===============
Mutation output is grouped by selection groups. Each group contains three sections:
1. An identifier for the current group.
**Format**:
```text
[SUBJECT EXPRESSION]:[SOURCE LOCATION]:[LINENO]
```
**Example**:
```text
Book#add_page:Book#add_page:/home/dev/mutant-examples/lib/book.rb:18
```
2. A list of specs that mutant ran to try to kill mutations for the current group.
**Format**:
```text
- [INTEGRATION]:0:[SPEC LOCATION]:[SPEC DESCRIPTION]
- [INTEGRATION]:1:[SPEC LOCATION]:[SPEC DESCRIPTION]
```
**Example**:
```text
- rspec:0:./spec/unit/book_spec.rb:9/Book#add_page should return self
- rspec:1:./spec/unit/book_spec.rb:13/Book#add_page should add page to book
```
3. A list of unkilled mutations diffed against the original unparsed source
**Format**:
```text
[MUTATION TYPE]:[SUBJECT EXPRESSION]:[SOURCE LOCATION]:[SOURCE LINENO]:[IDENTIFIER]
[DIFF]
-----------------------
```
- `[MUTATION TYPE]` will be one of the following:
- `evil` - a mutation of your source was not killed by your tests
- `neutral` your original source was injected and one or more tests failed
- `[IDENTIFIER]` - Unique identifier for this mutation
**Example**:
```diff
