Editing Unit testing (section)

=== Language-level unit testing support ===
Some programming languages directly support unit testing. Their grammar allows the direct declaration of unit tests without importing a library (whether third party or standard). Additionally, the Boolean conditions of the unit tests can be expressed in the same syntax as Boolean expressions used in non-unit test code, such as what is used for {{code| lang = java |if}} and {{code| lang = java |while}} statements.

Languages with built-in unit testing support include:
