Initial testthat used a style of testing that looked like expect_that(a, equals(b))) this allowed expectations to read like English sentences, but was verbose and a bit too cutesy. This style will continue to work but has been soft-deprecated - it is no longer documented, and new expectations will only use the new style expect_equal(a, b).
