Re: [android-developers] ContentProvider contains dirty data from a previous JUnit test
I haven't tested with the MockContentProvider, but I'm pretty sure that you just need to create one in the JUnit setup() routine and clear it in the teardown(). Make it a member of the JUnit class. I saw several detailed posts after doing a Google search, have a look here:http://www.jayway.com/2011/10/10/using-renamingdelegatingcontext-to-mock-contentresolver-in-android/ -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] ContentProvider contains dirty data from a previous JUnit test
As I read your reply, I'm confused now about what's being tested. Are you testing the ContentProvider or the Activity? If testing the Activity, it may be better to create a MockContentProvider that's responsible for providing back the info. If testing the ContentProvider, skip the Activity and use an Application test case, as you get direct control of when its created or destroyed. Sometimes its hard to do, but the goal in testing is to isolate the components and build known conditions around them. -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] ContentProvider contains dirty data from a previous JUnit test
In this case, I am testing the activities of my app with ActivityInstrumentationTestCase2. (I also have tests for the ContentProvider using ProviderTestCase2.) The two tests that I outlined earlier are for the data entry activity. I want to verify that the data entered is inserted into the underlying database. The Activity inserts the data via `getContentResolver.insert()`. The test case then opens the database directly to assert that the data is there. How would I use a MockContentProvider and/or other mock objects to perform this kind of testing?

Re: [android-developers] ContentProvider contains dirty data from a previous JUnit test
I think you're seeing normal Unix (and Linux) file system semantics, with respect to deleting a file that's currently open. This unlinks the name from the underlying file system, but the file itself continues to stay open, and has same content as before unlinking -- until the process that has the file open terminates. So, if you're going to execute both tests in one run, you need a way to reset the database some other way. One method would be to ensure that the CP closes the database before deleting the files (then reopens). Another would be to delete all data (DELETE FROM tablename). Yet another would be to drop all tables (and to re-create them). In any case, you'll need a way for your test code to trigger this code inside the CP. One way to do this would be to create a special purpose content:// URI and call it from the test code (and the CP would recognize it and reset its data using one of the methods above). -- K 2014-02-24 1:33 GMT+04:00 Code Guru codegur...@gmail.com: In this case, I am testing the activities of my app with ActivityInstrumentationTestCase2.

[android-developers] ContentProvider contains dirty data from a previous JUnit test
Two of my JUnit tests against my app pass when I run them separately but fail when run consecutively. The two tests run through the following sequence of actions: *Test 1:* 1. Insert a single row to the database. This all occurs within the app using getContentResolver().insert(). 2. Clean up the test. In particular, I delete the database using context.deleteDatabase(DB_NAME);. *Test 2:* 1. Insert multiple rows to the database. This again occurs within the app using multiple calls to getContentResolver.insert(). The data inserted to the database includes the data for the single row from Test 1. When this row of data is reached in test 2, the test fails. From what I can tell, the ContentProvider in Test 2 still sees the data added during Test 1. I suspect this is due to my method of cleaning up the test. I verified with adb shell that the database file is deleted when Test 1 cleans up and that it is recreated when Test 2 starts. How do I correctly clean up the first test so that the second test doesn't? I guess I could split the two test methods into two separate classes. Even if this works, it means that I will have to split up other classes with even more test methods that experience the same issue. Does anyone have other suggesions?

[android-developers] ContentProvider contains dirty data from a previous JUnit test
Is the object instance for the content provider different between test runs? How are you destroying and recreating the ContentProvider? I suspect that if the Application instance is the same between test runs the ContentProvider might be too. It's created at the Application level through the manifest, so you may need to use an ApplicationTestCase or something similar to be sure that the App instance is killed and restarted between tests. -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] ContentProvider contains dirty data from a previous JUnit test
The `ContentProvider` is created indirectly by calling `getContentResolver()` from inside a method of the `Activity` under test. I will have to look into using `ApplicationTestCase` as you suggest.

Re: [android-developers] ContentProvider contains dirty data from a previous JUnit test
My current test class extends `ActivityInstrumentationTestCase2`. If I change it to extend `ApplicationTestCase`, how do I start an activity?
