- * 注意事项： - *

- *
    - *
  • Assertion是用来明确设置程序中的条件和约定的，它是一种程序员之间交流的工具，而不是和最终用户交流的工具。
    • - *
  • 一个经过完整单元测试的正确程序，不应该使任何一条assertion失败。
    • - *
  • 应避免过于复杂的assertion条件，而占用过多的运行时间。除非Assertion失败。
    • - *
  • Assertion的出现异常信息不是给最终用户看的，因此没必要写得过于详细，更没必要考虑国际化的问题，以至于浪费CPU的时间。 - * 例如下面的语句是要避免的： - *

    - * 

    - * assertTrue(type instanceof MyType, "Unsupported type: " + type);
- *
    - *

    - * 可以替换成： - *

    - * 

    - * assertTrue(type instanceof MyType, "Unsupported type: %s", type);
- *
    - *

    - * 这样，当assertion顺利通过时，不会占用CPU时间。

    • - *
- *

- * 此外，部分方法具有返回值，以方便编程，例如： - *

- *

- * 

- * void foo(String param) {
- *     bar(assertNotNull(param));
- * }
- *
- * int bar(String param) {
- *     if (true) {
- *         ...
- *     }
- *
- *     return unreachableCode();
- * }
- *
