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)
Code to evaluate.
If TRUE
and the result of evaluating code
is
visible, print the result using testthat_print()
.
Number of characters per line of output. This does not
inherit from getOption("width")
so that tests always use the same
output width, minimising spurious differences.
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.
