// TestControl is an interface requiring a subset of *testing.T which is used
|
|
// by the test guards and helpers in this package. Most callers can simply
|
|
// pass their *testing.T value here, but the interface allows other
|
|
// implementations to potentially be provided instead, for example to allow
|
|
// meta-testing (testing of the test utilities themselves).
|
|
//
|
|
// This interface also describes the subset of normal test functionality the
|
|
// guards and helpers can perform: they can only create log lines, fail tests,
|
|
// and skip tests. All other test control is the responsibility of the main
|
|
// test code.
