Robotic tests should be independent - android

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.

How do you write an Androidx Instrumentation that runs multiple Instrumentations?

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?

Android Studio: testing is slow

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.

Spoon & Espresso - Build Successful. Thats it?

I run my Espresso test via Spoon. Often, I get a build successful, with tests not being executed. I assume the cause is there was no alterations to the code of the app in question. I can see why they would do this - Why test an app that just ran the same test and passed? However, my situation is different; testing the app is not my primary concern, but testing what the app controls.
My question: My test will be run on a continuous loop, and the app will not be altered or changed. So is there any way around this?
I assume the cause is there was no alterations to the code of the app
in question.
This is not true. You can run the same test thousands of times with Espresso without changing a line of code.
Make sure you're running it the correct way:
java -jar spoon-runner-1.1.0-jar-with-dependencies.jar \
--apk example-app.apk \
--test-apk example-tests.apk
Also keep in mind that the devices running the test should be visible in adb (run adb devices to check).
With Spoon, a test will not run twice if the first test passed. This is cause it believes if it runs the test again, it will pass and there is no reason for that. Bad design on Square's part if you ask me.
The solution is: gradle clean spoon. clean will regenerate the res files (among others) and make spoon believe that it is essentially a different test. This makes running tests take longer than it should. But it works.

Is there a way to check that emulator is controller by monkeyrunner?

I want to put some conditions in my code to behave one way, if it's tested by monkeyrunner and another way, if it's used by a user.
How to check that in tested application that emulator/application is driven by monkeyrunner?
P.S. I am aware that it's bad practice to do such checks (the code under test should be the same code as in production). However, it's for one off case, which is hard to handle other way.
I didn't find a clean way to check that except uploading a file to a Emulator/device as part of MonkeyRunner tests and after checking for it in application source code.

Android Junit Test Cases

How can I stop the android Junit test application in the mid.I want to stop the execution of my application in particular place.Is it possible?Please give your suggestion..
Set the breakpoint in desired place in IDE and run test project in debug mode.
Note that debug execution is a bit slower than run mode.
hope this answer satisfies your question
click on the stop button in the junit column. But again if you return, the testcases will be running from the beginning.
