為什么要“進行測試”和“ ./test/Test”

Question

現在，我使用CMake設置一個c ++測試環境。 其實我已經意識到我想做的事情，但是我對2種不同的測試輸出樣式感到困惑。 在下面的示例中，“ make test”實際上是做什么的？ 我認為'make test'和'./test/Test'輸出都是相同的，但不完全相同。 “ make test”輸出與googletest輸出樣式不同。 盡管測試結果看起來相同，但我對這些輸出並不滿意。

輸出差異

$ make test                 
Running tests...
Test project /path/to/sample/build
    Start 1: MyTest
1/1 Test #1: MyTest ...........................***Failed    0.02 sec

0% tests passed, 1 tests failed out of 1

Total Test time (real) =   0.02 sec

The following tests FAILED:
          1 - MyTest (Failed)

您可以使用環境變量來修改ctest的行為（make測試最終將執行該行為）。

例如：

CTEST_OUTPUT_ON_FAILURE=1 make test

這將為失敗的測試可執行文件輸出完整的輸出。
