FileTestStrategy: Run tests matching the mutated source file name

In muttest: Mutation Testing

Run tests matching the mutated source file name

Description

This strategy tells if a mutant is caught by a test matching the source file name.

For example, if the source file name is foo.R, and there are test files named test-foo.R or test-bar.R, only test-foo.R will be run.

This strategy should give faster results than ?FullTestStrategy, especially for big codebases, but the score might be less accurate.
