testthat 0.8 (and 0.8.1)

We’re pleased to announce a new major version of testthat. Version 0.8 comes with a new recommended structure for storing your tests. To better meet CRAN recommended practices, we now recommend that tests live in tests/testthat, instead of inst/tests. This makes it possible for users to choose whether or not to install tests. With this new structure, you’ll need to use test_check() instead of test_packages() in the test file (usually tests/testthat.R) that runs all testthat unit tests.

Another big improvement comes from Karl Forner . He contributed code which provides line numbers in test errors so you can see exactly where the problems are. There are also four new expectations (expect_null(), expected_named(), expect_more_than(), expect_less_than()) and many other minor improvements and bug fixes. For a complete list of changes, please see the github release . After release of 0.8 to CRAN, we discovered two small bugs. These were fixed in 0.8.1 .

As always, you can install the latest version with install.packages("testthat").

Recreating Septa Transit Timetables in Python

Recently, Rich and I were poking around transit data, and we were struck by the amount of structuring that goes into transit timetables. For example, consider this weekend rail schedule table from SEPTA, Philadelphia’s transit agency. Notice these big pieces: The vertical text on the left indicating trains are traveling “TO CENTER CITY”. The blue header, and spanner columns (“Services” and “Train Number”) grouping related columns. The striped background for easier reading. Also the black background indicating stations in Center City (the urban core). Tables like this often have to be created in tools like Illustrator, and updated by hand. At the same time, when agencies automate table creation, they often sacrifice a lot of the assistive features and helpful affordances of the table.
