+# End To End Tests

+#### What is this?!?
+These are end to end tests written in bash. They need bash, vim and git to be run.
+They use real internet connection to download plugins from github, so you cannot run them without it.
+
+#### To run a specific test:
+```bash
+$ bash test/end2end/nameOfTest.sh
+```
