fail {testthat}

Default expectations that always succeed or fail.

Description

These allow you to manually trigger success or failure. Failure is particularly useful to a pre-condition or mark a test as not yet implemented.

Usage

fail(
  message = "Failure has been forced",
  info = NULL,
  trace_env = caller_env()
)

succeed(message = "Success has been forced", info = NULL)

Arguments

message

a string to display.

info

Character vector continuing additional information. Included for backward compatibility only and new expectations should not use it.

trace_env

If is.null(trace), this is used to automatically generate a traceback running from test_code()/test_file() to trace_env. You'll generally only need to set this if you're wrapping an expectation inside another function.

Examples

## Not run: 
test_that("this test fails", fail())
test_that("this test succeeds", succeed())

## End(Not run)
