Stressful App Test

This article relies on the live media created here.

Stressful Application Test is a memory testing tool, notably used by Google.

Running the test

After you boot into the media, click the Debian logo in the top-left corner, then click “Terminal Emulator” to open the terminal:
In the terminal, do the following:
- Install StressAppTest via the terminal by typing:
  Terminal window
```
apt install stressapptest
```
- Run the application by typing stressapptest -W -s <time>. Replace <time> with the time in seconds that you want to run the test for. We suggest an hour, so the command would be stressapptest -W -s 3600. Then press Enter to actually run the command.
  Terminal window
```
stressapptest -W -s 3600
```

StressAppTest Killed

Sometimes, the linux OOM (Out-Of-Memory) killer stops memory-intensive processes to prevent system-wide lockups when it runs out of RAM. In this case, it will kill StressAppTest.

On low memory systems, implement a RAM limit on stressapptest by adding the -M flag: stressapptest -W -s <time> -M <memory>.

An example would be (run StressAppTest for 1 hour, allocate 4 GB of memory):
Terminal window
stressapptest -W -s 3600 -M 4G
