Robotium on APK files using Android studio

[Stanojko Markovik]

Hello everyone,
I am trying to setup a project with Android studio for my QA team to start building blackbox automation tests using robotium.

So the idea is, the tester will get the APK from the build server, resign with the re-sign.jar utility I got from your site, and then
start their android studio to develop tests using Solo, (we plan to also get a license for the recorder, but first off step1 needs to work)
the idea is that I want them to be able to do complete blackbox testing.

However when I try to start a simple test, the test suite breaks and tells me that it cannot instantiate the class I am calling from the UI
Package names are all good, tests are failing due to the following error.

Could you help ?


This is my error log  :

Hi, 

when you sync your project using gradle - what happened ? 

plus I am in between writing a tutorial to set up Robotium around studio, will be up soon. 

Naveed

Hey, 

gradle sync works like a charm, 

Can I get an early preview of the doc? 

I can help probably as I am working on setting up a standalone project for a blackbox app... 

Would it help if I modify my project to bind to facebook for example and send it to you ? 

Best, 
Tancho

[naveed]

Yap sure

Naveed

[Stanojko Markovik]

Hello Naveed, 

here you go 

I modified the project to work with Instagram, 

From what I can see as Android Studio doesn't have an explicit "run as instrumentation test" 

it's trying to uninstall com.instagram.android as it's comparing to it's own build number or something.. 

attached : the zip file with a single automated test... 

can I have the preview howto for setting it up with Studio? 

thanks

Tancho

[Stanojko Markovik]

hey Naveed,

any updates on this?

could you help me run a blackbox (apk) test in robotium?

Best

Tancho

I'm interested in black box testing too (expecially setting up and running tests with Android Studio) can you point me to an updated tutorial?

[Renas]

We will add new tutorials for black box testing in Android Studio shortly. In the meantime I can recommend you to use a free trial of Robotium Recorder and see how it does it. Have a look at the build.gradle that Robotium Recorder generates for the test project.
