<b>Test 0</b> : at the initial zoom the WMS layer is in range, you should
|
|
therefore see the 'Loading tiles...' message when loading the page for
|
|
the first time.
|
|
|
|
</p>
|
|
<p>
|
|
|
|
<b>Test 1</b> : If you zoom out by one level (using the zoombar), the WMS
|
|
layer becomes out of range. No tile should be loaded so you shouldn't see
|
|
the 'Loading tiles...' message.
|
|
|
|
</p>
|
|
<p>
|
|
|
|
<b>Test 2</b> : Zoom in by one level to go back to initial state (the WMS
|
|
is back). Open the layer switcher and turn off the WMS layer. No tile
|
|
should be loaded so you shouldn't see the 'Loading tiles...' message.
|
|
|
|
</p>
|
|
<p>
|
|
|
|
<b>Test 3</b> : Keep the WMS layer turned off in the layer switcher. Zoom
|
|
out by one level again. The layer is both invisible and out of range, so
|
|
you shouldn't see the 'Loading tiles...' message.
