A demo about the unit test of gin-gonic/gin
Make sure you have a working Go environment (Go 1.2 or higher is required). See the install instructions.
To install gin_unit_test, simply run:
go get github.com/Valiben/gin_unit_test
To compile it from source:
cd $GOPATH/src/github.com/Valiben/gin_unit_test
go get -u -v
go build && go test -v
Here is a simple handler for login. Binding the parameters of the request to the User variable, and judge whether the password and username are right.
type User struct {
Username string `form:"username" json:"username" binding:"required"`
Password string `form:"password" json:"password" binding:"required"`
Age int `form:"age" json:"age" binding:"required"`
}func LoginHandler(c *gin.Context) {
req := &User{}
if err := c.Bind(req); err != nil {
log.Printf("err:%v", err)
c.JSON(http.StatusOK, gin.H{
"errno": "1",
"errmsg": "parameters not match",
})
return
}
// judge the password and username
if req.UserName != "Valiben" || req.Password != "123456" {
c.JSON(http.StatusOK, gin.H{
"errno": "2",
"errmsg": "password or username is wrong",
})
return
}
c.JSON(http.StatusOK, gin.H{
"errno": "0",
"errmsg": "login success",
})
}You can write a unit test for this handler like the following.
Firstly, you should set up the router to handle the requests.
router := gin.Default()
router.POST("/login", LoginHandler)Secondly, you should set the router of the utils so that you can use the utils to test the handler.
SetRouter(router)Then you can write the unit test function.
func TestLoginHandler(t *testing.T) {
resp := OrdinaryResponse{}
err := utils.TestHandlerUnMarshalResp("POST", "/login", "form", user, &resp)
if err != nil {
t.Errorf("TestLoginHandler: %v\n", err)
return
}
if resp.Errno != "0" {
t.Errorf("TestLoginHandler: response is not expected\n")
return
}
}Then you can run this test to check the handler.
You can find more tests and more specific information about how to use utils in the test/handlers_test.go.
