@H_301_1@我有一个Spring Boot应用程序,它有一些配置属性.我正在尝试为某些组件编写测试,并希望从test.properties文件加载配置属性.我无法让它发挥作用.

@H_301_1@这是我的代码：

@H_301_1@test.properties文件(在src / test / resources下)：

@H_301_1@

vehicleSequence.propagationTreeMaxSize=10000

@H_301_1@配置属性类：

@H_301_1@

package com.acme.foo.vehiclesequence.config;

import javax.validation.constraints.NotNull;

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@Component
@ConfigurationProperties(prefix = VehicleSequenceConfigurationProperties.PREFIX)
public class VehicleSequenceConfigurationProperties {
    static final String PREFIX = "vehicleSequence";

    @NotNull
    private Integer propagationTreeMaxSize;

    public Integer getPropagationTreeMaxSize() {
        return propagationTreeMaxSize;
    }

    public void setPropagationTreeMaxSize(Integer propagationTreeMaxSize) {
        this.propagationTreeMaxSize = propagationTreeMaxSize;
    }
}

@H_301_1@我的测试：

@H_301_1@

@RunWith(SpringRunner.class)
@ContextConfiguration(classes = VehicleSequenceConfigurationProperties.class)
@TestPropertySource("/test.properties")
public class VehicleSequenceConfigurationPropertiesTest {

    @Autowired
    private VehicleSequenceConfigurationProperties vehicleSequenceConfigurationProperties;

    @Test
    public void checkPropagationTreeMaxSize() {
        assertThat(vehicleSequenceConfigurationProperties.getPropagationTreeMaxSize()).isEqualTo(10000);
    }
}

@H_301_1@测试失败并显示“Expecting actual not to null”表示未设置配置属性类中的属性propagationTreeMaxSize.

@RunWith(SpringRunner.class)
@TestPropertySource("/test.properties")
@EnableConfigurationProperties(VehicleSequenceConfigurationProperties.class)
public class VehicleSequenceConfigurationPropertiesTest {

    @Autowired
    private VehicleSequenceConfigurationProperties vehicleSequenceConfigurationProperties;

    @Test
    public void checkPropagationTreeMaxSize() {
        assertThat(vehicleSequenceConfigurationProperties.getPropagationTreeMaxSize()).isEqualTo(10000);
    }
}
