SNMP protocol is the internet standard often used a monitoring instrument. This happens because it’s a widespread tool within IP/TCP networks. And there are plenty different devices supporting it like switches, routers, surveillance camera and other devices, including IoT staffs.

Test Design is creating a set of inputs for given software that will provide a set of expected outputs. So, as it’s a creative process it’ll be good to have a set of rules or approaches that guarantee the quality of a final output (usually tests or test cases).

Probably you know if I run git log within a git repository, I could read a story of life. And I like this kind of stories because they show you everything about the code I may work with. From the other side, if I run git commit, I will add a new chapter to the story. And someone else will read it. That’s why I need to make sure the commit message, I wrote, will be a useful chapter.

In the previous post, we looked at the ways how to close connection safely. But there still is one more task: how to connect to a source on in the case when the interaction will happen? This task appears because a lot of connections are designed in a way that you have to connect to a source before start using the connection. Let’s see how lazy connection can be implemented.

Writing automated tests, we often have to interact with a database or a linux host. Different libraries allow us connecting to desired targets and interacting with them. Usually, a connection has to be created first, then it’s possible to implement any desired interactions, and the connection has to be destroyed in the end of the interactions. Looks like everything is very logical and simple. But why there are so many errors in the implementations?
