 ### Fixes
 
 * avm: `avm install` no longer downloads the version if already installed in the machine ([#1670](https://github.com/project-serum/anchor/pull/1670)).
+* cli: make `anchor test` fail when used with `--skip-deploy` option and without `--skip-local-validator` option but there already is a running validator ([#1675](https://github.com/project-serum/anchor/pull/1675)).
 * lang: Return proper error instead of panicking if account length is smaller than discriminator in functions of `(Account)Loader` ([#1678](https://github.com/project-serum/anchor/pull/1678)).
