Changelog • testit

The global option options(testit.cleanup = TRUE) (TRUE is the default) can be used to clean up additional files or directories generated in the tests/ directory during the test process.

test_pkg() installs the package before running tests when it is called from a non-interactive R session that is not launched by R CMD check, e.g., when you run tests in RStudio via Ctrl/Cmd + Shift + T, so you will not have to install the package manually (Ctrl/Cmd + Shift + B) before running tests.

The package license was changed from GPL to GPL-3 (@jayvdb #8).

test_pkg() also looks for tests under the tests/testit/ directory. This makes it easier for you to run test_pkg() under the root directory of the package, and you don’t need to change the working directory to tests/.

Added a new argument silent to has_error() (thanks, @StevenMMortimer, #6).

When %==% is used inside assert(), a message will be printed if the value is not TRUE, to show the values of the LHS and RHS, respectively.

provided an alternative way to write assertions of the form assert(‘fact’, {(condition_2); (condition_2)}); see ?testit::assert for more information

test_pkg() runs package tests with top-level environment being set to the namespace of the tested package (thanks, @kalibera, #3)
all test scripts (test-*.R) are assumed to be encoded in UTF-8 if they contain multibyte characters

added an infix operator %==% as an alias of identical() (in RStudio, you can use an add-in to insert the text %==%)
test_pkg() will print out the filename of the R script that errored

the fact argument of assert() is optional now: all arguments of assert() can be test conditions

the test files have to be named of the form test-.R (or test-.r), i.e. they have to use the prefix test-
the test environment is always cleaned (all objects removed) before the next test is run

fixed a test that failed under R 2.15.x because the argument keep.source did not exist in parse()

assert() does not use base::stopifnot() any more; a tailored version of stopifnot() is used now; see ?assert for the differences between this version and base::stopifnot(); in particular, assert(fact, logical(0)) will fail but stopifnot(logical(0)) will not

this is the first version of testit; the source code is hosted on Github: https://github.com/yihui/testit
added functions assert(), test_pkg(), has_error() and has_warning()
