How to perform integration testing in Go?
2020-09-29
Integration testing can be triggered by using Drone downstream plugin:
steps:
- name: trigger
image: plugins/downstream:linux-amd64
settings:
params:
- COMMIT_BRANCH=${DRONE_COMMIT_BRANCH}
repositories:
- repo/integration-test@${DRONE_COMMIT_BRANCH}
server: https://drone.example.com
token:
from_secret: drone_token
It can be separated with unit tests by using build tags:
// +build integration
package webserver_test
Then we can write code to perform integration test as usual.
Save draft mail in Zimbra web client using ChromeDP
2020-07-03
As an engineer, I want to automate everything as much as possible. This CLI tool is created to save a draft mail in Zimbra web client.
Read config file:
func initConfig() {
if cfgFile != "" {
// Use config file from the flag.
viper.SetConfigFile(cfgFile)
} else {
// Find home directory.
home, err := homedir.Dir()
if err != nil {
fmt.Println(err)
os.Exit(1)
}
// Search config in home directory with name ".zwc" (without extension).
viper.AddConfigPath(home)
viper.SetConfigName(".zwc")
}
viper.AutomaticEnv() // read in environment variables that match
// If a config file is found, read it in.
if err := viper.ReadInConfig(); err != nil {
log.Fatal(err)
}
fmt.Println("Using config file:", viper.ConfigFileUsed())
}
Google Calendar CLI
2020-04-13
Our company allows us to work from home some days a week. To do that, we have to create an event in Google Calendar.
I created this tool to run it from CLI.
First, take a look at this quickstart.
Create initical code by running:
$ cobra init
$ tree -L 2
.
├── LICENSE
├── cmd
│ └── root.go
├── main.go
Create event command:
$ cobra add event
$ cobra add insert -p 'eventCmd'
$ tree -L 2
.
├── LICENSE
├── cmd
│ ├── event.go
│ ├── event_insert.go
│ └── root.go
├── main.go
database/sql: never ignore errors
2019-10-16
I’m reading Building RESTful Web Services with Go. And in chapter 4, there is an example to play around with SQLite:
db, err := sql.Open("sqlite3", "./books.db")
if err != nil {
log.Fatal(err)
}
statement, err := db.Prepare("CREATE TABLE IF NOT EXISTS books (id INTERGER PRIMARY KEY, isbn INTEGER, author VARCHAR(64), name VARCHAR(64) NULL)")
if err != nil {
log.Fatal(err)
} else {
log.Println("Created table books successfully")
}
statement.Exec()
statement, err = db.Prepare("INSERT INTO books (name, author, isbn) VALUES (?, ?, ?)")
if err != nil {
log.Fatal(err)
}
statement.Exec("Life is a joke", "The Javna brothers", 123456789)
log.Println("Inserted first book into db")
rows, err := db.Query("SELECT id, name, author FROM books")
var tempBook Book
for rows.Next() {
rows.Scan(&tempBook.id, &tempBook.name, &tempBook.author)
log.Printf("ID: %d, Book: %s, Author: %s\n", tempBook.id, tempBook.name, tempBook.author)
}
How do I build this blog?
2019-10-11
Recently, I decided to find a new job as a Golang developer. So, I updated my resume, sent to my friends to ask for review. Then I submitted it enclosed herewith a cover letter to recruiters. Some didn’t reply, and the other replied with a message like this “You are so good, but I’m so sorry…”.
What is the reason?
As you can see in my resume, I started my career as a .NET developer, then my passionate on Linux and open source lead me to a different direction: system administrator. I dedicated myself to this role for a significant period before transitioning back to work as a Golang developer 2 years ago.
