Describe

UP005 self.assertEquals 是 self.assertEqual 的别名，在 python3.2 之后已经弃用。

For historical reasons, some of the TestCase methods had one or more aliases that are now deprecated. The following table lists the correct names along with their deprecated aliases:

Method Name	Deprecated alias	Deprecated alias
assertEqual()	failUnlessEqual	assertEquals

—— Deprecated aliases

如上所述，可以通过引入 UP005 自动修复 python3.2 后弃用的 self.assertEquals，且转写后不会影响代码的语义，修复命令如下：

# 安装 ruff 0.0.254
pip install ruff==0.0.254
# 确定本 rule 自动修复方案合适，因此直接使用命令自动修复
ruff --select UP005 . --fix
