SpringMock测试总结

1.常用注解

@Before：初始化方法，在任何一个测试方法执行之前，必须执行的代码。

@After： 释放资源，在任何一个测试方法执行之后，需要进行的收尾工作。

@Ignore：忽略的测试方法，标注的含义就是“某些方法尚未完成，咱不参与此次测试”；这样的话测试结果就会提示你有几个测试被忽略，而不是失败

@BeforeClass：针对所有测试，也就是整个测试类中，在所有测试方法执行前，都会先执行由它注解的方法，而且只执行一次。当然，需要注意的是，修饰符必须是public static void xxxx ；此 Annotation 是 JUnit 4 新增的功能。

@AfterClass：针对所有测试，也就是整个测试类中，在所有测试方法都执行完之后，才会执行由它注解的方法，而且只执行一次。需要注意的是，修饰符也必须是 public static void xxxx ； JUnit 4 新增的功能，与 @BeforeClass 是一对。

执行顺序：

3.对特殊框架的测试mock

3.1 针对shiro模拟用户登录进行mock

在某些场景下，对于shiro用户登录后产生的用户信息，需要用到

shiro官方文档提供了一个测试工具类AbstractShiroTest，需要用到

public abstract class AbstractShiroTest {

    private static ThreadState subjectThreadState;

    public AbstractShiroTest() {
    }

    /**
     * Allows subclasses to set the currently executing {@link Subject} instance.
     *
     * @param subject the Subject instance
     */
    protected void setSubject(Subject subject) {
        clearSubject();
        subjectThreadState = createThreadState(subject);
        subjectThreadState.bind();
    }

    protected Subject getSubject() {
        return SecurityUtils.getSubject();
    }

    protected ThreadState createThreadState(Subject subject) {
        return new SubjectThreadState(subject);
    }

    /**
     * Clears Shiro's thread state, ensuring the thread remains clean for future test execution.
     */
    protected void clearSubject() {
        doClearSubject();
    }

    private static void doClearSubject() {
        if (subjectThreadState != null) {
            subjectThreadState.clear();
            subjectThreadState = null;
        }
    }

    protected static void setSecurityManager(SecurityManager securityManager) {
        SecurityUtils.setSecurityManager(securityManager);
    }

    protected static SecurityManager getSecurityManager() {
        return SecurityUtils.getSecurityManager();
    }

    @AfterClass
    public static void tearDownShiro() {
        doClearSubject();
        try {
            SecurityManager securityManager = getSecurityManager();
            LifecycleUtils.destroy(securityManager);
        } catch (UnavailableSecurityManagerException e) {
            //we don't care about this when cleaning up the test environment
            //(for example, maybe the subclass is a unit test and it didn't
            // need a SecurityManager instance because it was using only
            // mock Subject instances)
        }
        setSecurityManager(null);
    }
}
