Evaluates code
in a special context in which all output is captured,
similar to capture.output()
.
capture_output(code, print = FALSE, width = 80) capture_output_lines(code, print = FALSE, width = 80) testthat_print(x)

capture_output()
returns a single string. capture_output_lines()
returns a character vector with one entry for each line
Results are printed using the testthat_print()
generic, which defaults
to print()
, giving you the ability to customise the printing of your
object in tests, if needed.
