testPackage: Run RUnit package unit tests
In BiocGenerics: S4 generic functions used in Bioconductor

Description Usage Arguments Details Value See Also Examples

testPackage helps developers implement unit tests using the RUnit testing conventions.

1 2	testPackage(pkgname=NULL, subdir="unitTests", pattern="^test_.*\\.R$", path=getwd())

`pkgname`	The name of the package whose installed unit tests are to be run. A missing or NULL value implies that the `testPackage` command will look for tests within the package source directory indicated by `path`.
`subdir`	A character(1) vector providing the subdirectory in which unit tests are located. The directory is searched first in the (installed or source) package root, or in a subdirectory `inst/` below the root.
`pattern`	A character(1) regular expression describing the file names to be evaluated; typically used to restrict tests to a subset of all test files.
`path`	A character(1) directory path indicating, when `pkgname` is missing or NULL, where unit tests will be searched. `path` can be any location at or below the package root.

This function is not exported from the package namespace, and must be invoked using triple colons, BiocGenerics:::testPackage(); it is provided primarily for the convenience of developers.

When invoked with missing or NULL pkgname argument, the function assumes that it has been invoked from within the package source tree (or that the source tree is located above path), and finds unit tests in subdir="unitTests" in either the base or inst/ directories at the root of the package source tree. This mode is useful when developing unit tests, since the package does not have to be re-installed to run an updated test.

When invoked with pkgname set to the name of an installed package, unit tests are searched for in the installed package directory.

The function returns the result of RUnit::runTestSuite invoked on the unit tests specified in the function call.
