批改前：

Unittest应用ddt后生成的测试报告用例名称为：

即就是，以“test_xx_数字”为格局的用例名称，感觉满足不了咱们的测试需要，不够直观。那么怎么批改呢？

查看ddt源码

def mk_test_name(name, value, index=0):    """    Generate a new name for a test case.    It will take the original test name and append an ordinal index and a    string representation of the value, and convert the result into a valid    python identifier by replacing extraneous characters with ``_``.    We avoid doing str(value) if dealing with non-trivial values.    The problem is possible different names with different runs, e.g.    different order of dictionary keys (see PYTHONHASHSEED) or dealing    with mock objects.    Trivial scalar values are passed as is.    A "trivial" value is a plain scalar, or a tuple or list consisting    only of trivial values.    """    # Add zeros before index to keep order        index = "{0:0{1}}".format(index + 1, index_len, )    if not is_trivial(value):        return "{0}_{1}".format(name, index)    try:        value = str(value)    except UnicodeEncodeError:        # fallback for python2        value = value.encode('ascii', 'backslashreplace')    test_name = "{0}_{1}_{2}".format(name, index, value)    return re.sub(r'\W|^(?=\d)', '_', test_name)
  • 从办法mk_test_name中，咱们看到该办法的形容是“Generate a new name for a test case.”，即就是为测试用例创立一个名称，那么改这个办法就行了
  • 办法中返回的是name和index，即"{0}_{1}".format(name, index)
  • 那么就明确了，咱们改返回的内容就行了
