com.almworks.sqlite4java.SQLiteException：在Android Studio中使用Robolectric运行数据库测试时，不会出现此类表错误

编程问答 2022-06-11

问题描述

我有一个可以在移动设备上运行且没有此数据库错误的应用程序，但是我试图在不使用移动设备的情况下添加测试以用于将来的版本...

我在运行功能数据库测试时遇到此错误，这是我的测试代码：

import android.content.Context
import android.database.sqlite.SQLiteDatabase
import androidx.test.core.app.ApplicationProvider
import com.systango.myApp.auxiliares.DBSQLiteHelper
import com.systango.myApp.modelo.Libro
import org.junit.After
import org.junit.Assert.assertEquals
import org.junit.Before
import org.junit.Test
import org.junit.runner.RunWith
import org.robolectric.RobolectricTestRunner
import java.io.IOException

/**
 * Example local unit test,which will execute on the development machine (host).
 *
 * See [testing documentation](http://d.android.com/tools/testing).
 */
@RunWith(RobolectricTestRunner::class)
class ExampleUnitTest {
    private lateinit var db: SQLiteDatabase

    @Before
    fun createDB() {
        val context = ApplicationProvider.getApplicationContext<Context>()
        val sqLiteHelper = DBSQLiteHelper(context)
        db = sqLiteHelper.readableDatabase
    }

    @After
    @Throws(IOException::class)
    fun closeDb() {
        db.close()
    }

    @Test
    fun addition_isCorrect() {
        assertEquals(4,2 + 2)
    }

    @Test
    fun obt_ok() {
        val libro = getLibro("2")
        assertEquals(1,1)
    }

    private fun getLibro(idLibro: String?): Libro {
        val table = "TBL_LIBROS"
        val columnsToReturn = arrayOf("ID_LIBRO","LIBRO","ABREVIATURA")
        val selection = "id_libro = ?"
        val dbCursor = db.query(table,columnsToReturn,selection,arrayOf(idLibro),null,null)
        val libro = Libro()
        if(dbCursor.moveToFirst()){
            libro.idLibro = dbCursor.getString(0)
            libro.libro = dbCursor.getString(1)
            libro.abrev = dbCursor.getString(2)
        }
        dbCursor.close()

        return libro
    }
}

和错误日志：
