Android :: Unit Testing The Platform
Jul 14, 2010I was finally able to build and debug the android platform (the process can be seen here). Now, the question is: where are the unit tests, how do I launch them and where do I see results? And also, is there any guide to android platform architecture?
View 1 Replies View RelatedAndroid :: Unit Testing Localizations ?
Nov 17, 2010There is no way to load a string from a specific locale's language file.
What I want to do is run all my locales' (I have 24 of them) time format strings through unit tests to make sure they don't crash. For example, here's a date format string in French: "'Hier à ' h:mm a".
These really need to be unit tested, because translators aren't great about properly escaping these strings, causing crashes unless we manually verify every string in every language every time we get a translation pass back.
This question has a sort-of answer. Is that really the only way? Is there a better way to specify the locale of a Context in unit tests?
Android :: Unit Testing With Test Only Assets
Jul 3, 2009I 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 RelatedAndroid :: Unit Testing & Using A Different Database File
Mar 30, 2010I'm trying to start unit testing on my application (should have done so from the beginning). I've got an Eclipse project structure set up and everything seems to work well, but...
I'm subclassing SQLiteOpenHelper to access the application database. This works well for the application, but when using the same class in the unit tests, it writes to the same database as the actual application. This is obviously rather irritating, since unit test data shows up when developing and testing the actual application.
What's the best way to make the SQLiteOpenHelper class write to a different database file when being called from the unit tests?

Android :: Unit Testing Project Gets A NoClassDefFoundError For 3rd Party Jars

Android :: How To Refactor Class So I Can Unit Test It?
May 21, 2010I 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?

I want to test things like constraints, look at the data, unit test methods, etc. Is there any kind of GUI tool that I can hook up to the emulator to be able to look at the db of a particular app while I'm developing/testing, or are my only options the adb shell and creating test Activities within my app?

Jan 27, 2010I 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)?

Android :: What Difference When A Class Extend From Handler And Thread? - In Framework
Mar 18, 2010What is the difference when a class extend from Handler and Thread?
As described in developer.android.com
...
Each Handler instance is associated with a single thread and that thread's message queue.

Does the thread has no message queue ?
Any benefit for a class extend from Handler?
Android :: Handler Class And The Timing Of When Its Message Queue Is Emptied
Sep 6, 2010I 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.

Android :: Android Functional Testing - Testing Multiple Activities
Apr 16, 2009I've been exploring the Android test package and I'm very confused on how to implement functional testing for endpoint-to-endpoint.
Consider the example below, I have 4 activities: 1. A Contact List Activity 2. A View Contact Activity 3. An Add/Edit Contact Activity 4. A Sync Contact List activity
I want to automate a few tests that will go through multiple test cases simulating a user experience: From launching the application, to selecting 'Add contact;' opening the add contact activity, entering data, saving it, going back to the list activity, and verifying the new contact was saved properly.
As I understand it, ActivityInstrumentationTestCase<T extends Activity> and ActivityUnitTestCase<T extends Activity>, are only useful for testing single activity functionality.
But what if I need to switch between 2 or more activities inside a single functional test case?

View 4 Replies View RelatedAndroid :: Communicating Between Receiver Class And An Activity Class
Jul 14, 2010I'm just getting into Android development, and I have a question about communicating between a receiver class and an activity class. I'm very new to JAVA and Android so I hope I don't sound too stupid. I'm developing an application where I intercept an SMS message and then based on various elements of that SMS I might delete it once it's been saved to the inbox. I have a receiver class that intercepts the txt message, and I am also able to delete messages from my inbox with code in the activity class using a button at the moment. The problem I have is communicating between the receiver class and the activity class where the code to delete a message resides. I tried putting that code directly into the receiver class but as I'm sure most of you already know the BroadcastReceiver class doesn't seem to support what I need to delete messages. I've been searching for an answer to this for a while, but haven't been able to find anything. Honestly I'm not sure I know enough about JAVA and Android to even recognize a solution if I saw it.
