Robotium script encapsulated as APK, to achieve out-of-phone data cable, use the button to control the operation of the use of small functions

Recently has been completed some robotium small function, for more convenient to complete a number of small functions of the test, or can be said to be used for entertainment, kidnap group inside the Great God ideas, this extension, and finally to realize this function

---------------encapsulate the Robotium script as an apk and use the button to control how much coverage the use case runs, and the test results are entered into the phone's SD card directory with a simple XML file----------------------

Don't say much nonsense, positive questions:

First, make it clear that this article is implemented without exception to the Robotium script you write

Second, clarify the idea:

1. We need a well-functioning, logical Robotium project

2. We need a way to save the results of a script use case to a local

3. We need an activity, a button, and a button click event to run our Robotium script

Third, first introduce the function of the script use case running results, we all know that the Robotium use case is dependent on junit instrumentation, so, about the output of the result, we need to rewrite the Instrumentationtestrunner class

After rewriting the Instrumentationtestrunner class, you need to set the run configurations under our test project, right--move to run As-run configurations-android JUnit on your test project Test, change your project run instrumentation Runner, if not changed, default is Android.test.InstrumentationTestRunner

The position of the red box body circled needs to be changed to the Instrumentationtestrunner path you rewritten

After completing the above steps, you can then run the Robotium script, which will generate a file named Test-all.xml in the folder named Robotium under your phone's root directory to record the results of your script running as follows:

Run normal results, will show the run time, run the error of the use case, will print error message, as for the error message in the Chinese hint, is my use case to add the assertion, you can discretion

Complete this step and you can implement our package APK program. Package apk, first, we need an activity

The interface is relatively down, will look. For the creation and declaration of activity, please do your own Baidu

One or more buttons can be placed in the activity, since Robotium can be run using the command line, so we can use the OnClick event of different buttons to execute different scripts

As above: Attach various command-line startup commands:

Run All test Cases:

ADB shell am instrument-w packagename/instrumentationtestrunnername

Run a single test class or a testsuite
ADB shell am INSTRUMENT-E class packagename.testclassname-w Packagename/instrumentationtestrunnername

Run a test method inside a test class
ADB shell am INSTRUMENT-E class package name. Test Class Name # Method name-W project name. Package name/instrumentationtestrunner class name

Note: Before you write your code, test the command you are using in CMD to run correctly

After completing the above steps, we can package the entire test project as an APK file, remember the signature needs to sign the debug signature, then ... Install it on your phone, unplug the damn data cable, click the button, and start abusing your phone:)
