無法使用 ant 構建 android 測試項目

[英]Unable to build android test project with ant

我有一個使用 Eclipse 創建的示例 Android 應用程序,有一個 Activity。 我運行這個命令來為這個項目構建 ant 構建文件:

android create project --target 8 --name SampleApp --path ./SampleApp --activity MainActivity --package com.example.sampleapp

運行“ant debug”成功構建項目並創建apk文件:

-post-build:

debug:

BUILD SUCCESSFUL
Total time: 1 second

現在,我想創建一個 Android 測試項目。 我運行這個命令:

android create test-project -m ../SampleApp -n SampleAppTest -p SampleAppTest

這成功創建了包含構建文件的 SampleAppTest 目錄。 我有一個類,src/com/example/sampleapp/MainActivityTest.java:

package com.example.sampleapp;

import android.test.ActivityInstrumentationTestCase2;

public class MainActivityTest extends ActivityInstrumentationTestCase2<MainActivity> {

    public MainActivityTest() {
        super("com.example.sampleapp", MainActivity.class);
    }

}

我想建立這個項目。 http://developer.android.com/tools/testing/testing_otheride.html#RunTestsAnt的教程中,它說我應該能夠進行“螞蟻運行測試”。 不幸的是,這個目標不存在:

$ ant run-tests
Buildfile: /Users/cmuraru/Work/androidtest/SampleAppTest/build.xml

BUILD FAILED
Target "run-tests" does not exist in the project "SampleAppTest". 

Total time: 0 seconds

如果我嘗試“ant debug”,我會在編譯時收到一個錯誤,指出找不到 MainActivity 類(來自 SampleApp)。

-compile:

嘗試“螞蟻測試”時,它也失敗了:

     [echo] Running tests ...
     [exec] INSTRUMENTATION_STATUS: id=ActivityManagerService
     [exec] INSTRUMENTATION_STATUS: Error=Unable to find instrumentation info for: ComponentInfo{com.example.sampleapp.tests/android.test.InstrumentationTestRunner}

我在這里錯過了什么/做錯了什么? 任何幫助都非常感謝。

好的,我發現了問題。 我沒有提到在 ant.properties 中,我已將 out.dir 位置更改為“../build”。 正因為如此,編譯器在構建 SampleAppTest 時不知道從哪里獲取 SampleApp 的類文件。 因此,一種解決方案是刪除 ant.properties 中的 out.dir 條目,但我不想那樣做。 我必須找到一種方法來告訴編譯器從哪里獲取這些類。 我找到的解決方案是像這樣覆蓋 build.xml 中的“-compile”目標:

<property name="SampleApp.build.location" value="../build"/>
    <target name="-compile" depends="-build-setup, -pre-build, -code-gen, -pre-compile">
        <do-only-if-manifest-hasCode elseText="hasCode = false. Skipping...">

            </if>

        </do-only-if-manifest-hasCode>
    </target>

有一種方法可以代替手動更新 ant.properties。 從命令行,運行以下命令:

android update test-project -m <project path> -p <test project path>

運行此命令后,您可以直接從測試項目運行 ant debug。 注意:如果出現 JUnit 相關錯誤,請在測試項目的 libs 文件夾中添加 Junit jar 文件。
