三、启用assert 默认情况下,Java的assert是禁用的。要启用assert,需要在运行Java程序时使用-ea(或者-enableassertions)参数。例如: java -ea YourClass 四、使用assert进行单元测试 在Java中进行单元测试时,通常使用JUnit框架。但是,有时候我们可以使用assert来进行简单的测试。下面我们来看一个示例。 五、示例代码 假设...
assertEquals(java.lang.String message, java.lang.Object expected, java.lang.Object actual); 参数message的信息,会在运行结果中打印出来。 将测试类修改如下: publicclassAssertTests{@Testpublicvoidshould_Equals(){StringexpectedResult="him";StringactualResult="she";Assert.assertEquals("2018-05-04",expected...
我们可以使用Mermaid语法绘制一个状态图,表示Assert类的工作流: CreateAssertClassImplementMethodsWriteTestsRunTestsValidateResults 结尾 通过以上步骤,我们实现了一个简单的Java Assert类,掌握了如何创建和测试断言的方法。assert在Java中的使用可以提高代码的可靠性,减少在调试过程中的时间消耗。 希望这篇文章能够帮助初学...
test2使用断言代替if 语句 public class AssertTests { //if else的用法 @Test public void test1() { Object o = null; if (o == null) { throw new IllegalArgumentException("用户不存在."); } } //断言的用法:更为简洁 @Test public void test2() { // 另一种写法 Object o = null; Assert....

It aids the TDD process, in which tests are written before the code, and the code should pass those tests to match the given requirements. It improves the code quality as assertions act as a quality gate. Assertions can help enforce quality gates such as SonarCloud during the deployment proc...
