正确的方法来与Robotium和黄瓜截图 [英] Correct way to take screenshot with Robotium and Cucumber

问题描述

使用 Robotium 和 Cucumber ，当一个方案失败时，采用屏幕截图的最佳方法是什么？

Which is the best way to take a screenshot when one scenario fails using Robotium and Cucumber?

我试过了（没有成功，因为它不执行 runTest 方法）：

I have tried (without success, because it doesn't execute runTest method) with this:

import cucumber.api.CucumberOptions;
import cucumber.api.java.After;
import cucumber.api.java.Before;

@CucumberOptions(features = "features", tags = {"~@ignore"})
public class CustomInstrumentationTestCase extends ActivityInstrumentationTestCase2<LaunchActivity> {

    protected Solo solo;

    public CustomInstrumentationTestCase() {
        super(LaunchActivity.class);
    }

    @Before
    public void before() throws Exception {
        //...
    }

    @After
    public void after() throws Exception {
        //...
    }

    @Override
    protected void runTest() throws Throwable {
        try {
            super.runTest();
        } catch (Throwable t) {
            final String testCaseName = String.format("%s.%s", getClass().getName(), getName());
            solo.takeScreenshot(testCaseName);
            Log.w("Boom! Screenshot!", String.format("Captured screenshot for failed test: %s", testCaseName));

            throw t;
        }
    }
}

在清单中：

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

推荐答案

runTest（）方法用于捕获错误和失败，并作为结果进行截图。

Your testclass seems fine. The runTest() methode is used to catch errors and failures and as a result make a screenshot.

对您的类只需添加一个测试如下：

To your class simply add a test like this:

public void testFailsForScreenShot(){
    fail();
}

比运行测试，你会发现一个截图。

Than run the test and you will find a screenshot.

编辑：测试截图：

import android.util.Log;
import com.robotium.solo.Solo;

public class TestScreenshot extends     ActivityInstrumentationTestCase2<LauncherActivity> {

private Solo solo;

public TestScreenshot(){
    super(LauncherActivity.class);
}

@Override
protected void setUp() throws Exception {
    super.setUp();
    solo = new Solo(getInstrumentation(), getActivity());
}

//Test if "Test" fails and takes Screenshot
public void testFailForScreenshot(){
    fail();
}


@Override
public void runTest() throws Throwable {
    try {
        super.runTest();
    } catch (Throwable t) {
        String testCaseName = String.format("%s.%s", getClass().getName(), getName());
        solo.takeScreenshot(testCaseName);
        Log.w("Screenshot taken.", String.format("Captured screenshot for failed test: %s", testCaseName));

        throw t;
    }
}
