Run RUnit package unit tests

Share:

Description

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

Usage

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

Arguments

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.

Details

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.

Value

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