean there's no "blessed" version, so that all text is new.) If you agree that the current text is correct, click the tick icon. If you don't agree, you'll need to rewrite your story to produce different text next time.

 The cross icon is only shown if that turn's text was correct, that is, if it exactly matched the "blessed" version. Click the cross to "curse" the turn - that removes the blessing.

The red star on a knot means that the text definitely had a "blessed" version but that the most recent play failed to match it - so this is a knot where there's a problem.

The black "threads" between the knots show the sequence of play. Time runs downwards, so later turns are below earlier ones.

Once a turn is played in the Story panel, by typing in a command, another knot will appear here.

As more turns are played in the Story panel, more knots will appear here.

Hover the mouse over a knot to see the pop-up menu button for it - clicking this gives more advanced options.

In addition to Hide/Show Help, the top of this panel has two buttons for advanced users. Save Transcript lets you save out the text from the currently selected thread of play. Play All systematically plays through every variation in the diagram, restarting the story as needed to do so, so that it tests every knot.
