+###Go-Mocket
+
+Go-Mocket is library inspired by [DATA-DOG/go-sqlmock](https://github.com/DATA-DOG/go-sqlmock)
+As inspiration library it is implementation of [sql/driver](https://godoc.org/database/sql/driver) interface but at the same time follows different approaches and has only similar API.
+This library helps to mock any DB connection also with [jinzhu/gorm](https://github.com/jinzhu/gorm) and it was main goal to create it
+
+List of features in the library:
+
+* Mock `INSERT`, `UPDATE`, `SELECT`, `DELETE`
+* Support of transactions
+* 2 API's to use - `chaining` and via specifying whole mock object
+* Matching by prepared statements arguments
+* You will not require to change anything inside you code to start using this library
+* Ability to trigger exceptions
+* Attach callbacks to mocked response to add additional check or modify response
+
+**NOTE** Please be aware that driver catches SQL without DB specifics. Generating of queries is done by *sql* package
+
+####Install
+```
+go get github.com/selvatico/go-mocket
+```
+
+#### Usage
+There are two possible ways to use `mocket`:
+
+* Chaining API
+* Specifying `FakeResponse` object with all fields manually. Could be useful for
+
+##### Enabling driver
+
+Somewhere in you code to setup a tests
+```
+import (
+    "database/sql"
+    mocket "github.com/selvatico/go-mocket"
+    "github.com/jinzhu/gorm"
+)
+
+func SetupTests() {
+    sql.Register("fake_test", mocket.FakeDriver{})
+    // GORM
+    db, err := gorm.Open("fake_test", "connection_string") // Could be any connection string
+    app.DB = db
+
+    // Regular sql package usage
+    db, err := sql.Open(driver, source)
+}
+```
+Now if use singleton instance of DB it will use everywhere mocked connection.
+
+##### Chain usage
+###### Example of mocking by pattern
+
+```go
+import mocket "github.com/selvatico/go-mocket"
+import "net/http/httptest"
+
+func TestHandler(t *testing.T) {
+    request := httptest.NewRequest("POST", "/application", postBody)
+    recorder := httptest.NewRecorder()
+
+    GlobalMock := mocket.Catcher
+    GlobalMock.Logging = true // log mocket behavior
+
+    commonReply := []map[string]interface{}{{"id": "2", "field": "value"}}
+    // Mock only by query pattern
+    GlobalMock.NewMock().WithQuery(`"campaigns".name IS NULL AND (("uuid" = test_uuid))`).WithReply(commonReply)
+    Post(recorder, request) // call handler
+
+    r := recorder.Result()
+    body, _ := ioutil.ReadAll(r.Body)
+
+    // some assertion about results
+    //...
+
+}
+
+```
