Testsuites: Testsuites in Boost are created by writing an appropriate Jamfile and including that Jamfile in status/Jamfile. If the testsuites are documented (as in the MultiArray library), the documentation is maintained separately from the testcase Jamfile, leading to duplication of information and the possibility of having the documentation out of sync with the Jamfile. BoostBook contains elements that describe a testsuite for both purposes: the BoostBook stylesheets can generate documentation for the testcases and also generate an appropriate Jamfile to integrate the testcases with the regression testing system.
測試套件：Boost 中的測試套件是通過編寫一個合適的 Jamfile 並將該 Jamfile 包含在 status/Jamfile 中來創建的。如果測試套件已經文檔化(像在 MultiArray 庫中)，則這些文檔的維護是獨立於測試案例 Jamfile 的，這導致了信息的重複，還可能使得文檔與 Jamfile 不同步。BoostBook 包含了描述一個測試套的各種元素，有兩種目的：BoostBook stylesheets 可以為測試案例生成文檔，也可以生成一個適合的 Jamfile 來將測試案例與回歸測試系統相集成。

Example programs: Example programs in documentation need to be duplicated in testcases to ensure that the examples compile and execute correctly. Keeping the two copies in sync is a tedious and error-prone task. For instance, the following code snippet persisted for six months:
示例程序：在文檔中的示例程序需要在測試案例中重複，以確保這些例子被正確地編譯和執行。保持兩份拷貝的同步是一件乏味而易錯的工作。例如，以下代碼片斷被保留了六個月：

std::cout << f(5, 3) >> std::endl;

The BoostBook format allows testcases to be generated by weaving together program fragments from example programs in the documentation. This capability is integrated with testsuite generation so that example programs are normal tests in BoostBook.
BoostBook 格式可以通過組合多個程序片斷，從文檔中的示例程序生成測試案例。這一能力被集成到測試套件的生成當中，這樣在 BoostBook 中的示例程序就可以進行正常的測試。
