java单元测试常用

基本验证输出 Assert.assertEquals(testMethod(),actrueRet)
验证是否可以抛出预期的异常：加注解@Test(expected = InputException.class)
当被测试方法中含有Scanner时，使用：
//输出值测试 @Test public void testOutputData() throws InputException { YangHuiTriangle yangHuiTriangle = new YangHuiTriangle(); String inputData = "7 5"; InputStream stdin = System.in; try { System.setIn(new ByteArrayInputStream(inputData.getBytes())); int data = yangHuiTriangle.outputData(); System.out.println("根据输入行列获取到的数据为："+data); } finally { System.setIn(stdin); } } //被测代码public int outputData() throws InputException { Scanner input = new Scanner(System.in); int m = input.nextInt(); int n = input.nextInt(); return getYHData(m, n); }
