你是如何扩展你的Assert类的

import static org.junit.Assert.*;

public class MyAssert extends Assert {
    public static void assertGreaterThan(int expected, int actual) {
        if (actual <= expected) {
            fail("Expected " + actual + " to be greater than " + expected);
        }
    }
}

import org.junit.Test;

public class MyAssertTest {
    @Test
    public void testAssertGreaterThan() {
        MyAssert.assertGreaterThan(5, 10);
    }
}

import unittest

class MyAssert(unittest.TestCase):
    def assertGreaterThan(self, expected, actual):
        if actual <= expected:
            self.fail("Expected {} to be greater than {}".format(actual, expected))

class MyAssertTest(MyAssert):
    def testAssertGreaterThan(self):
        self.assertGreaterThan(5, 10)
