 ===== Test your driver =====
-When you have written a driver for a new tagset, you should test it. An Interset service module can perform the following tests:
+When you have written a driver for a new tagset, you should test it. The driver package contains a test script called ''driver-test.pl''. When running it, give the driver name as argument, without the ''tagset::'' prefix. You can also use the ''-d'' option to turn on debug messages (list of tags being tested):
+<code>driver-test.pl ar::conll</code>
+Note that only drivers implementing the ''list()'' function can be tested.
+The following tests will be performed:
-  * Get list of possible tags by calling list(). Go through the list and check for each tag that encode(decode($tag))=$tag. While sometimes it can be annoying to try to preserve some obscure information hidden in the tags, this test can also reveal many unwanted bugs. Besides, you should preserve information of your own tagset because people may want to use your driver merely to //access// the tags, instead of //converting// them.
+  * Get list of possible tags by calling ''list()''. Go through the list and check for each tag that ''encode(decode($tag)) eq $tag''. While sometimes it can be annoying to try to preserve some obscure information hidden in the tags, this test can also reveal many unwanted bugs. Besides, you should preserve information of your own tagset because people may want to use your driver merely to //access// the tags, instead of //converting// them.
-To perform the test, run the script ''driver-test.pl'' in the ''tagset'' root folder. Note that the name of the driver to test is currently hard-coded into the source. In future, it will be changed to a command-line argument.
