Module mutation 

The dynamic half of mutation testing: the runner protocol, the embedded companion, the transport, the scheduler and the result model.

The static half (selection, the test map, pruning, ranking and the instrumented code) is fallow_engine::mutation. The entry points are crate::run_mutation and crate::plan_mutation.

Structs

MutationRunOptions

Options of crate::run_mutation and crate::plan_mutation.

Enums

MutationRunScope

The code that a mutation run mutates.

Operator

One mutation operator.

Constants

MAX_VERDICT_INPUT_BYTES

The largest verdict document that the join reads.

Functions

apply_mutation_verdicts

Applies a verdict document to report.

baseline_blocked_run_error

The error of a run in which no mutant got a test result while tests failed with no active mutant.

last_mutation_report_path

The path of the saved report of the last run of the project.

save_last_mutation_report

Saves the JSON report of a run as the last report of the project, and returns its path. The write goes to a temporary file first, so a reader never sees half a report.
