@H_403_0@使用custom Espresso FailureHandler配置此功能的最佳方法是什么？

解决方法:

@H_403_0@这就是我现在这样做的方式：

@H_403_0@

public class MainScreenTest extends BaseStatelessBlackBoxEspressoTest<LaunchActivity> {    public MainScreentest() {        super(LaunchActivity.class);    }    public voID testMainScreen() {        // Unfortunately this must be explicitly called in each test :-(        setUpFailureHandler();        onVIEw(withID(R.ID.main_circle)).                check(matches(isdisplayed()));    }}

@H_403_0@我的基础Espresso测试类设置自定义FailureHandler(我喜欢使用基类来保存许多其他常用代码)：

@H_403_0@

public abstract class BaseStatelessBlackBoxEspressoTest<T extends Activity> extends BaseBlackBoxTest<T> {    public BaseStatelessBlackBoxEspressoTest(Class clazz) {        super(clazz);    }    @Before    public voID setUp() throws Exception {        super.setUp();        getActivity();    }    public voID setUpFailureHandler() {        // Get the test class and method.  These have to match those of the test        // being run, otherwise the screenshot will not be displayed in the Spoon         // HTML output.  We cannot call this code directly in setUp, because at         // that point the current test method is not yet in the stack.        StackTraceElement[] trace = Thread.currentThread().getStackTrace();        String testClass = trace[3].getClassname();        String testMethod = trace[3].getmethodname();        Espresso.setFailureHandler(new CustomFailureHandler(                getInstrumentation().getTargetContext(),                testClass,                testMethod));    }    private static class CustomFailureHandler implements FailureHandler {        private final FailureHandler mDelegate;        private String mClassname;        private String mMethodname;        public CustomFailureHandler(Context targetContext, String classname, String methodname) {            mDelegate = new DefaultFailureHandler(targetContext);            mClassname = classname;            mMethodname = methodname;        }        @OverrIDe        public voID handle(Throwable error, Matcher<VIEw> vIEwMatcher) {            try {                mDelegate.handle(error, vIEwMatcher);            } catch (Exception e) {                SpoonScreenshotAction.perform("espresso_assertion_Failed", mClassname, mMethodname);                throw e;            }        }    }}

@H_403_0@…这是从the Gist posted by Square略微修改的截图代码：

@H_403_0@

/** * Source: https://github.com/square/spoon/issues/214#issuecomment-81979248 */public final class SpoonScreenshotAction implements VIEwAction {    private final String tag;    private final String testClass;    private final String testMethod;    public SpoonScreenshotAction(String tag, String testClass, String testMethod) {        this.tag = tag;        this.testClass = testClass;        this.testMethod = testMethod;    }    @OverrIDe    public Matcher<VIEw> getConstraints() {        return Matchers.anything();    }    @OverrIDe    public String getDescription() {        return "Taking a screenshot using spoon.";    }    @OverrIDe    public voID perform(UiController uiController, VIEw vIEw) {        Spoon.screenshot(getActivity(vIEw), tag, testClass, testMethod);    }    private static Activity getActivity(VIEw vIEw) {        Context context = vIEw.getContext();        while (!(context instanceof Activity)) {            if (context instanceof Contextwrapper) {                context = ((Contextwrapper) context).getBaseContext();            } else {                throw new IllegalStateException("Got a context of class "                        + context.getClass()                        + " and I don't kNow how to get the Activity from it");            }        }        return (Activity) context;    }        public static voID perform(String tag, String classname, String methodname) {        onVIEw(isRoot()).perform(new SpoonScreenshotAction(tag, classname, methodname));    }}

@H_403_0@我很乐意找到一种避免在每次测试中调用setUpFailureHandler()的方法 – 如果您对如何避免这种情况有一个好主意,请告诉我！
