// other calls to Convey(), Reset() or Should-style assertions. Convey calls can

|
// be nested as far as you see fit.
|
|
//
|
|
// IMPORTANT NOTE: The top-level Convey() within a Test method
|
|
// must conform to the following signature:
|
|
//
|
|
// Convey(description string, t *testing.T, action func())

//
|

// Don't worry, goconvey will panic if you get it wrong so you can fix it.

//
|
|
// Additionally, you may explicitly obtain access to the Convey context by doing:
|
|
//
|
|
// Convey(description string, action func(c C))
|
|
//
|
|
// You may need to do this if you want to pass the context through to a

// calls your handler in a goroutine (httptest comes to mind).

// how goconvey should treat failures for So()-assertions in the block and

// nested blocks. See the constants in this file for the available options.
|
|
//
|
|
