## Test Installed Packages

### Description

These functions allow an installed package to be tested, or all base and recommended packages.

### Usage

testInstalledPackage(pkg, lib.loc = NULL, outDir = ".",
types = c("examples", "tests", "vignettes"),
srcdir = NULL, Ropts = "", ...)

testInstalledPackages(outDir = ".", errorsAreFatal = TRUE,
scope = c("both", "base", "recommended"),
types = c("examples", "tests", "vignettes"),
srcdir = NULL, Ropts = "", ...)

testInstalledBasic(scope = c("basic", "devel", "both", "internet"))


### Arguments

 pkg name of an installed package. lib.loc library path(s) in which to look for the package. See library. outDir the directory into which to write the output files: this should already exist. types type(s) of tests to be done. errorsAreFatal logical: should testing terminate at the first error? srcdir Optional directory to look for .save files. Ropts Additional options such as -d valgrind to be passed to R CMD BATCH when running examples or tests. ... additional arguments use when preparing the files to be run, e.g. commentDontrun and commentDonttest. scope Which set(s) should be tested? Can be abbreviated.

### Details

These tests depend on having the package example files installed (which is the default). If package-specific tests are found in a ‘tests’ directory they can be tested: these are not installed by default, but will be if R CMD INSTALL --install-tests was used. Finally, the R code in any vignettes can be extracted and tested.

Package tests are run in a ‘pkg-tests’ subdirectory of ‘outDir’, and leave their output there.

testInstalledBasic runs the basic tests, if installed. This should be run with LC_COLLATE=C set: the function tries to set this by it may not work on all OSes. For non-English locales it may be desirable to set environment variables LANGUAGE to ‘⁠en⁠’ and LC_TIME to ‘⁠C⁠’ to reduce the number of differences from reference results.

Except on Windows, if the environment variable TEST_MC_CORES is set to an integer greater than one, testInstalledPackages will run the package tests in parallel using its value as the maximum number of parallel processes.

The package-specific tests for the base and recommended packages are not normally installed, but make install-tests is provided to do so (as well as the basic tests).

### Value

Invisibly 0L for success, 1L for failure.
