对于我的项目，我正在尝试使用SpringBootTest编写集成测试。我有第三方静态决赛课。我试着用Power mock嘲笑它。但是当尝试使用@SpringBootTest时，会抛出异常。
这是我的示例代码
NameError配置：
if 'year' in values:
# do something
抛出异常：
@RunWith(PowerMockRunner.class)
@SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT, classes = SpringTestConfig.class
@PowerMockRunnerDelegate(SpringRunner.class)
@PrepareForTest(IdGenerator.class)
public class RestTestIT
{
@Before
public void setUp() throws Exception
{
PowerMockito.mockStatic(IdGenerator.class);
}
..
}
Spring Boot版本：1.4.0.RELEASE
@Configuration
@EnableAutoConfiguration
@ComponentScan("com.xx.yy.zz")
public class SpringTestConfig
{
}
我在这里缺少什么？它是springBoot的错误吗？
解决方法： 我找到了一个使用SpringApplicationConfiguration的解决方法，但是在SpringBootTest中不推荐使用这个类。所以不舒服使用。

我在使用“@SpringBootTest”和Powermock模拟最终类时遇到了类似的问题。我用以下方法修复了你的SpringTestConfig类应该如下所示。
@ContextConfiguration
public class SpringTestConfig
{
}
你的RestTestIT类应如下所示。
@RunWith(PowerMockRunner.class)
@SpringBootTest(webEnvironment = WebEnvironment.MOCK,classes = SpringTestConfig.class)
@PowerMockRunnerDelegate(SpringRunner.class)
@PrepareForTest(IdGenerator.class)
public class RestTestIT {
}

我都无法使用它们，我正在运行Java 12，SpringBoot 2.1.7，PowerMock 2.0.0，但是我确实得到了以下内容进行编译
@SpringBootTest
@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(SpringRunner.class)
@PrepareForTest(FileUtils.class)
@PowerMockIgnore({"com.sun.org.apache.xerces.*", "javax.xml.*", "javax.xml.transform.*", "org.xml.*", "javax.management.*", "javax.net.ssl.*", "com.sun.org.apache.xalan.internal.xsltc.trax.*"})
public class CallControllerTest {
.... tests here ....
}

下面的配置对我有用：
SpringBoot版本：
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.2.3.RELEASE</version>
<relativePath/>
</parent>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
</dependency>
<dependency>
<groupId>org.powermock</groupId>
<artifactId>powermock-module-junit4</artifactId>
<version>2.0.4</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.powermock</groupId>
<artifactId>powermock-api-mockito2</artifactId>
<version>2.0.4</version>
<scope>test</scope>
</dependency>
</dependencies>
根据以下条件更改代码：
@RunWith(SpringRunner.class)，则将其替换为@RunWith(PowerMockRunner.class) @PowerMockRunnerDelegate(SpringRunner.class)将Power模拟委托给SpringRunner.class @PowerMockIgnore排除类@PrepareForTest({<YourClass.class>})设置您的类，该类具有要模拟的静态方法
