Create a plan for mutation testing

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

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.
