check: Apply passif/failif/okif tests to an identified code object

In dtkaplan/checkr: Facilities for checking R submissions in tutorials

Description

A generic testing function for applying passif/failif tests with V and EX bindings to a checkr_result object. Unlike line_where(), other line functions, no patterns need to be provided. Just the passif/failif tests.

Usage

check(ex, ..., message = "Sorry!")

Arguments

ex	the checkr_result object with a single line of code
...	passif/failif tests to be applied
message	a character string to be used as the message for a failed result

Value

a checkr_result object reflecting the outcome of the tests

Examples

code <- for_checkr(quote({x <- 3; y <- x^2 + 2}))
line2 <- line_where(code, insist(Z == "y"))
check(line2, passif(V == 11, "Right, eleven!"),
      message = "Sorry. The result should be 11.")
