Android studiounit testing：为volley请求编写模拟测试的问题（以非零退出值1结束）
我一直在努力编写针对齐射自定义请求的测试用例，引用我已经从这里实现了FakeHttpStack类和FakeRequestQueue
我的项目测试类结构如下：
/app /src /test /java/package/myClassTest.java /resources/testfile.txt
Gradle file ：
android { compileSdkVersion 23 buildToolsVersion "23.0.1" defaultConfig { minSdkVersion 17 targetSdkVersion 23 // Enabling multidex support. multiDexEnabled true } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt' } } } repositories { maven { url = "https://oss.sonatype.org/content/repositories/snapshots" } jcenter() } dependencies { compile project(':datetimepickerlibrary') compile 'com.google.code.gson:gson:2.2.4' compile 'com.google.android.gms:play-services:+' compile 'com.android.support:appcompat-v7:23.0.1' compile files('libs/android-support-v7-recyclerview.jar') compile files('libs/ksoap2.jar') compile files('libs/nineoldandroids-2.4.0.jar') compile files('libs/volley.jar') compile 'com.android.support:design:23.0.1' testCompile 'junit:junit:4.12' testCompile 'org.robolectric:robolectric:3.0' testCompile 'org.robolectric:shadows-support-v4:3.0' testCompile 'org.robolectric:shadows-httpclient:3.0' testCompile 'org.robolectric:shadows-maps:3.0' testCompile 'org.mockito:mockito-core:1.+' compile 'com.google.guava:guava:16.0.1' } task copyResDirectoryToClasses(type: Copy){ from "${projectDir}/src/test/res" into "${buildDir}/intermediates/classes/test/debug/res" } assembleDebug.dependsOn(copyResDirectoryToClasses)
我的课程如下：
FakeHttpStack.java
import android.content.Context; import com.android.volley.AuthFailureError; import com.android.volley.Request; import com.android.volley.toolbox.HttpStack; import com.android.volley.toolbox.StringRequest; import com.google.common.base.Charsets; import com.google.common.collect.Lists; import com.google.common.io.CharStreams; import org.apache.http.Header; import org.apache.http.HttpEntity; import org.apache.http.HttpResponse; import org.apache.http.HttpVersion; import org.apache.http.entity.StringEntity; import org.apache.http.message.BasicHeader; import org.apache.http.message.BasicHttpResponse; import org.apache.http.message.BasicStatusLine; import java.io.File; import java.io.IOException; import java.io.InputStream; import java.io.InputStreamReader; import java.io.UnsupportedEncodingException; import java.net.URL; import java.text.DateFormat; import java.text.SimpleDateFormat; import java.util.Date; import java.util.List; import java.util.Map; public class FakeHttpStack implements HttpStack { private static final int SIMULATED_DELAY_MS = 500; private final Context context; FakeHttpStack(Context context) { this.context = context; } @Override public HttpResponse performRequest(Request request, Map stringStringMap) throws IOException, AuthFailureError { try { Thread.sleep(SIMULATED_DELAY_MS); } catch (InterruptedException e) {} HttpResponse response = new BasicHttpResponse(new BasicStatusLine(HttpVersion.HTTP_1_1, 200, "OK")); Listheaders = defaultHeaders(); response.setHeaders(headers.toArray(new Header[0])); //response.setLocale(Locale.JAPAN); response.setEntity(createEntity(request)); return response; } private List defaultHeaders() { DateFormat dateFormat = new SimpleDateFormat("EEE, dd mmm yyyy HH:mm:ss zzz"); return Lists. newArrayList( new BasicHeader("Date", dateFormat.format(new Date())), new BasicHeader("Server", /* To use the appropriate server information that came back from Sakura server */ "Apache/1.3.42 (Unix) mod_ssl/2.8.31 OpenSSL/0.9.8e") ); } private HttpEntity createEntity(Request request) throws UnsupportedEncodingException { File file = getFileFromPath(this, "res/testfile.txt"); String resourceName = file.toString(); System.out.println("resourceName found " +resourceName); if (!file.exists()) { System.out.println("No fake file named " + resourceName + " default fake response should be used."); } else { System.out.println("resourceName found " +file.getName()); try { InputStream stream = context.openFileInput(resourceName); String string = CharStreams.toString(new InputStreamReader(stream, Charsets.UTF_8)); if ("randomInt".equals(string)) { string = Integer.toString((int) (Math.random() * Integer.MAX_VALUE)); } return new StringEntity(string); } catch (IOException e) { System.out.println("error reading " + resourceName + e); } } // Since there is no appropriate resources, it returns appropriately if (request instanceof StringRequest) { return new StringEntity("100"); } return new StringEntity(" {\"a\":1,\"b\":2,\"c\":3,\"d\":4,\"e\":5}"); } private static File getFileFromPath(Object obj, String fileName) { ClassLoader classLoader = obj.getClass().getClassLoader(); URL resource = classLoader.getResource(fileName); return new File(resource.getPath()); } }
FakeRequestQueue.java
import android.content.Context; import com.android.volley.AuthFailureError; import com.android.volley.Cache; import com.android.volley.Request; import com.android.volley.RequestQueue; import com.android.volley.toolbox.BasicNetwork; import com.android.volley.toolbox.NoCache; public class FakeRequestQueue extends RequestQueue { public FakeRequestQueue (Context context) { super(new NoCache(), new BasicNetwork(new FakeHttpStack(context))); start(); } @Override public void start () { System.out.println("request start"); super.start(); } @Override public void stop () { System.out.println("request stop"); super.stop(); } @Override public Cache getCache () { System.out.println("request start"); return super.getCache(); } @Override public void cancelAll (RequestFilter filter) { System.out.println("Request cancel with filter " + filter); super.cancelAll(filter); } @Override public void cancelAll (Object tag) { System.out.println("Request cancel with tag " + tag); super.cancelAll(tag); } @Override public Request add (Request request) { System.out.println("Note: FakeRequestQueue is used"); System.out.println("New request "+ request.getUrl()+ " is added with priority "+ request.getPriority()); try { if (request.getBody() == null) { System.out.println("body is null"); } else { System.out.println("Body:" + new String(request.getBody())); } } catch (AuthFailureError e) { // cannot do anything } return super.add(request); } }
myClassTest.java
public class OppTestCase { private static FakeRequestQueue fakeRequestQueue; @Before public void setup() { System.out.println("setup "); if (fakeRequestQueue == null) { fakeRequestQueue = new FakeRequestQueue(RuntimeEnvironment.application.getApplicationContext()); } } @Test public void testinglist(){ GsonRequest gsonRequest = new GsonRequest( Request.Method.GET, Constants.STR_URL_LIST, Result.class, null, new Response.Listener() { @Override public void onResponse(OpportunityListResult response) { System.out.println("response:"+response.toString()); } }, new Response.ErrorListener() { @Override public void onErrorResponse(VolleyError volleyError) { assertEquals(volleyError,notNullValue()); } }) }; fakeRequestQueue.add(gsonRequest); }我的问题是运行测试类它总是给我错误
Error:Gradle: Execution failed for task '::dexDebug'. > com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Program Files\Java\jdk1.7.0_21\bin\java.exe'' finished with non-zero exit value 1.
我是Android工作室的新手，编写测试类请指导我出错的地方。
这可能由于许多原因而发生，例如由于没有足够的RAM来构建项目，因此释放足够的内存，如果它不能解决您的问题，那么您可以尝试删除未使用的依赖库并同步您的gradle，您可以参考这里
app level build.gradle
defaultConfig {multiDexEnabled true}
