我有一个使用Spring Security配置的类，我想在它上面写一个单元测试。

@AllArgsConstructor
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

    private AuthenticationManager authenticationManager;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .authorizeRequests(arc -> arc
                        .antMatchers("/**").authenticated()
                )
                .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
                .and()
                .csrf(AbstractHttpConfigurer::disable)
                .oauth2ResourceServer(rsc ->
                        rsc.opaqueToken(
                                (OAuth2ResourceServerConfigurer<HttpSecurity>.OpaqueTokenConfigurer configurer) ->
                                        configurer.authenticationManager(authenticationManager)
                        )
                );
    }
}

我尝试使用Mockito编写单元测试

@ExtendWith(MockitoExtension.class)
class SecurityConfigurationTest {

    @Mock private HttpSecurity httpSecurity;
    @Mock private SessionManagementConfigurer<HttpSecurity> sessionManagementConfigurer;

    @InjectMocks
    private SecurityConfiguration securityConfiguration;

    @Test
    void testConfigure() throws Exception {
        when(httpSecurity.authorizeRequests(any(Customizer.class))).thenReturn(httpSecurity);
        when(httpSecurity.sessionManagement()).thenReturn(sessionManagementConfigurer);
        when(sessionManagementConfigurer.sessionCreationPolicy(SessionCreationPolicy.STATELESS))
                .thenReturn(sessionManagementConfigurer);
        when(sessionManagementConfigurer.and()).thenReturn(httpSecurity);
        when(httpSecurity.csrf(any(Customizer.class))).thenReturn(httpSecurity);
        when(httpSecurity.oauth2ResourceServer(any(Customizer.class))).thenReturn(httpSecurity);

        securityConfiguration.configure(httpSecurity);

        verify(httpSecurity, times(1)).authorizeRequests(any(Customizer.class));
        verify(httpSecurity, times(1)).sessionManagement();
        verify(sessionManagementConfigurer, times(1))
                .sessionCreationPolicy(SessionCreationPolicy.STATELESS);
        verify(sessionManagementConfigurer, times(1)).and();
        verify(httpSecurity, times(1)).csrf(any(Customizer.class));
        verify(httpSecurity, times(1)).oauth2ResourceServer(any(Customizer.class));
    }
}

但是，当我运行单元测试时，我发现并没有覆盖所有代码行：

如何获得100%的覆盖率？
