unittest（2）-加载用例的3种方式

# 导入测试类执行测试用例
import unittest
from day_20191202.class_unittest import TestMathMethod, TestMulti
# from day_20191202 import class_unittest  # 为了运行模块中多个测试类
import HTMLTestRunner

# ------------------------------
# 方法1 只执行部分用例
# suite = unittest.TestSuite()  # 存储用例
# suite.addTest(TestMathMethod("test_add_two_zero"))
# suite.addTest(TestMathMethod("test_add_two_positive"))  # 添加一个用例,传入的参数是函数名
#
#
# # 执行存储的两个用例
# runner = unittest.TextTestRunner()
# runner.run(suite)
# -----------------------------------------------

# 方法2，TestLoader 按照从上到下的顺序执行测试类中的所有用例
# loader = unittest.TestLoader()  # 加载用例
# suite = unittest.TestSuite()  # 存储用例
# suite.addTest(loader.loadTestsFromTestCase(TestMathMethod))  # 传入测试类名，会自动找到这个类下所有的测试用例
#
# runner = unittest.TextTestRunner()
# runner.run(suite)
# --------------------------------------------------

# 方法3，模块中定义了多个测试类，导入和传参的时候具体到模块名，不用写类名
# loader = unittest.TestLoader()
# suite = unittest.TestSuite()
# suite.addTest(loader.loadTestsFromModule(class_unittest))
#
# runner = unittest.TextTestRunner()
# runner.run(suite)
# ------------------------------------------------------------
# 把测试结果输出到文件中
# 加载用例
# loader = unittest.TestLoader()
# suite = unittest.TestSuite()
# suite.addTest(loader.loadTestsFromModule(class_unittest))

# 执行用例,把测试结果输出到文件中
# with open("test.text", "w+", encoding="utf-8") as file:
#     runner = unittest.TextTestRunner(verbosity=2)
#     runner.run(suite)
# print(file.closed)  # 判断文件是否关闭状态
# --------------------------------------------------------

suite = unittest.TestSuite()
suite.addTest(TestMathMethod("test_add_two_positive"))
suite.addTest(TestMathMethod("test_add_negative"))
suite.addTest(TestMathMethod("test_add_two_zero"))
test_case = [TestMulti("test_multi_positive"), TestMulti("test_multi_negative"), TestMulti("test_multi_zero")]
suite.addTests(test_case)

with open("result.html", "wb") as file:
    runner = HTMLTestRunner.HTMLTestRunner(stream=file, title="单元测试报告", description="未来测试大佬")
    runner.run(suite)
