问题描述

我通过Maven设置了一个Android测试项目，并按照此处的说明进行操作. 基本上，我能够设置测试项目，甚至可以识别仿真器，但是执行mvn install(在Eclipse中)时，我仍然无法通过Maven运行测试.如果尝试执行它，则会出现以下错误:

I setup an Android test project by Maven and followed the instructions from here. Basically I was able to setup the test project, even the emulator is being recognized, but I still can't run the tests by Maven when executing mvn install (in Eclipse). If I try to execute it, I get the following errors:

失败的测试:警告(junit.framework.TestSuite $ 1):构​​造函数中的异常:testPersistAndRead(java.lang.RuntimeException:Stub！(..) 警告(junit.framework.TestSuite $ 1):构​​造函数中的异常:testFileNotExists(java.lang.RuntimeException:Stub！(..) 警告(junit.framework.TestSuite $ 1):构​​造函数中的异常:testCreateFiles(java.lang.RuntimeException:Stub！(..) 警告(junit.framework.TestSuite $ 1):构​​造函数中的异常:testFilesExist(java.lang.RuntimeException:Stub！(..) 警告(junit.framework.TestSuite $ 1):构​​造函数中的异常:testAndroidTestCaseSetupProperly(java.lang.RuntimeException:Stub！(..)

surfire的输出告诉我它嵌套在AndroidTestCase中:

The output from surfire tells me that it is nested in AndroidTestCase:

junit.framework.AssertionFailedError:构造函数中的异常:testPersistAndRead(java.lang.RuntimeException:Stub！ 在android.test.AndroidTestCase(AndroidTestCase.java:5) [...]

junit.framework.AssertionFailedError: Exception in constructor: testPersistAndRead (java.lang.RuntimeException: Stub! at android.test.AndroidTestCase.(AndroidTestCase.java:5) [...]

这是我尝试运行的测试.

This is the test I try to run.

public class PersistenceManagerTest extends AndroidTestCase {

    private final String FILENAME_PREFIX = "test.";

    protected void setUp() throws Exception {
        super.setUp();
        deleteInternalStorageFile();

        MockContentResolver resolver = new MockContentResolver();
        RenamingDelegatingContext renamingDelegatingContext = new RenamingDelegatingContext(new MockContext(), getContext(), FILENAME_PREFIX);
        Context context = new IsolatedContext(resolver, renamingDelegatingContext);

        setContext(context);
    }

    //AfterClass
    protected void tearDown() {
        deleteInternalStorageFile();
    }

    public void testPersistAndRead() throws IOException {
        String testData = "foobar";

        PersistenceManager.persist(testData, FileType.JSONDATA);

        String result = PersistenceManager.getFileData(FileType.JSONDATA);

        assertEquals(testData, result);
    }

    public void testFileNotExists()  {
        try {
            PersistenceManager.getFileData(FileType.JSONDATA);
            fail("PersistenceManager.getFileData should throw an exception!");
        } 
        catch (IOException e) {
            //expected
        }
    }

    public void testCreateFiles()  {
        try {
            PersistenceManager.createNewFiles();
        } 
        catch (IOException e) {
            fail("PersistenceManager.createNewFiles() threw an exception");
        }   
        try {
            PersistenceManager.getFileData(FileType.JSONDATA);
        } 
        catch (IOException e) {
            fail("PersistenceManager.getFileData should not throw an exception!");
        }
    }

    public void testFilesExist() throws IOException  {
        assertFalse(PersistenceManager.filesExist());

        PersistenceManager.createNewFiles();

        assertTrue(PersistenceManager.filesExist());
    }

    private void deleteInternalStorageFile() {
        getContext().deleteFile(PersistenceManager.JSONDATAFILE);
        getContext().deleteFile(PersistenceManager.TIMESTAMPFILE);
    }
}

...这是测试项目中的pom.xml.

...and this is the pom.xml from the test project.

有什么想法为什么不起作用?

Any ideas why this isn't working?

推荐答案

我找到了解决方法 dtmilano的回答基本上没有错，但是我不知道这对我的测试意味着什么.解决方案是告诉Maven，不得将测试工具作为JUnit测试运行，因此，测试工具不得在src/test/java中，而应在src/main/java中.相反，必须将它们包含在apk中，以便将它们部署在设备上并触发运行.

dtmilano's answer is basically not wrong, but I didn't know what that means for my test. The solution is to tell Maven that instrumentation tests must not be run as JUnit tests, so the instrumentation tests must not be in src/test/java but in src/main/java. Instead they have to be included into the apk, so they are getting deployed on the device and triggered to run.
