#### doRUnit.R --- Run RUnit tests

####------------------------------------------------------------------------

### borrowed from package fUtilities in RMetrics

### http://r-forge.r-project.org/plugins/scmsvn/viewcvs.php/pkg/fUtilities/tests/doRUnit.R?rev=1958&root=rmetrics&view=markup

### Originally follows Gregor Gojanc's example in CRAN package 'gdata'

### and the corresponding section in the R Wiki:

### http://wiki.r-project.org/rwiki/doku.php?id=developers:runit

### MM: Vastly changed: This should also be "runnable" for *installed*

## package which has no ./tests/

## ----> put the bulk of the code e.g. in ../inst/unitTests/runTests.R :

if(require("RUnit", quietly = TRUE)) {

pkg <- "Rcpp"

require( pkg, character.only=TRUE)

path <- system.file("unitTests", package = pkg)

stopifnot(file.exists(path), file.info(path.expand(path))$isdir)

# without this, we get unit test failures

Sys.setenv( R_TESTS = "" )

Rcpp.unit.test.output.dir <- getwd()

source(file.path(path, "runTests.R"), echo = TRUE)

} else {

print( "package RUnit not available, cannot run unit tests" )

}
