# dbassert

The `dbassert` package provides some helpful functions to help you write better

tests when writing Go database applications.  The package supports both sql.DB

and Gorm assertions. 

### Example sql.DB asserts usage:

```go

package your_brilliant_pkg

import (

    "testing"

    dbassert "github.com/hashicorp/dbassert"

)

func TestSomeDb(t *testing.T) {

	conn, err := sql.Open("postgres", "postgres://postgres:secret@localhost:%s?sslmode=disable")

	if err != nil {

		t.Fatal(err)

	}

	defer conn.Close()

	

	dbassert := dbassert.New(t, conn, "postgres")

    

	// assert that the db column is nullable

	dbassert.Nullable("some_table", "some_column")

	// assert that the db column is a particular domain type

	dbassert.Domain("test_table_dbasserts", "public_id", "dbasserts_public_id")

}

```

### Example Gorm asserts usage:

```go

package your_brilliant_pkg

import (

    "testing"

    dbassert "github.com/hashicorp/dbassert/gorm"

)

func TestSomeGormModel(t *testing.T) {

	conn, err := sql.Open("postgres", "postgres://postgres:secret@localhost:%s?sslmode=disable")

	if err != nil {

		t.Fatal(err)

	}

	defer conn.Close()

	db, err := gorm.Open("postgres", conn)

 	m := testModel{}

	if err = db.Create(&m).Error; err != nil {

    	t.Fatal(err)

	}

	dbassert := dbassert.New(t, conn, "postgres")

    

	// assert that the db field is null

	dbassert.IsNull(&someModel, "SomeField")

	// assert that the db field is not null

	dbassert.NotNull(&someModel, "SomeField")

	// assert that the db field nullable

	dbassert.Nullable(&someModel, "SomeField")

	// assert that the db field is a particular domain type

	dbassert.Domain(&someModel, "SomeField", "some_domain_type")

}

```
