使用 trompeloeil 单元测试框架和 TDD：https ://github.com/rollbear/trompeloeil/blob/master/docs/reference.md

给定以下测试用例

Testcase 1:
  Expectation_A: a() is called
  Expectation_B: b() is called

Testcase 2:
  Expectation_A: a() is called
  Expectation_C: c() is called

可以使用 TDD 轻松编写它们：

WHEN("")
{
    REQUIRE_CALL(*myMock, a());

    AND_WHEN("")
    {
        REQUIRE_CALL(*myMock, b());
        THEN("")
        {
            objectUnderTest.call();
        }
    }

    AND_WHEN("")
    {
        REQUIRE_CALL(*myMock, c());
        THEN("")
        {
            objectUnderTest.call();
        }
    }
}

但是，我不知道如何处理这种情况，当两个测试用例中的一系列期望相同时，在两个序列中一个期望/参数化区域不同之后：

Testcase 1:
  Expectation_A: a() is called
  Expectation_B: b() is called
  Expectation_D1: d1() is called
  Expectation_D2: d2() is called
  Expectation_D3: d3() is called

Testcase 2:
  Expectation_A: a() is called
  Expectation_C: c() is called   // differs
  Expectation_D1: d1() is called // same as TC1 from here on
  Expectation_D2: d2() is called
  Expectation_D3: d3() is called

我知道如何使用 TDD 编写它们的唯一方法是：

WHEN("")
{
    REQUIRE_CALL(*myMock, a());

    AND_WHEN("")
    {
        REQUIRE_CALL(*myMock, b());
        REQUIRE_CALL(*myMock, d1());
        REQUIRE_CALL(*myMock, d2());
        REQUIRE_CALL(*myMock, d3());
        THEN("")
        {
            objectUnderTest.call();
        }
    }

    AND_WHEN("")
    {
        REQUIRE_CALL(*myMock, c());
        REQUIRE_CALL(*myMock, d1());
        REQUIRE_CALL(*myMock, d2());
        REQUIRE_CALL(*myMock, d3());
        THEN("")
        {
            objectUnderTest.call();
        }
    }
}

有没有办法在测试用例不同后重新加入测试用例的执行流程，或者我真的必须复制和粘贴，只要 2 个测试用例不同？
