+Okay, so it didn't work, because there is no file by that name. Create such a file, with these contents:
+
+{{{
+rom twisted.trial import unittest
+
+class T(unittest.TestCase):
+    def test_a(self):
+        pass
+}}}
+
+Now install Ned Batchelder's "[http://nedbatchelder.com/code/coverage/ coverage"] tool and run your with code coverage, like this:
+
+{{{
+./bin/tahoe @coverage run --branch --include='src/allmydata/*' @tahoe debug trial allmydata.test.test_fname
+}}}
+
+If you installed coverage from Debian or Ubuntu then you have to name it {{{python-coverage}}}, like this:
+
+{{{
+./bin/tahoe @python-coverage run --branch --include='src/allmydata/*' @tahoe debug trial allmydata.test.test_fname
+}}}
+
+This does the same as running the tests without coverage -- print a list of what happened when each test was run. It also writes out a file named {{{.coverage}}} into the current directory. Run the following command to read that file and produce nice HTML pages:
+
+{{{
+./bin/tahoe @coverage html
+}}}
+
+That will product a directory named {{{htmlcov}}}. View its contents with a web browser.
