Компиляция тестов JUnit во время выполнения: «Нет методов runnable»

Question

Я хочу скомпилировать и запустить тесты JUnit (4.12) во время выполнения проекта grails (2.4.4).

Следующая строка является примером для такого теста (имя класса: «DasS»).

import org.junit.runner.JUnitCore; 
import static org.junit.Assert.*; 
import org.junit.Before;import org.junit.Test; 
import org.junit.After; 

public class DasS { 

    public DasS(){} 

    @Before 
    public void setUp() {} 

    @After 
    public void tearDown(){} 

    @Test 
    public void test0() { 
    assertEquals(new Integer(1),new Integer(1)); 
    } 

    @Test 
    public void test1() { 
    assertEquals(new Double(1),new Double(1)); 
    } 
} 

Целью следующего метода является загрузка в классы и запуск скомпилированных тестов.

public void run() { 

    URLClassLoader loader = (URLClassLoader) getClass().getClassLoader(); 
    DynamicClassLoader dynamicLoader = new DynamicClassLoader(loader); 


    try { 
     dynamicLoader.addURL(new File(Configure.TMP_FOLDER).toURI().toURL()); 
    } catch (MalformedURLException e1) { 
     //Add good exception handling here 
    } 

    try { 
     dynamicLoader.loadClass("DasS"); 
    } catch (ClassNotFoundException e2) { 
     // TODO Auto-generated catch block 
     e2.printStackTrace(); 
    } 
    Class testClass2 = null; 
    try { 
     testClass2 = Class.forName("DasS", true, dynamicLoader); 
    } catch (ClassNotFoundException e2) { 
     // TODO Auto-generated catch block 
     e2.printStackTrace(); 
    } 
    Result result2 = JUnitCore.runClasses(testClass2); 
    for(Failure f : result2.getFailures()) { 
     System.out.println(f.getMessage()); 
    } 

} 

Там нет никаких ошибок во время компиляции, ни во время загрузки классов, но каждый раз, когда я запускаю этот код я не получаю «Нет готовые к выполнению методов» как сообщение об ошибке, хотя, очевидно, есть некоторый тест-метода.

Answer 1

Если я просто скопировать и вставить свой тестовый класс (Дас) в новый класс в Android Studio (путь должен быть правильным), то 2 испытания запуска успешно для меня. Тест бегун выбирается на интерфейсе является:

android.support.test.runner.AndroidJUnitRunner 

мне не нужен вам помощник метод (общественного недействительными запуска())

Зависимости в вашем проекте могут быть разными. Вам может понадобиться подмножество шахты:

dependencies { 
    compile 'com.android.support:support-annotations:22.2.0' 
    androidTestCompile 'com.google.dexmaker:dexmaker:1.2' 
    androidTestCompile 'com.android.support.test:runner:0.4.1' 
    androidTestCompile 'com.android.support.test:rules:0.3' 
    androidTestCompile 'junit:junit:4.12' 
} 

Но вы, возможно, потребуется установить правильный тест бегун (все еще в build.gradle):

defaultConfig { 
    minSdkVersion 19 
    targetSdkVersion 22 
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" 
}
