如何在python中生成動態(參數化)單元測試？我有一些測試數據，并希望為每個項目創建一個單元測試。我的第一個想法是這樣做：import unittest
l = [["foo", "a", "a",], ["bar", "a", "b"], ["lee", "b", "b"]]class TestSequence(unittest.TestCase):
def testsample(self):
for name, a,b in l:
print "test", name
self.assertEqual(a,b)if __name__ == '__main__':
unittest.main()這樣做的缺點是它在一次測試中處理所有數據。我想在飛行中為每個項目生成一個測試。有什么建議嗎？
