扩展InstrumentationTestRunner，传递自定义参数

通过继承InstrumentationTestRunner，就可以传递自定义参数到TestRunner。这里是传递port、packageName、activityName，其中port是用于在手机侧启动一个TCP服务的端口，packageName和activityName是用于指定首个启动的activity的参数配置：

1. import android.os.Bundle;
2. import android.test.InstrumentationTestRunner;
3. public class AthrunInstrumentationTestRunner extends InstrumentationTestRunner {
4. private static String packageName = "com.taobao.fario";
5. private static String activityName = "com.taobao.fario.MainActivity";
6. private static String port = "1234";
7. public static String getPort() {
8. return port;
9. }
10. public static String getPackageName() {
11. return packageName;
12. }
13. public static String getActivityName() {
14. return activityName;
15. }
16. @Override
17. public void onCreate(Bundle arguments) {
18. if (arguments != null) {
19. String port = arguments.getString("port");
20. String packageName = arguments.getString("packageName");
21. String activityName = arguments.getString("activityName");
22. if (port != null) {
23. AthrunInstrumentationTestRunner.port = port;
24. }
25. if (packageName != null) {
26. AthrunInstrumentationTestRunner.packageName = packageName;
27. }
28. if (activityName != null) {
29. AthrunInstrumentationTestRunner.activityName = activityName;
30. }
31. }
32. super.onCreate(arguments);
33. }

执行命令变成：

1. adb -s SH14MTJ01900 shell am instrument -w -e port 1234 -e class org.athrun.remoterunner.TravelTest#test org.athrun.remoterunner/org.athrun.instrumentation.AthrunInstrumentationTestRunner

在Testcase中如何使用传入的packageName和activityName：

1. public class TravelTest extends ActivityInstrumentationTestCase2 {
2. private static String getPkgName() {
3. String packageName = AthrunInstrumentationTestRunner.getPackageName();
4. return packageName;
5. }
6. private static String getActivityClassStr() throws ClassNotFoundException {
7. String activityName = AthrunInstrumentationTestRunner.getActivityName();
8. return activityName;
9. }
10. public TravelTest() throws Exception {
11. super(getPkgName(), getActivityClassStr());
12. }

-e 是属于扩展参数，使用这种方法是可以不断扩展的。
