and for a failing project:

$ python3 infra/helper.py check-tests --integrity-check cups
...
> -#~ msgstr "Utilização: cups-x509 [OPÇÕES] [COMANDO] [ARGUMENTO]"
> -
> -#, c-format

> -#~ msgstr "O URI '%s' não é válido para o cups-x509."

> -#~ msgid "cups-x509: Unable to connect to '%s' on port %d: %s"
> -#~ msgstr "Não foi possível conectar '%s' na porta %d de %s para o cups-x509"

Patch result: failed. Patch found that affects source control versioning.
INFO:chronos.manager:succeeded patch: False
INFO:chronos.manager:run_tests.sh result failed: patches source control
INFO:chronos.manager:cups test completion failed: Duration of run_tests.sh: 278.28 seconds

Cups is failing because it patches the source control (fix in #14291).
