java.lang.OutOfMemoryError

[mgmanikandan87]

I am getting out of memory error while taking screenshot more than 10 .

please let know why it happen.

Testing environment : Samsung galaxy note with no sdcard

On the device? On the computer? Stacktrace?

In my case, the device seems to be affected. Test execution slows drown drastically, entry into a Textview is done around 1 character every 10 seconds

We buffer logs. If you have long tests with a ton of tests it'll eventually
run out.

#151 (comment).

Would it be a side effect then if the tests start slowing down over time? or is the fact that the execution is taking forever just piling up logcat?

[yogurtearl]

Also, this can also happen if you have LOTS of logcat output. Espresso can be fairly verbose.
Check the logs ( in verbose mode ) and see if there is anything that you don't need and can turn off.

#112 would allow you to allocate more memory.

Same issue happening on device with many UI tests and taking a lot of screenshots. I'm using FalconSpoon wrapper to handle dialog screenshots.
