package ogletest
// RegisterTestSuite tells ogletest about a test suite containing tests that it
// should run. Any exported method on the type pointed to by the supplied
// prototype value will be treated as test methods, with the exception of the
// following methods (which need not be present):
//
// * SetUpTestSuite() -- called exactly once, before the first test method is
// run. The receiver of this method will be a zero value of the test suite
// type, and is not shared with any other methods. Use this method to set
// up any necessary global state shared by all of the test methods.
//
// * TearDownTestSuite() -- called exactly once, after the last test method
// is run. The receiver of this method will be a zero value of the test
// suite type, and is not shared with any other methods. Use this method to
// clean up after any necessary global state shared by all of the test
// methods.
//
// * SetUp(testInfo) -- called before each test method is invoked, with the
// same receiver as that test method, and with a TestInfo arg. At the time
// this method is invoked, the receiver is a zero value for the test suite
// type. Use this method for common setup code that works on data not
// shared across tests.
//
// * TearDown() -- called after each test method is invoked, with the same
// receiver as that test method. Use this method for common cleanup code
// that works on data not shared across tests.
//
// Each test method is invoked on a different receiver, which is initially a
// zero value of the test suite type.
//
// Example:
//
// // Some value that is needed by the tests but is expensive to compute.
// var someExpensiveThing uint
//
// type FooTest struct {
// // Path to a temporary file used by the tests. Each test gets a
// // different temporary file.
// tempFile string
// }
// func init() { ogletest.RegisterTestSuite(&FooTest{}) }
//
// func (t *FooTest) SetUpTestSuite() {
// someExpensiveThing = ComputeSomeExpensiveThing()
// }
//
// func (t *FooTest) SetUp() {
// t.tempFile = CreateTempFile()
// }
//
// func (t *FooTest) TearDown() {
// DeleteTempFile(t.tempFile)
// }
//
// func (t *FooTest) FrobinicatorIsSuccessfullyTweaked() {
// res := DoSomethingWithExpensiveThing(someExpensiveThing, t.tempFile)
// ExpectThat(res, Equals(true))
// }
//
