 scm4j-vcs-api is set of base classes and interfaces to build VCS support (Git, SVN, etc) libraries which exposes basic vcs-related operations: merge, branch create etc.
 scm4j-vcs-api provides:
 - A simple interface to implement basic VCS-related operations
-- Set of functional tests wchich are common to each VCS implementation. Functional tests for a certain VCS implementation are done by implementing few abstract methods of base test class. Implemented in [scm4j-vcs-test](https://github.com/scm4j/scm4j-vcs-test)
 - Working copies management for operations which must be executed on a local file system
