added a main method for test. That way we don't need to change code in each…

theano/tests/main.py

+import unittest
+
+def main(modulename):
+    if 0:
+        unittest.main()
+    elif 1:
+        module = __import__(modulename)
+        tests = unittest.TestLoader().loadTestsFromModule(module)
+        tests.debug()
+    else:
+        testcases = []
+        testcases.append(T_function_module)
+
+        #<testsuite boilerplate>
+        testloader = unittest.TestLoader()
+        suite = unittest.TestSuite()
+        for testcase in testcases:
+            suite.addTest(testloader.loadTestsFromTestCase(testcase))
+        unittest.TextTestRunner(verbosity=2).run(suite)
+        #</boilerplate>
