FileNotFoundException for metdata.xml file while running a particular case about shot HOT 13 CLOSED

Hi @arjungovindgv

I think I had this very same problem when the emulator didn't have write permissions for the sdcard or there was a major problem running tests (some sort of crash). Try deleting and creating the emulator again and see how it goes. Another thing to watch here is the facebook's dependency version.

You can find a working project here: https://github.com/Karumi/KataScreenshotKotlin. Try cloning the repo and executing ./gradlew executeScreenshotTests -Precord to see if it's a problem with the emulator or the library.

@Serchinastico If its a permission issue ? then how the entire test suite will run but not for it's very first test class.
I tried with Real Device too.. got the same problem

For my project too, its running perfect with ./gradlew executeScreenshotTests -Precord but not for the particular test method or class
Thanks for the immediate Reply

I meant write permissions as in the file system permissions, not in the AndroidManifest declaration way. Anyways it was just a wild guess as I'm lacking some context here. If I'm understanding your problem right it's that running a single test class fails with the "no such file..." error message, isn't it? Are you sure you are running the command with the whole package name + class name? As in

./gradlew clean executeScreenshotTests -Pandroid.testInstrumentationRunnerArguments.class=com.karumi.ui.view.MainActivityTest

Try running that on the sample project (https://github.com/Karumi/KataScreenshotKotlin) and see if it works. Once you run it we will know if the issue is in the emulator, in your project's configuration or the library itself.

Hi @Serchinastico

Sample Project working fine. Even for my project test is running perfectly getting error in report generation part alone that too on running a particular class or method

Logcat trace :

If the project I linked you is working try comparing its dependencies and project configuration. More specifically, see if there is any difference in the 'com.facebook.testing.screenshot:core' version. Apart from that, I'm kind of lost here without more context. Can you send us a minimal project where the lib is not working so that we can see what's happening?

@Serchinastico can you share your mail ID where I can send those fails in private for detail ?

from shot.

I'm afraid not, we try to offer support for the library, not your specific project. If you can create an open source minimal project replicating the issue we will be glad to help you and it will be way easier for us to spot the issue.

I am having a test class under

test is running fine and everthing works fine but for report generation I am getting

@Serchinastico what more info should I have to provide ? If I run the whole test suite its working fine but getting while running a particular class or method

from shot.

@Serchinastico any update on this

from shot.

@arjungovindgv why are you using androidTestImplementation('com.facebook.testing.screenshot:core:0.4.2')? This might be the issue. Could you try removing this dependency?

On the other hand, could you check the test you are executing passes just running it from Android Studio? If the issue is not related to the lib version it has to be related with how the library is saving the screenshots and we'd need to know if the test pass from Android Studio.

from shot.

Finally after removing the dependency, it got worked.
Thank you so much @pedrovgs @Serchinastico

You are welcome @arjungovindgv Thanks for using shot, we love seeing people writing tests!!!
