在 OpenEuphoria track 上測試

執行測試

在練習目錄中，執行exercism test或eutest。 Euphoria 接著會用t_<exercise>.e來測試你的解答。

閱讀輸出結果

練習一開始時，你的解答檔案還沒有回傳值，執行時會崩潰。

C:\path\to\leap.ex:3
<0120>:: no value returned from function
end function
           ^

FAILURE: t_leap.e EUPHORIA error with status 1

Test results summary:
    FAIL: t_leap.e
Files (run: 1) (failed: 1) (0% success)

這是正常的。 實作這個函式，然後重新執行，就能看到哪些測試通過、哪些失敗。

interpreting t_leap.e:
  passed: year not divisible by 4 in common year
  failed: year divisible by 2, not divisible by 4 in common year, expected: FALSE but got: TRUE
  failed: year divisible by 4, not divisible by 100 in leap year, expected: TRUE but got: FALSE
  ...
  9 tests run, 6 passed, 3 failed, 67% success
FAILURE: t_leap.e program died with status 1

Test results summary:
    FAIL: t_leap.e
Files (run: 1) (failed: 1) (0% success)

循序漸進地完成測試

一個好的起步方式，是把t_<exercise>.e裡除了第一個測試以外的測試全都註解掉。

test_false("year not divisible by 4 in common year", leap(1800))
-- test_false("year divisible by 100 but not by 3 is still not a leap year", leap(1900))
-- test_false("year divisible by 2, not divisible by 4 in common year", leap(1970))

一次處理一個，等目前這個測試通過之後，再取消下一個測試的註解。 當所有測試都通過，就代表你完成這個練習了喔！
