SugarORM:在进行仪器测试时，没有这样的表格 [英] SugarORM : While instrumentation testing, No such table Exception

问题描述

这是我的ApplicationTest.java

package com.example.testing;

import android.app.Application;
import android.test.ApplicationTestCase;

import com.example.agent.database.MyGroupsTable;
import com.orm.SugarContext;

import java.util.List;

/**
 * <a href="http://d.android.com/tools/testing/testing_android.html">Testing Fundamentals</a>
 */
public class ApplicationTest extends ApplicationTestCase<Application> {
    static final String DB_NAME = "database.db";

    public ApplicationTest() {
        super(Application.class);
    }

    @Override
    protected void setUp() throws Exception {
        super.setUp();
        boolean deleted = mContext.deleteDatabase(DB_NAME);
        SugarContext.init(mContext);
    }

    /**
     * :Check: tables created or not
     */
    public void testDatabase() {
        int currentapiVersion = android.os.Build.VERSION.SDK_INT;
        if (currentapiVersion >= android.os.Build.VERSION_CODES.LOLLIPOP) {
            MyGroupsTable table = new MyGroupsTable();
            long i = table.save();
            assertTrue("Failed check table", i >= 0);
        } else {
            MyGroupsTable i = MyGroupsTable.findById(MyGroupsTable.class, (long) 0);
            long j = MyGroupsTable.save(new MyGroupsTable("1", "testing", "description", "avatar"));
            assertTrue("Failed to create table", j < 0);
            List<MyGroupsTable> my = MyGroupsTable.find(MyGroupsTable.class, " GROUPID = ?", "1");
            if (my.size() > 0) {
                assertTrue(true);
            } else {
                assertTrue(false);
            }

            assertTrue("Failed to get results from MyGroupsTable", my.get(0).getGroup_id().equals("1"));
        }
    }

}

我正在使用SugarORM.当以调试或发行版本的形式运行应用程序时，这工作正常，但是当我尝试执行Instrumentation测试时，它会因异常而爆炸

I am using SugarORM. Which is working fine when running the app as debug or release but when i tries to execute Instrumentation test it blows up with Exception

这是堆栈跟踪 测试从下午4:36开始...

测试完成.

该代码在Lollipop之前和之后的Lollipop设备上以调试/发行版运行时均能正常工作. 但是我尝试执行仪器测试. 它不会引发此类表异常.

The code is working fine on pre-Lollipop and post Lollipop devices while running as debug/release. But i try to execute Instrumentation Testing. It throws no such Table Exception.

推荐答案

从ref: https://github.com/satyan/sugar/issues/613#issuecomment-223300514

创建一个类:

public class App extends SugarApp {
    @Override
    public void onCreate() {
        super.onCreate();
        SugarContext.init(this);
    }

    @Override
    public void onTerminate() {
        SugarContext.terminate();
        super.onTerminate();
    }
}

然后在AndroidManifest.xml中指定它

Then specify it in AndroidManifest.xml

<application
    ...
    android:name=".App">
    ...
</application>

卸载应用程序，禁用instarun，然后再次运行.它对我有用.

Uninstall app, disable instarun, Then run again.It worked for me.
