Clarification on test method naming rules in Section 5.2.3

[vivek-0509]

In Section 5.2.3 Method Names, the style guide states:

"Underscores may appear in JUnit test method names to separate logical components of the name, with each component written in lowerCamelCase, for example transferMoney_deductsFromSource."

Case that needs clarification:

Single-word components in test method names

@Test void test_foo() {}
@Test void testing_name() {}

The style guide states that underscore-separated components must be written in lowerCamelCase, but it does not clarify whether a single-word identifier (e.g. foo, name) qualifies as acceptable lowerCamelCase in this context, or whether each component is expected to consist of multiple camel-case words.

Clarification requested

Should each underscore-separated component in JUnit test method names:

• Be allowed to be any valid lowerCamelCase identifier, including single-word names like foo or name (e.g. testing_foo), or
• Require every component to consist of multiple lowerCamelCase words (e.g. transferMoney_deductsFromSource), or
• Require only the segments after underscores to be proper multi-word lowerCamelCase (e.g. test_deductsFromSource where test is single-word but deductsFromSource is multi-word)

Thank you!
