# Automated tests: Tips
|
|
|
|
If you run tests in debug mode, e.g. when debugging memory leaks, the test logs are often dominated by `++DOMWINDOW`, `++DOCSHELL`, `--DOMWINDOW`, `--DOCSHELL` lines.
|
|
|
|
These lines pollute the test logs making it difficult to find real problems. They also slow down our tests because they are not useful for debugging DevTools issues.
|
|
|
|
You can add this to your `.zshrc` or `.bashrc` to disable them:
|
|
|
|
```bash
|
|
# Disable those annoying +++DOMWINDOW and +++DOCSHELL printfs from Firefox logs
|
|
export MOZ_QUIET=1
|
|
```
|
|
|
|
You can also send `MOZ_QUIET` when you push to try… it makes the logs easier to read and makes the tests run faster because there is so much less logging.
|
|
|
|
Example try syntax containing `MOZ_QUIET`:
|
|
|
|
```
|
|
./mach try -b do -p linux,linux64,macosx64,win32,win64 \
|
|
-u xpcshell,mochitest-bc,mochitest-e10s-bc,mochitest-dt,mochitest-chrome \
|
|
-t damp-e10s --setenv MOZ_QUIET=1
|
|
```
