基本上,我正在尝试创建一个将在具有SQLite 功能的Android 应用程序中使用的JAR 文件,因此我可以将这个JAR 文件用于许多应用程序。
我从头开始创建了一个更小的应用程序,更容易修复错误。这是目录结构,只有三个文件:
testSQLite/build.gradle
testSQLite/src/main/java/com/example/sqltest/SnapzAndroidDB.java
testSQLite/src/test/groovy/SnapzClientTest.groovy
build.gradle
apply plugin: 'java'
apply plugin: 'groovy'

}
}
dependencies {

def 'Create an SQLite database for Android'() {
setup:
def androidDB = new SnapzAndroidDB(Robolectric.application)
expect:

}
我仍然遇到的错误如下:
com.example.DataAccess.SnapClientTest > Create an SQLite database for Android FAILED
java.lang.RuntimeException: Stub!

8 月 4 日编辑 ====================
这是我更新的测试规范,它使用 Robolectric 生成可在 SQLiteOpenHelper(...) 的构造函数中使用的上下文
import org.robolectric.Robolectric
def 'Create an SQLite database for Android'() {
setup:
def androidDB = new SnapzAndroidDB(Robolectric.application)
expect:
androidDB != null
}
我实际测试的函数是一个扩展SQLiteOpenHelper 的类。而我的构造函数SnapzAndroidDB(...) 调用SQLiteOpenHelper() 构造函数,你可以看到上下文是从测试规范传递的第一个参数:
public class SnapzAndroidDB extends SQLiteOpenHelper
public SnapzAndroidDB(Context context) {
super(context, SnapzContract.DB_NAME, null, SnapzContract.DB_VERSION);
}
.
.
}
当我运行我的测试时,我得到了这个错误:
com.sunsystem.HttpSnapClient.SnapClientTest > Create an SQLite database for Android FAILED
java.lang.RuntimeException: Stub!
at android.database.sqlite.SQLiteOpenHelper.<init>(SQLiteOpenHelper.java:4)
at com.sunsystem.DataAccess.SnapzAndroidDB.<init>(SnapzAndroidDB.java:33)
at com.sunsystem.HttpSnapClient.SnapClientTest.Create a sqlite database for Android(SnapClientTest.groovy:168)
结束编辑 ========================
编辑 ====
当我尝试使用 getBaseContext() 时,出现以下错误:
com.sunsystem.HttpSnapClient.SnapClientTest > Create an SQLite database for Android FAILED
groovy.lang.MissingMethodException: No signature of method: com.sunsystem.HttpSnapClient.SnapClientTest.getBaseContext() is applicable for argument types: () values: []
at com.sunsystem.HttpSnapClient.SnapClientTest.Create a sqlite database for Android(SnapClientTest.groovy:159)
我的规范 spock 函数是这样的:
def 'Create an SQLite database for Android'() {
setup:
def androidDB = new SnapzAndroidDB(getBaseContext())
expect:
androidDB != null
}
以下是依赖项:
dependencies {
compile "com.googlecode.json-simple:json-simple:1.1.1", {
// Exclude junit as we don't want this include in our JAR file as it will add hamcast and other dependencies as well
exclude group:'junit', module: 'junit'
}
// Just compile so we can use the SQLite API. This won't be included in the JAR
compile 'com.google.android:android:4.1.1.4', {
// Do not bring in dependencies
transitive = false
}
// Compile for unit testing only
testCompile "org.codehaus.groovy:groovy:2.3.4"
testCompile "org.spockframework:spock-core:0.7-groovy-2.0"
testCompile 'org.robospock:robospock:0.5.0'
testCompile 'com.google.android:android-test:4.1.1.4'
testCompile 'com.android.tools.build:gradle:0.12.2'
testCompile 'org.robospock:robospock-plugin:0.4.0'
}
====
我正在为我用 Java 编写的库进行 Spock 单元测试,该库将在我的 Android 应用程序中使用。
将部署到 Android 应用程序以执行数据库操作的 Java JAR 文件。我正在测试的就是这个 JAR 文件。
我已经编写了一个 Spock 规范来测试 SQLite 数据库的创建。
在我的 Java JAR 文件中,我有一个创建 SQLite 数据库的类,我想在我的 Spock 单元测试中对其进行测试。
但是,问题在于 SQLiteOpenHelper 构造函数需要使用 Context 调用,而我正在尝试在 Spock 单元测试中使用 import android.text.mock.MockContext 模拟该上下文。
public class SnapzAndroidDB extends SQLiteOpenHelper implements SnapzDAO {
public SnapzAndroidDB(Context context) {
super(context, SnapzContract.DB_NAME, null, SnapzContract.DB_VERSION);
}
/* Called only once first time the database is created */
@Override
public void onCreate(SQLiteDatabase db) {
String sqlCreate = String.format("create table %s (%s int primary key, %s text, %s text, %s text)",
SnapzContract.TABLE,
SnapzContract.GetConfigColumn.ID,
SnapzContract.GetConfigColumn.NAME,
SnapzContract.GetConfigColumn.VALUE,
SnapzContract.GetConfigColumn.CFG_TYPE);
db.execSQL(sqlCreate);
}
.
.
}
现在在我的单元测试规范中,我的 SnapClientTest.groovy 中有这个:
import android.test.mock.MockContext
def 'Create an SQLite database for Android'() {
setup:
def context = new MockContext()
def androidDB = new SnapzAndroidDB(context.getApplicationContext())
expect:
androidDB != null
}
从这里你可以看到我正在模拟上下文并将其作为参数发送到我的类的构造函数,该构造函数将调用 SQLiteOpenHelper 构造函数。
我在运行单元测试时遇到的错误是这样的:
com.HttpSnapClient.SnapClientTest > Create an SQLite database for Android FAILED
11:05:27.062 [DEBUG] [TestEventLogger] java.lang.RuntimeException: Stub!
11:05:27.063 [DEBUG] [TestEventLogger] at android.content.Context.<init>(Context.java:4)
11:05:27.063 [DEBUG] [TestEventLogger] at android.test.mock.MockContext.<init>(MockContext.java:5)
11:05:27.063 [DEBUG] [TestEventLogger] at com.sunsystem.HttpSnapClient.SnapClientTest.Create a sqlite database for Android(SnapClientTest.groovy:155)
11:05:27.065 [QUIET] [system.out] 11:05:27.064 [DEBUG] [org.gradle.process.internal.child.ActionExecutionWorker] Stopping client connection.
作为 Spock 的新手,我不确定这是否可行,因为我只是在测试我的 JAR 文件。
【问题讨论】:
-
使用 Robolectric.application 作为上下文是否解决了问题?
-
我更新了我的答案,你应该使用 RoboSpecification 而不是 Specification。
