So I am running a few tests in AndroidJunit, which tests a manager class that I created for my application. When I add breakpoints to the Test class and go into debug mode, they get hit just fine. But if I add break points to the Manager class that I am testing in junit, they do not get hit when I run the tests. Is it possible to hit break points in a non-test class when running junit in Android Studio? I'd appreciate any suggestions on how to solve this issue. Logs also do not show up when I place them outside of the Test class.
EDIT/UPDATE
So I have been able to dig a little deeper and found out that the problem here was using Mockito with my Tests. So if I replace InstrumentationRegistry.getContext() with context = Mockito.mock(Context.class); then the debugger no longer hits the breakpoints placed in the manager. However, I need to use Mockito with my tests, so I'm in a bit of a predicament. Does anyone if there is a manner that I can use Mockito in that allows me to set and reach break points in a non-test class? Thank you.
FYI, I am passing context into the manager class method like this
manager.checkSharedPreferences(context), and the manager is extracting values from shared preferences.

I want to write an Androidx test that starts an Application, waits for it to crash, and then starts it again.
As I understand it, by default, AndroidX tests run on a instrumentation, and when one test crashes, the entire instrumentation is brought down with it.To prevent one test from crashing the whole test suite, AndroidX includes an AndroidTestOrchestrator. This allows each test to run in its own instrumentation, so one test crashing only brings down the instrumentation it is in.
Given what I am trying to do, it looks like I will need to create my own AndroidTestOrchestrator to run a test with two instrumentations, one to run the Application crash, and then another to see that it is recovered from correctly.
How feasible is this?
Is there a way to create an espresso test file from a class like does Command / Control+Shift+T?
Same for launch the current test with espresso into the device?
It's very annoying to create/launch every test manually through the whole process of going to the file's hierarchy and then create the launch configuration of it. Neither an option is hidden in options?
If I remember well, these functionalities were available on Android Studio 2.3, I noticed the lack of them from AS3.0. Where did they go?
As today, Android Studio 3.1.1 comes with the functionality just as before
Every time I want to do a quick test of some code, android studio takes 20-40 minutes loading an emulator which then either crashes my laptop or makes it run very slow. Is there any way to just use the system log without loading the whole app, similar to the System.out.Prinln() feature in net beans?
I understand that the question is about running your app for quick testing and not about automated tests. But you can learn a lot by trying to adapt writing tests, and they can help you to solve your problem.
1) For code without android dependencies you can write JUnit tests and run those just on JVM to test the code. Bonus: you'll start with creating your testsuite!
2) For code with android dependencies: a) Try to be better in separating platform specific code and internal logic so you will be able to cover more code with unit tests. b) You can use roboelectric and test everything without emulator/device for the rest.
So i recently started using Robotium for the first time and noticed after some time that they are Executed in an alphabetical order. This made some test not work, because i needed the "introduction" of my app to be finished and than start other tests.
Since i have never used Automated tests before, im not sure how to write the tests right now. Should all the test cases ALWAYS be independent from each other?
This would mean in my case, that the flag for the introduction should be set false for some tests and true for other tests programmatically.
Or is it also right to assume that one test case has been Executed before another one?
This is correct. You should always build tests so they can run independently. Also take note to ensure you have a rollback process after running your tests. Otherwise the next time they might not run.
There is a lot to consider when writing automated tests.
I would say yes. All tests should always be independent from each others. That way your sure that another test is not the reason for the failing test case.
I am working in Android app that is already developed and I need to write test case for this app in Android Studio. I want to know how to write test case in Android Studio ?
I also want to know what is main propose of writing test case? How to test app that we are writing write test cases?
I have made test folder
public class LoginActivityTest extends ActivityInstrumentationTestCase2<LoginActivity> {
private static final String LOGIN_DIALOG_FRAGMENT_TAG = NestAlertDialog.class.getSimpleName();
private LoginActivity mActivity;
private MainActivity mMainActivity;
public LoginActivityTest() {
super(LoginActivity.class);
}
I have made test folder
Atm(Android Studio 1.1.0) when you create a project AS takes care of creating a testing folder inside your app under /app/src/androidTest.
You can still create a test project directory elsewhere if you prefer, or you can try to follow the official website notes on testing.
I want to know how to write test case in android studio
I suggest you to start by downloading the sample code activityInstrumentation. From Android Studio, File -> Import Sample.
Later you can check the documentation to develop further and more complicated test.
You can check this as further reference too.
What is main propose of writing test case
If your program is simple and does not goes beyond 100 LOC test case are probably useless, just the bigger the project gets the harder is to debug. You can have test cases for every tiny piece of code composing your application, thus ensuring that your entire application works correctly.
You can also write your application by writing its test cases before a single line of code as with Test Driven Development.
