2. BX_BOXING_IMMEDIATELY_UNBOXEDhtml
double a = 100d; double d = Double.valueOf(a);
Primitive value is boxed and then immediately unboxed.java
非必要的装箱并当即拆箱操做.框架
Intellij 也会给这样的提示:测试
没什么好说的ui
3. IJU_SETUP_NO_SUPERspa
好像是个遗留问题,出如今JUnit3的时代,e.g..net
JUnit3里会这么作code
public class TheTest extends TestCase { // test methods ... public static Test suite() { return new TestSetup(new TestSuite(TheTest.class)) { protected void setUp() throws Exception { super.setUp(); // set-up code called only once } protected void tearDown() throws Exception { // tear-down code called only once super.tearDown(); } };
因此须要这个super.setUp()来初始化
htm
JUnit4开始大规模使用Annotation,咱们有@Before @After来作这些事。blog
固然,如今JUnit4也已经用了不少年了,诸如Spock这样的测试框架也挺好用的~
