They execute scheduled tasks regularly.

They define the state for a device configuration.

They collect SNMP logs from networking devices.

They utilize the target device agent to execute.

What is the purpose of running tests before writing code in test-driven development?

to provide proof of the work carried out

to find unexpected failures in the tests

Refer to the exhibit. Refer to the exhibit. A developer is part of a team that is working on an open-source project in which source code is hosted in a public GitHub repository. While the application was built, security concerns were addressed by encrypting the credentials on the server.
