Identify equivalent mutants using OpenAI API — identify_equivalent

Analyzes survived mutants to determine if they are functionally equivalent to the original code using OpenAI's language models.

Usage

identify_equivalent_mutants(
  src_file,
  survived_mutants,
  api_config = NULL,
  batch_size = 25,
  workers = 1
)

Arguments

src_file: Path to the original source file
survived_mutants: List of mutants that survived test execution
api_config: Optional API configuration (will be loaded if NULL)
batch_size: Maximum number of mutants sent in a single API request. Smaller batches keep each response short enough to avoid truncation (which silently drops verdicts) and let batches run concurrently. Defaults to 25.
workers: Number of API requests to run concurrently (requires a forking platform). Defaults to 1 (sequential).

Value

Updated list of survived mutants with equivalence information

Examples

src <- tempfile(fileext = ".R")
writeLines("add <- function(x, y) x + y", src)
survived <- list(mutant_001 = list(mutation_info = "x + y -> x - y"))
suppressWarnings(identify_equivalent_mutants(
    src,
    survived,
    api_config = list(api_key = "", model = "gpt-4")
))
#> $mutant_001
#> $mutant_001$mutation_info
#> [1] "x + y -> x - y"
