+
+* Start server:
+sudo ./cloudflared tunnel --hostname HOSTNAME --ssh-server
+
+* Fetch token: 
+./cloudflared access login HOSTNAME
+
+* Create docker env file:
+echo "SSH_HOSTNAME=HOSTNAME\nSSH_USER=USERNAME\n" > ssh_server_tests/.env

-# Sql driver mock for Golang
-
-**sqlmock** is a mock library implementing [sql/driver](https://godoc.org/database/sql/driver). Which has one and only
-purpose - to simulate any **sql** driver behavior in tests, without needing a real database connection. It helps to
-maintain correct **TDD** workflow.
-
-- this library is now complete and stable. (you may not find new changes for this reason)
-- supports concurrency and multiple connections.
-- supports **go1.8** Context related feature mocking and Named sql parameters.
-- does not require any modifications to your source code.
-- the driver allows to mock any sql driver method behavior.
-- has strict by default expectation order matching.
-- has no third party dependencies.
-
-**NOTE:** in **v1.2.0** **sqlmock.Rows** has changed to struct from interface, if you were using any type references to that
-interface, you will need to switch it to a pointer struct type. Also, **sqlmock.Rows** were used to implement **driver.Rows**
-interface, which was not required or useful for mocking and was removed. Hope it will not cause issues.
-
-## Install
-
-    go get github.com/DATA-DOG/go-sqlmock
-
-## Documentation and Examples
-
-Visit [godoc](http://godoc.org/github.com/DATA-DOG/go-sqlmock) for general examples and public api reference.
-See **.travis.yml** for supported **go** versions.
-Different use case, is to functionally test with a real database - [go-txdb](https://github.com/DATA-DOG/go-txdb)
-all database related actions are isolated within a single transaction so the database can remain in the same state.
-
-See implementation examples:
-
-- [blog API server](https://github.com/DATA-DOG/go-sqlmock/tree/master/examples/blog)
-- [the same orders example](https://github.com/DATA-DOG/go-sqlmock/tree/master/examples/orders)

-## Customize SQL query matching
-
-There were plenty of requests from users regarding SQL query string validation or different matching option.
-We have now implemented the `QueryMatcher` interface, which can be passed through an option when calling
-`sqlmock.New` or `sqlmock.NewWithDSN`.
-
-This now allows to include some library, which would allow for example to parse and validate `mysql` SQL AST.
-And create a custom QueryMatcher in order to validate SQL in sophisticated ways.
-
-By default, **sqlmock** is preserving backward compatibility and default query matcher is `sqlmock.QueryMatcherRegexp`
-which uses expected SQL string as a regular expression to match incoming query string. There is an equality matcher:
-`QueryMatcherEqual` which will do a full case sensitive match.
-
-In order to customize the QueryMatcher, use the following:
-
-``` go
-	db, mock, err := sqlmock.New(sqlmock.QueryMatcherOption(sqlmock.QueryMatcherEqual))
-```
-
-The query matcher can be fully customized based on user needs. **sqlmock** will not
-provide a standard sql parsing matchers, since various drivers may not follow the same SQL standard.
-
-## Matching arguments like time.Time
-
-There may be arguments which are of `struct` type and cannot be compared easily by value like `time.Time`. In this case
-**sqlmock** provides an [Argument](https://godoc.org/github.com/DATA-DOG/go-sqlmock#Argument) interface which
-can be used in more sophisticated matching. Here is a simple example of time argument matching:
-
-``` go
-type AnyTime struct{}
-
-// Match satisfies sqlmock.Argument interface
-func (a AnyTime) Match(v driver.Value) bool {
-	_, ok := v.(time.Time)
-	return ok
-}
-
-func TestAnyTimeArgument(t *testing.T) {
-	t.Parallel()
-	db, mock, err := New()
-	if err != nil {
-		t.Errorf("an error '%s' was not expected when opening a stub database connection", err)
-	}
-	defer db.Close()
-
-	mock.ExpectExec("INSERT INTO users").
-		WithArgs("john", AnyTime{}).
-		WillReturnResult(NewResult(1, 1))
-
-	_, err = db.Exec("INSERT INTO users(name, created_at) VALUES (?, ?)", "john", time.Now())
-	if err != nil {
-		t.Errorf("error '%s' was not expected, while inserting a row", err)
-	}
-
-	if err := mock.ExpectationsWereMet(); err != nil {
-		t.Errorf("there were unfulfilled expectations: %s", err)
-	}
-}
-```
-
-It only asserts that argument is of `time.Time` type.

-## Change Log
-
-- **2019-02-13** - added `go.mod` removed the references and suggestions using `gopkg.in`.
-- **2018-12-11** - added expectation of Rows to be closed, while mocking expected query.
-- **2018-12-11** - introduced an option to provide **QueryMatcher** in order to customize SQL query matching.
-- **2017-09-01** - it is now possible to expect that prepared statement will be closed,
-  using **ExpectedPrepare.WillBeClosed**.
-- **2017-02-09** - implemented support for **go1.8** features. **Rows** interface was changed to struct
-  but contains all methods as before and should maintain backwards compatibility. **ExpectedQuery.WillReturnRows** may now
-  accept multiple row sets.
-- **2016-11-02** - `db.Prepare()` was not validating expected prepare SQL
-  query. It should still be validated even if Exec or Query is not
-  executed on that prepared statement.
-- **2016-02-23** - added **sqlmock.AnyArg()** function to provide any kind
-  of argument matcher.
-- **2016-02-23** - convert expected arguments to driver.Value as natural
-  driver does, the change may affect time.Time comparison and will be
-  stricter. See [issue](https://github.com/DATA-DOG/go-sqlmock/issues/31).
-- **2015-08-27** - **v1** api change, concurrency support, all known issues fixed.
-- **2014-08-16** instead of **panic** during reflect type mismatch when comparing query arguments - now return error
-- **2014-08-14** added **sqlmock.NewErrorResult** which gives an option to return driver.Result with errors for
-interface methods, see [issue](https://github.com/DATA-DOG/go-sqlmock/issues/5)
-- **2014-05-29** allow to match arguments in more sophisticated ways, by providing an **sqlmock.Argument** interface
-- **2014-04-21** introduce **sqlmock.New()** to open a mock database connection for tests. This method
-calls sql.DB.Ping to ensure that connection is open, see [issue](https://github.com/DATA-DOG/go-sqlmock/issues/4).
-This way on Close it will surely assert if all expectations are met, even if database was not triggered at all.
-The old way is still available, but it is advisable to call db.Ping manually before asserting with db.Close.
-- **2014-02-14** RowsFromCSVString is now a part of Rows interface named as FromCSVString.
-It has changed to allow more ways to construct rows and to easily extend this API in future.
-See [issue 1](https://github.com/DATA-DOG/go-sqlmock/issues/1)
-**RowsFromCSVString** is deprecated and will be removed in future
