我试图掩盖看起来像是

protected SessionBuilderConfigurer getSessionBuilderConfigurer() {
    return cqlSessionBuilder -> {
        ProgrammaticDriverConfigLoaderBuilder programmaticDriverConfigLoaderBuilder;
   
        programmaticDriverConfigLoaderBuilder = getCassandraWithoutSslConfiguration();//Local method

        DriverConfigLoader driverConfigLoader = programmaticDriverConfigLoaderBuilder.build();
        return cqlSessionBuilder
            .withConfigLoader(driverConfigLoader)
            .withAuthCredentials(properties.getUsername(), properties.getPassword());
    };
  }

字符串
这在JUnit中根本没有涉及。
JUnit：

//Class level
@ExtendWith(MockitoExtension.class)

@InjectMocks WaausCassandraConfiguration configuration;

//Inside method
Assertions.assertNotNull(configuration.getSessionBuilderConfigurer());

型

getSessionBuilderConfigurer()创建了一个SessionBuilderConfigurer对象，lambda是某个方法（可能是SessionBuilderConfigurer.configure()）的实现。
如果你想在lambda中执行代码，你需要执行那个方法：

CqlSessionBuilder sessionBuilder = mock(CqlSessionBuilder.class);
// the following line create the SessionBuilderConfigurer
SessionBuilderConfigurer configurer = configuration.getSessionBuilderConfigurer();
// the following line calls the lambda
configurer.configure(sessionBuilder);

// now you need to assert that the correct methods on the sessionBuilder have been called
