I\'m trying to mock the SecurityManager class. When I run the following code, Mockito throws an exception:

@After
public void tearDown()
{

    When you change the SecurityManager, you should reset it to the original SecurityManager after the test.

    You may use the System Rules library for your test. Setting and resetting the security manager are just two lines of code with this rule.

    @Rule
    public ProvideSecurityManager provideSecurityManager
      = new ProvideSecurityManager(yourSecurityManager);
    

    Within your test yourSecurityManager is used and outside of the test the original security manager is used.
