### Verify

Spot errors sooner, improve security and shorten feedback cycles with built-in
static code analysis, code testing, code quality, dependency checking and Review
Apps. Customize your approval workflow controls, automatically test the quality
of your code, and spin up a staging environment for every code change.

GitLab Continuous Integration is the most popular next generation testing system that
scales to run your tests faster.
