docs: //Some matcher libraries or legacy codebases require a *testing.T
  //GinkgoT implements an interface analogous to *testing.T and can be used if
  //the library in question accepts *testing.T through an interface
  //
  // For example, with testify:
  // assert.Equal(GinkgoT(), 123, 123, "they should be equal")
  //
  // Or with gomock:
  // gomock.NewController(GinkgoT())
  //
  // GinkgoT() takes an optional offset argument that can be used to get the
  // correct line number associated with the failure.
