I'm writing unit tests for a ListActivity in Android that uses a handler to update a ListAdapter. While my activity works in the Android emulator, running the same code in a unit test doesn't update my adapter: calls to sendEmptyMessage do not call handleMessage in my activity's Handler. How do I get my ActivityUnitTestCase to sync with the MessageQueue thread and call my Handler?

I am queuing up a bunch of runnables into a thread via a Handler.post(). I would like the ability to send a note to that thread that it should pause. By pause I mean, finish the runnable or message you are currently working on, but don't go to the next message or runnable in your message queue until I tell you to continue.

If I were within the main application, I know I could just place the file in the assets directory and use getResources().getAssets().open(sourceFile).However, this API appears to be unavailable from the ActivityInstrumentationTestCase2 class.Is there an easy way to copy a file over from the testing PC, or should I just keep a fresh copy of a test fixture on the device and copy it over a temporary file?

On this page: http: // developer . android . com/ resources / tutorials /testing /hello android. Google writes about a unit test. Is this really a unit test? A Unit test will not integrate all classes and will not test in his context. So my opinion is it is not a Unit Test but an Integration Test.

So one project contains models and logic, then another project contains tests for said library. There is no front end or UI, so I want to do the bare minimum to just be able to test that my methods all work in isolation.
View 1 Replies View RelatedI just switched the way my Android project is being built and non of my unit tests work any more...I get errors like WARN/dalvikvm(575): VFY: unable to resolve static field X in WARN/dalvikvm(575): VFY: unable to find class referenced in signature These errors only come from my Unit Tests, where classes defined in it can't even see other classes defined in the unit test. Before each project had it's own directory with copies of the 3rd party jar files. I've read around that Dex does weird things with references but haven't been able to figure out how to fix this problem. Is there a better way to do this? I would love to see an example of a large Android workspace where there are multiple projects, jar references, etc.Is it possible to fix this with an Order/Export tweak ?

View 3 Replies View RelatedI my main app and tests are organized like this (standard from "android create project"): AndroidManifest.xml assets/ main app asset files src/tests/AndroidManifest.xml -- uses <instrumentation> to point to the main app assets/ -- test-specific asset files src/ Writing test cases with AndroidTestCase, I'd like to load asset files from the test-specific assets/ directory, not from the main app assets/ directory. How can I accomplish that? The normal way to load an asset would be getContext().getAssets().open ("foo.txt"), for assets/foo.txt in the main app. I assume I just have to somehow change the Context or the AssetManager to point to the test- specific assets directory, but I don't see any way to do that. I have looked into the tests/bin/MyApp-debug.apk to confirm that the test assets are in there. Now I just need a way to access them.
View 2 Replies View RelatedI am trying to unit test a class that does SAX parsing and creates an object.This class takes a string as a parameter representing the URL of a document on the internet, parses it and then creates an object based on the contents.I don't want to have the unit tests actually access the network, so I'd like to have a few test xml files to parse. However I can't figure out how to access them from my AndroidTestCases. I don't want to include the test files with the actual application, I want them in the test project (it's a separate project, as is the norm for Android tests from what I could gather - due to the need to have a custom AndroidManifest.xml, for one).One way would be to put the XML files in the test project's assets directory, I can read them using getContext() .getAssets().open(filename) into an InputStream in the test case, but my class expects a URL string. I'd rather not have to provide an InputStream to this class instead of the current URL string. I can test just the parsing by making two methods, one that takes a string and one an Inputstream, and test the second, but how can I then test the one that just takes a string?How should I design my class and or tests to circumvent this problem?
View 1 Replies View RelatedBeing able to write Android apps in regular Java is a huge win. However, I am confused about unit testing Android apps. Many of the 'best practices' seem to boil down to 'split your business logic off, and test it separately using JUnit'. This is great as far as it goes. And I understand that truly testing the UI will require firing up the emulator. But it seems there is a category of UI tests that I should be able to run without the emulator. The various Mockxxx classes seem to be going a long way towards this. But why (oh why oh why!) do they all. throw new RuntimeException( "Stub!" ); in their constructors? I can understand them doing this in their METHODS (then I could subclass them as needed) but why their constructors? I cannot stop this functionality so I cannot do (limited but useful) UI tests such as public TextView createTextView ( Context context ) {return new TextView( context );

I am starting with an Activity based off of this ShakeActivity and I want to write some unit tests for it. I have written some small unit tests for Android activities before but I'm not sure where to start here. I want to feed the accelerometer some different values and test how the activity responds to it. For now I'm keeping it simple and just updating a private int counter variable and a TextView when a "shake" event happens. So my question largely boils down to this: How can I send fake data to the accelerometer from a unit test?
View 3 Replies View RelatedI was curious about the nature of the handleMessage() and sendMessage() behavior of the Handler class. I want to be able to send message to another thread in such a way that the destination thread can process the message queue when it wants to. It seems, however, that the message is processed by handleMessage() practically as soon as it's sent.
I'm trying to design a game loop thread that does something like this:
CODE:.....
However, I as soon as sendMessage() is called (from the parent/calling thread), the Handler.handleMessage() is processed (in the child/receiving thread), even if the child/receiving thread is blocking in a while loop.
I've seen this problem solved in other games by using a thread-safe list (ConcurrentLinkedQueue). The UI thread just posts events to this queue, and the game loop can remove the events as it seems fit. I just assumed the Handler class was designed for this purpose. It seems it's more intended for asynchronous callbacks to the parent thread.
I approached this problem as an oh hey that's not too bad, I can write a bunch of unit tests, and I have been keeping my suite green. However as things get more involved continuous integration and testing is a great great thing to have. And then I saw oh Android has emma integration as well awesome ... and then that's where it get's iffy. So I setup Hudson and have it call the coverage target of the ant build.xml that the android executable in the sdk can generate. And then it hits me. adb -s <emulator> shell am instrument -w ... will never return a result code that is not 0 ... because adb technically exited cleanly and usually will regardless of how the shell command that executed did..............

I want to test parsing of data returned from server.I thought I might create several test XML files and then feed them to the sax parser which uses my custom data handler (as in the application that I test).But where should I put those test XMLs?I tried with [project_root] /res/xml, but then I get the error: android.content.res.Resources $NotFoundException: Resource ID #0x7f040000 type #0x1c is not valid at android.content. res. Resources. loadXml ResourceParser(Resources.java:1870)at android.content.res. Resources. getXml(Resources. java:779) Does that mean that the xml is invalid, or that android couldn't find the XML file?(I use the same XML that comes from the server - copied it from the firebug's net panel and pasted into the file).Can I somehow read that XML as a text file, since etContext(). getResources() .getXml (R.xml.test_response1) returns XmlResourceParser instead of String (which I'd prefer)?

I've looked around in the settings, turned my phone on and off, cleared the data, but still can't get it to revert, it's quite annoying to scroll through hundreds of messages to get to the most recent SMS.

View 1 Replies View RelatedI'm writing an Android app. I have a main method, which creates and runs a new Thread using an anonymous inner Runnable class. The run() method, when it's done, calls a method on it's parent class (in the main thread) that calls notifyDataSetChanged() so that the main thread can redraw the new data. This is causing all kinds of trouble (ViewRoot$CalledFromWrongThreadException). The thing is, this method being called from the worker thread is on the class that's created in the UI thread. Shouldn't that be running on the UI thread? Or am I missing something.
