SpringBootTestでPowerMockRunnerを使用できない

私のプロジェクトでは、SpringBootTestを使用して統合テストを記述しようとしています。サードパーティの静的な最終クラスがあります。パワーモックでモックしてみました。しかし、@ SpringBootTestを使用しようとすると、例外がスローされます。

これが私のサンプルコードです

@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);
   }
 ..
}

構成：

@Configuration
@EnableAutoConfiguration
@ComponentScan("com.xx.yy.zz")

public class SpringTestConfig
{
}

スローされた例外：

ここで何が欠けていますか？ SpringBootのバグですか？

回避策： SpringApplicationConfigurationを使用するための回避策を見つけましたが、このクラスはSpringBootTestで非推奨になりました。だから快適に使えません。

@RunWith(PowerMockRunner.class)
@SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT)
@SpringApplicationConfiguration(classes = SpringTestConfig.class)
@PowerMockRunnerDelegate(SpringRunner.class)
@PrepareForTest(IdGenerator.class)

public class RestTestIT
{

「@SpringBootTest」とPowermockを使用して最終クラスをモックする際に同様の問題が発生しました。以下を使用して修正しました。 SpringTestConfigクラスは次のようになります。

@ContextConfiguration
public class SpringTestConfig
{

}

そして、RestTestITクラスは以下のようになります。

@RunWith(PowerMockRunner.class)
@SpringBootTest(webEnvironment = WebEnvironment.MOCK,classes = SpringTestConfig.class)
@PowerMockRunnerDelegate(SpringRunner.class)
@PrepareForTest(IdGenerator.class)
public class RestTestIT {

}

これらのいずれかを機能させることができませんでしたJava 12、SpringBoot 2.1.7、PowerMock 2.0.0を実行していますが、コンパイルするために以下を取得しました

@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 ....
}

以下の構成セットは私のために働きました：

SpringBootバージョン：

_<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>

       <version>2.0.4</version>
       <scope>test</scope>
    </dependency>
 </dependencies>

以下の条件に従ってコードを変更します。

  • Springブートテストクラスがすでに@RunWith(SpringRunner.class)を使用している場合は、@RunWith(PowerMockRunner.class)に置き換えます。
  • 注釈@PowerMockRunnerDelegate(SpringRunner.class)を使用して、PowerモックをSpringRunner.classにデリゲートさせます
  • 上記のJordan Shawが示唆しているように、クラスを除外するには_@PowerMockIgnore_を使用します
  • @PrepareForTest({<YourClass.class>})を使用して、静的メソッドをモックするクラスをセットアップします
