翻译代码： class AutocorrelationTest(Test):def init(self, seq_length: int ,shift: int = 1): # Generate base Test class self._shift = shift super(AutocorrelationTest, self).init(“Autocorrelation”, 0.01, seq_length) def _execute(self, bits: numpy.ndarray): """ Overridden method of Test class: check its docstring for further information.

这段代码定义了一个类AutocorrelationTest，继承自Test类。它有两个参数：seq_length表示序列的长度，shift表示计算自相关系数时的偏移值，默认为1。在类的构造函数__init__中进行初始化。
