You're using junit.framework.Assertinstead of org.junit.Assert.
您正在使用junit.framework.Assert而不是org.junit.Assert.

this method also encounter a deprecate warning:
此方法也遇到弃用警告：
org.junit.Assert.assertEquals(float expected,float actual) //deprecated
It is because currently junit prefer a third parameter rather than just two float variables input.
这是因为当前 junit 更喜欢第三个参数，而不仅仅是两个浮点变量输入。
The third parameter is delta:
第三个参数是delta：
public static void assertEquals(double expected,double actual,double delta) //replacement
this is mostly used to deal with inaccurate Floating point calculations
这主要用于处理不准确的浮点计算

When I use Junit4, import junit.framework.Assert; import junit.framework.TestCase; the warning info is :The type of Assert is deprecated
当我使用 Junit4 时，导入 junit.framework.Assert; 导入 junit.framework.TestCase; 警告信息是：不推荐使用断言的类型
when import like this： import org.junit.Assert; import org.junit.Test; the warning has disappeared
像这样导入时： import org.junit.Assert; 导入 org.junit.Test; 警告消失了
