expect_length

Provides a lightweight (zero-dependency) and easy to use
unit testing framework. Main features: install tests with
the package. Test results are treated as data that can be stored and
manipulated. Test files are R scripts interspersed with test commands, that
can be programmed over. Fully automated build-install-test sequence for
packages. Skip tests when not run locally (e.g. on CRAN). Flexible and
configurable output printing. Compare computed output with output stored
with the package. Run tests in parallel. Extensible by other packages.
Report side effects.
