为什么我的测试运行在同一个分支上？

Question

当我运行进行我的测试时 class 后面的测试使用前面的模拟。我在 Maven 中使用 JMockit。我读到它们可能运行ning 在同一个 jvm 分支上？如果是这种情况，有人可以解释我如何运行他们在不同的分支上吗？如果不是，那么谁能解释为什么会重复使用模拟（从而破坏测试）。

public class ServiceUploadTest {
private String filePath = "src/test/resources/AudioTestFile.mp3";
private ServiceUpload serviceUpload = new ServiceUpload();

@Test
@DisplayName("TestConversionOfMp4ToMp3")
void testConversionOfMp4ToMp3() {

    new MockUp<Encoder>() {
        @Mock
        public void encode(MultimediaObject multimediaObject, File target, EncodingAttributes attributes) throws IllegalArgumentException, InputFormatException, EncoderException {
        }
    };
    assertEquals("src/test/resources/Audio.mp3", serviceUpload.convertToMp3(filePath));
}

@Test
@DisplayName("Test cutting loop when length is over 5000000")
void testLongCuttingLoop() throws IOException {
    InputStream inputStream = new FileInputStream("/Users/hywelgriffiths/Documents/IntellijProjects/sipho/transcriptionSoftware/audio.transcribe.front/src/test/java/resources/base64.txt");
    BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
    String base64 = bufferedReader.readLine();
    ServiceUpload serviceUpload = new ServiceUpload();

    new MockUp<ProviderUpload>() {
        @Mock
        public String executeUploadHttp(String mp3Base64, String jobName, String tag, String email) {
            return null;
        }
    };

    assertNull(serviceUpload.cuttingLoop(base64, "JOBNAME", null));
}

@Test
@DisplayName("Test cutting loop when length is under 5000000")
void testShortCuttingLoop() throws IOException {
    ServiceUpload serviceUpload = new ServiceUpload();

    new MockUp<ProviderUpload>() {
        @Mock
        public String executeUploadHttp(String mp3Base64, String jobName, String tag, String email) {
            return null;
        }
    };

    assertNull(serviceUpload.cuttingLoop("SHORTBASE64", "JOBNAME", null));
}

@Test
@DisplayName("Test convertToBase64AndSend")
void testConvertToBase64AndSend(){
    ServiceUpload serviceUpload = new ServiceUpload();
    File file = new File ("src/test/java/resources/fakeMp4.txt");
    String jobName = "JOBNAME";

    new MockUp<ServiceUpload>() {
        @Mock
        public String convertToMp3(String mp4File) {
            return "src/test/java/resources/fakeMp4.txt";
        }
    };

    assertNull("\"complete\"", serviceUpload.convertToBase64AndSend(jobName, file, null, false));
}

@Test
@DisplayName("Test convertToBase64andSendCatchBlock")
void testConvertToBase64AndSendCatch(){
    ServiceUpload serviceUpload = new ServiceUpload();
    File file = new File ("src/test/java/resources/fakeMp4.txt");
    String jobName = "JOBNAME";

    new MockUp<ServiceUpload>() {
        @Mock
        public String convertToMp3(String mp4File) throws Exception {
            throw new Exception("Forced Exception");
        }
    };

    assertEquals("\"complete\"", serviceUpload.convertToBase64AndSend(jobName, file, null, false));
}

@Test
@DisplayName("Test convertToMp3 catch block")
void testConvertToMp3CatchBlock() {

    new MockUp<ServiceUpload>() {
        @Mock
        public String createMp3(String mp4file) throws Exception {
            throw new Exception("Forced Exception");
        }
    };

    assertNull(serviceUpload.convertToMp3(filePath));
}
}

注意：

事实证明这是我在 POM 中的依赖项（感谢 Jeff）我正在使用 :

    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.13</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.junit.jupiter</groupId>
        <artifactId>junit-jupiter</artifactId>
        <version>RELEASE</version>

并将其更改为

    <dependency>
        <groupId>org.junit.jupiter</groupId>
        <artifactId>junit-jupiter-params</artifactId>
        <version>5.3.1</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.junit.jupiter</groupId>
        <artifactId>junit-jupiter-engine</artifactId>
        <version>5.3.1</version>
        <scope>test</scope>
    </dependency>

Answer 1

你发生了一些微妙的事情，在你拔头发之前我会检查你的假设。首先，确认 MockUp 在测试之间确实存在泄漏（不应该）。一个简单的方法是在每个 MockUp 中添加一个 System.out.println（也许在 setup/teardown 中），然后当它运行每个测试时，您应该会看到不期望的 printlns。如果你不这样做，那么 JMockIt 的行为就像人们所期望的那样。

假设你的理论是正确的，我会看看 pom.xml 文件。具体来说，万无一失的设置（如果你发布它会很好）。我猜你对 'branches' 的评论确实在 forking/threading/test-parallelization 中得到了解决，surefire 确实如此。您可能在那里遇到了一些小问题，要正确调整它可能很棘手。

我认为您错过了测试顶部的注释 class，请参阅此。
