Create a plan for mutation testing

muttest_plan.Rd

Each mutant requires rerunning the tests. For large project it might be not feasible to test all mutants in one go. This function allows you to create a plan for selected source files and mutators.

Usage

muttest_plan(mutators, source_files = fs::dir_ls("R", regexp = ".[rR]$"))

Arguments

mutators

A list of mutators to use. See operator().

source_files

A vector of file paths to the source files.

Value

A data frame with the test plan. The data frame has the following columns:

  • filename: The name of the source file.

  • original_code: The original code of the source file.

  • mutated_code: The mutated code of the source file.

  • mutator: The mutator that was applied.

Details

The plan is in a data frame format, where each row represents a mutant.

You can subset the plan before passing it to the muttest() function.
