Tools for testing expectations

Source: R/expect-self-test.R
expect_success.Rd

  • expect_sucess() and expect_failure() check that there's at least one success or failure respectively.

  • expect_snapshot_failure() records the failure message so that you can manually check that it is informative.

  • expect_no_success() and expect_no_failure() check that are no successes or failures.

Use show_failure() in examples to print the failure message without throwing an error.

expect_success(expr)

expect_no_success(expr)

expect_failure(expr, message = NULL, ...)

expect_snapshot_failure(expr)

expect_no_failure(expr)

show_failure(expr)
