Working directory when preparing package for testing in test()

[krlmlr]

When testing a package using devtools::test(), the current working directory for executing the package's code ("installing" the package into a temporary environment) seems to be the R subdirectory of the package, whereas it's the package's root directory when using devtools::check().

Test package: https://github.com/krlmlr/test.getwd

Output with devtools::test() (copied from RStudio's console):

In package: /home/muelleki/git/R/test.getwd/R

Output with devtools::check(): https://github.com/krlmlr/test.getwd/blob/master/test.getwd.Rcheck/00install.out#L4

EDIT: It's the same with devtools::document().

Is this by design? Otherwise I'd like to take a look at this, so that the CWD is always the package's root.

This is important when the package wants to access stuff in inst/ during installation: This seems to work with R, but doesn't when testing using devtools::test().

I think that's an accident - it should match R CMD check as closely as possible.

But I think you should always be able to use system.file() to get files in inst/

Are you using the version of devtools that lets you call test() and other functions from any subdirectory, and is your current working directory the R/ subdirectory? I believe devtools::test() just runs in the current working dir.

@hadley: Thanks -- system.file seems to return the correct path. However, this means that I need to figure out the name of the package that is being installed -- getNamespaceName(parent.frame()) didn't produce useful results for the test() and document() cases but works for R CMD check and R CMD INSTALL. (I'll take a look at this issue as well -- according to getNamespaceInfo it seems that we need to place an object named .__NAMESPACE__. in the package's environment.) I have updated the test package.

@wch: No, CWD is package root when running those tests.

Btw. packageName() is supposed to give you the name of the package is it called from, but I am actually not sure if it works from devtools.

[krlmlr]

Code is explicitly loaded with R/ as current directory: https://github.com/hadley/devtools/blob/master/R/load-code.r#L26.

@gaborcsardi: Thanks, didn't know that. This function expects an object named .packageName in the environment. Actually, both packageName() and getNamespaceName(...) seem to work from devtools -- not sure why I assumed otherwise.
