docs/bugpattern/SimplifyTestParameter.md

When using `TestParameterInjector`, annotating a `boolean`, `Boolean`, or `Enum`
parameter or field with `@TestParameter` automatically injects all possible
values (note that it does not inject `null`). Explicitly specifying all values
is redundant, and for enums, omitting the explicit list ensures the test will
automatically run for any new values added to the enum in the future.

```java
@Test
public void someTest(
    @TestParameter({"true", "false"}) boolean foo,
    @TestParameter({"HEARTS", "DIAMONDS", "CLUBS", "SPADES"}) Suit suit) {
  ...
}
```

```java
@Test
public void someTest(@TestParameter boolean foo, @TestParameter Suit suit) {
  ...
}
```
