+
+== Using several test methods
+
+You can use several test methods within a `TestCase` class; they need to start with `test`. When you use method `setUp` it will be executed for each test method. If you only want to "set up" your test environment once of your test case, you need to use class method `setUpClass`.
+
+For example:
+{{{#!py
+# ... imports and such ...
+class TestApi(unittest.TestCase):
+
+    @classmethod
+    def setUpClass(self, port=None):
+        super(TestApi, self).setUpClass()
+        self.env = EnvironmentStub(enable=[
+            'trac.*', 'logwatcher.api'
+        ])
+        # ... more lines ...
+
+    def test_get_logfile_name(self):
+        # ... more lines ...
+
+    def test_get_log_settings_default(self):
+        # ... more lines ...
+
+    @classmethod
+    def tearDownClass(self):
+        super(TestApi, self).tearDownClass()
+        # you should also shutdown environment before deleting directory,
+        # since it closes log files, shutdowns database connection and such
+        self.env.shutdown()
+        shutil.rmtree(dirPath)
