auto_test {testthat} | R Documentation |
The idea behind auto_test
is that you just leave
it running while you develop your code. Everytime you
save a file it will be automatically tested and you can
easily see if your changes have caused any test failures.
auto_test(code_path, test_path, reporter = "summary", env = NULL)
code_path |
path to directory containing code |
test_path |
path to directory containing tests |
reporter |
test reporter to use |
env |
environment in which to execute test suite. Defaults to new environment inheriting from the global environment. |
The current strategy for rerunning tests is as follows:
if any code has changed, then those files are reloaded and all tests rerun
otherwise, each new or modified test is run
In the future,
auto_test
might implement one of the following
more intelligent alternatives:
Use codetools to build up dependency tree and then rerun tests only when a dependency changes.
Mimic ruby's autotest and rerun only failing tests until they pass, and then rerun all tests.
