Python unittest中一个用例使用多套数据的情况怎么处理？

尝试在unittest中一个用例使用多套数据，代码如下，请高手指点一下：
Data.py文件

 #coding=utf-8

adict = {"key1":"value1","key2":"value2","key3":"value3"}
bdict = {"key1":"valuea","key2":"valueb","key3":"valuec"}

Case.py文件

 #coding=utf-8

import unittest,time
import HTMLTestRunner
import Data

class MyTestCase(unittest.TestCase):
    dict = {}

    def SetData(dict):
        MyTestCase.dict = dict

    def testCase1(self):
        print self.dict["key1"]
        print self.dict["key2"]
        self.assertEqual("a","a")

    def testCase2(self):
        print self.dict["key1"]
        print self.dict["key2"]
        self.assertEqual("b","b")

def Suite1():
    suiteTest = unittest.TestSuite()
    MyTestCase.dict = Data.adict
    suiteTest.addTest(MyTestCase("testCase1"))
    suiteTest.addTest(MyTestCase("testCase2"))

    return suiteTest


def Suite2():
    suiteTest = unittest.TestSuite()
    MyTestCase.dict = Data.bdict
    suiteTest.addTest(MyTestCase("testCase1"))
    suiteTest.addTest(MyTestCase("testCase2"))

    return suiteTest


if __name__ == '__main__':
    #确定生成报告的路径
    suite = unittest.TestSuite((Suite1(),Suite2()))

    filePath = "D:/pyResult.html"
    fp = file(filePath,'wb')

    #生成报告的Title,描述
    runner = HTMLTestRunner.HTMLTestRunner(stream=fp,title='Python Test Report',description='This  is Python  Report')
    runner.run(suite)

    fp.close()

问题:
我在Suite1()和Suite2()中分别用了adict和bdict两组数据，但在报告中实际使用的都是bdict中的数据，不知道为啥啊，请高手指点一下，非常感谢。
